 Tl*the contact owns a 1998 chevrolet venture. while idling in traffic or on an incline, the heat temperature gauge fluctuates. the vehicle is also losing antifreeze. the contact has been adding one half gallon of antifreeze per month and does not know why. when the weather becomes warmer, the check engine light illuminates sporadically. the light does not illuminate in the winter. the purchase date and powertrain were unknown. the current mileage was 160,000 and failure mileage was 130,000.

 I noticed that the vehicles coolant level had been dropping over a period of severla weeks. after having it tested it was discovered that the lower intake manilfold had a slow leak and needed replaced. the vehicle had less than 70,000 miles on it and it seems very unusual for this to happen so soon.

 The 1997-2000 venutures have problems with the engines, the intake gasket breaks down causing anti freeze to mix with the engines oil causing the cam shaft to crack, in our case there was no leaks under the van and there was no warning either the van was running well that morning and when my wife was driving down the street there was 2 short bukles from the van and everything shut down including steering which was difficult to do, is it going to take someones family to die on the side of the road before gm will do anything about this if my wife had been on the highway then there would be no way that she would have made it without being hit, even then she had 3 young children in the van ages 3-8 and was almost hit from behind, because it was an industrial highway speed limit of 50mph and not much room on the shoulder to park. there are many complaints about these vans and yet no one seems to be doing anything. this website has complaint after complaint, www. complaints.com and www.gm-v6lemons.com has hundreds of complaints along with other websites of people experancing the same problem. how many people have to die before anything is done? gm doesn't seem to care even though their dealerships have stated their is a problem with the engines. engine shut off and failure are serious problems . *ak

 I have a 1998 chevrolet venture with 82,651 miles. the vehicle would slowly dissipate coolant, which i replenished as needed. then a major coolant leak occurred at the engine block. barnard chevrolet of churchville, ny 14428 repaired the lower and upper intake manifold gaskets, and the rear head gasket. each had detiorated from the dex cool, causing the leakage. the dealership refused any customer assistance, despite my providing them with technical service bulletin #03-06-01-010. although the dealer provided a complete and professional repair, i believe that evidence is quite clear that the dex cool coolant and the gasket materials used by gm results in a defective product, and that gm must pay for these repairs. i also believe that that nhtsa has a responsibility to the american consumer to hold gm accountable. the bush administration seems to have completely suppressed this issue in terms of government followup. what a shame, the lobbyists win again. middle class americans left with the bill. *ak

 Heater not working due to a faulty manifold gasket that allowed the coolant to leak out of the engine of our 1998 chevrolet venture. i was told by the service tech that gm is now producing a better gasket to fix the problem. that's great!! i would like gm to pay the $798.67 bill for having to replace the first gasket that was not properly tested by engineering. this problem is very common, and should be a recall item. *jb

 I had the coolant flushed one month ago at the local dealer. driving on the freeway near home, the low coolant light came on. no indication on temperature gauge that coolant temp ever exceeded even halfway through the normal range. the next morning, the van runs rough and has a light coolant smell from the exhaust. took it to dealer for diagnosis. dealer said that the intake manifold gaskets failed allowing the van to overheat and blow the head gaskets. repair estimate is $2500 and with only 88k miles on the van. this is the second time that the intake manifold gaskets have failed. first time the intake gaskets failed was at 45k miles right after i bought it. there was no overheat or head gasket failure on the first incidence. *jb

 Leaking coolant led to engine failure. gm and dealership try to shift blame to me. they say there is no problem. the vehicle just stopped in the middle of the road. i had to push it to the side of a busy street with a small child inside. the engine oil filled with anti freeze and ceased up without warning. it had been to the dealership to have the low coolant light checked and they just added stop leak and said it would be fine. the lower intake manifold gasket was leaking. this has been well documented for over a year but gm is still in denial. my 1998 chevy venture was purchased used in september 2001. the vehicle only had 40,000 miles on it. i brought it to the dealership in sept. 2002 for 15 point inspection and oil change at about 45,000 miles. this was last day under warranty. in january 2003 the low coolant light came on. i checked the coolant level at it looked almost dry. there was no prior evidence like stains on my driveway. they said good thing i brought it in right away and flushed and filled it and said there was a small leak in one of the gaskets and added stop leak. in may the engine seized up and i needed to replace the engine with a rebuilt one at a cost of $4000.00. the vehicle has less than 50000 miles on it. the dealership and gm assistance claim no knowledge of this. in july my neighbor who owns a 2000 chevy silhouette has the same thing happen and needs his engine replaced. a friend of mine says he had his gasket fixed while under warranty. please help me and the thousands of others who have been hurt because gm refuses to accept responsibility for what is obviously a manufacturing defect. i feel the only option that i have is to go to small claims court where i probably won't have a chance against general motor?s lawyers. i have a couple of web sites that have been sort of like my support group since my engine failed. i don't know if you are aware of any of them.

 Car began losing coolant at about 20000 miles. had to keep topping coolant tank. presented to local dealer at 35,500 miles to be repaired. coolant sensor replaced, problem persisted. wife's car (1999 venture) began having same symptom, researched and found that this is a widespread problem with intake manifold gaskets (recently redesigned by gm). this problem can allow coolant to mix with oil, and oil with coolant. can result in sudden catastrophic engine failure (camshaft breaks due to insufficient lubrication). stranded vehicles will present multiple safety hazards.

 Leaking intake manifold gasket leak. leaking coolant. repair estimated to be $800 by elco chevrolet in ballwin, missouri. we discovered through research on the internet and talking to mechanics at a local auto repair franchise that this has been a problem with the chevy venture vans. we are looking for relief from gm-this is not the first problem we have had with coolant leaks in the van and are now wondering if this problem was undetected and we have been repairing other items needlessly (water pump, etc.) when this was the true source of the problem. we are very concerned about the future of the engine on this vehicle with this problem.

 1998 chevy venture, engine light came on, pulled over engine tapping & smoking. no oil light or change in temp, gauge observed. had to walk on interstate 1.2 miles took ride from unknown couple, had van towed. diagnoses was: intake gasket collapsed, causing connecting rod to go through engine. dealership & gm customer care refused any assistance. overwelmed by severity of this gasket problem readily available on the internet. we replaced our engine with a used one, that is all we could afford. it definitely was the faulty gasket that caused our engine to be replaced. when this first happened, no dummy light came on, nothing to even tell me there was a problem, such as low oil or service engine. the mechanic who replaced our engine told us he has seen several chevy venture vans with the same exact problem we had. we had the servive done at d&n garage 4929 south m-76 west branch, mi 48661, the owner is nelson smith. the phone # is 1 800 203 8504. it cost us almost $1600. to replace the engine, we lucked out finding one that had only 40,000 miles on it. nelson made sure to put the new gasket on this engine. the gm dealership here refused to help. where we bought the van refused to help, the gm helpline just very rudely told me it was my problem.

 Kept loosing coolant - initial pressure test did not detect leak. asked them to check intake manifold & gaskets. they detected leak. cost to repair - 673.00. do not know yet if any damage was done to engine.

 At 60,000 miles my chevrolet venture started to leak coolant and i took it to my local chevrolet dealer and they said that the intake manifiold gasket needed replacement. cost approx. $800.00 including cooling system flush and tax. dealer said that gm was not paying for all or part of the repair and in fact they have not commented to it's dealers about the failure of the intake manifold gaskets at all. obviously gm does not want to admit a problem with the 3.4l engine. my research finds that this is a very common and costly problem with these vehicles.
11/15/200283350
 Current problem is leaking coolant with ticking sound in engine at startup until engine is warm. diagnosed by dealer as blown head and intake gaskets. estimated cost is $1300 for gasket replacement and another $660 if head is cracked. mileage is 83350. many other reports exist of this problem in chevrolet ventures with some leading to engine failure. 3.4l v6.

 Engine coolant is leaking into engine. suspect bad intake manifold gasket, after exhaustive research on web.
01/15/20030
 Since purchasing this van i have had numerous problems, with the most recent being an engine replacement. this problem stems from the bad design of gm's intake gasket which breaks down and causes anti-freeze to leak into the engine causing premature wear and/or replacement.

 My 1998 chev venture was getting coolant into the motor oil which caused it to start ticking.i took it to the dealer and they said it was the intake gasket. they fixed the problem which cost me $1500.00. three months later the engine blew up .i had to get a reman.engine which cost $4000.00.i feel because of the faulty gasket this lead to my engine problem.

 I bought my 1998 venture in nov. of 2001. it had 66000 on it. it seemed to have the smell of antifreeze. in december of 2002 someone told us that the gaskets were noted for leaking. my husband replaced it, and gave it an oil change in feb. it was thick and dark orange in color. it started knocking when you accelerated. so once again my husband has it torn apart and found the crank shaft is coming apart due to the antifreeze leaking into the engine. now i am paying on a dead horse. we can't afford to get it repaired. it would be nice if gm would recall this. *jb

 Intake manifold gasket leak and engine seal leak on a vehicle that has been serviced exactly as recommended in the owner's manual. simple internet research (including this webiste) has shown a pattern of failure for these parts on this vehicle. gm customer service acknowldged problem but would not pay any of the $1,200 repair bill since the vehicle has 80,000 miles on it. this is a huge out-of-pocket expense for a part with a history of problems. i personally know two other 1998 venture owners who have had the same repair.

 I own a 1998 chevy venture with the 3.4l engine. i am constantly loosing antifreeze and oil disappears with explanation. i am still under a warranty but the dealership says it cant find anything wrong with it. i am concerned that my engine might seize or fail while driving down the interstate due to a design flaw in the intake manifold gasket. the coolany that chevy uses dexcool has been known to eat away the gaskets, so large a scale has this happened that gm has switched coolants to prestone extended life. i want a recall done free of charge to fix this problem. it is definitly a safety issue as most have complained about cams breaking and loss of power. someone is going to die because of this.

 For the 2nd time since the date noted below, i am experiencing intake manifold failure on my 1998 chevy venture. in 2003 it was replaced while the vehicle was still under warranty at 34,000 miles. now, just shy of 2 years later, and at 53,000 (at my own expense and a cost of $1200.00)) it needs to be replaced again. the reason i am contacting you at this time is that gm does not recognize this as a recallable issue with their vehicles. i spoke with glen kuniyuki on 12/7/05, and sylvia jabouin on 12/8/05, at gm customer service. they said that since this was not a recallable issue and until such time that the nhtsa made them recall the vehicles involved, that they simply were not going to recognize that this is a common problem to gm models, and recommended trading it in for a newer model. while researching this problem, i found several websites where many other gm customers are experiencing the same repetitive problem with no satisfaction from the manufacturer. i am providing you with only four, but there are many out there.

 Dt: consumer owns a 1998 chevrolet venture. at 55000 miles the intake manifold gasket went out. the vehicle was maintained immaculately. this happened in october 2003. vehicle was fixed by a dealer on october 10, 2003. he then checked the internet to find that this was a common problem due to a coolant that the manufacturer used. on july 2, 2005 the head gasket failed suddenly, vehicle had 75,000 miles. this was two weeks after a garage had done a 75000 mile check up on vehicle. well over $40000 was spent. he did further research on the internet to find many other complaints on this issue. he felt this wa a safety issue, and it was endangering the life of his family. he contacted manufacturer, and was told that they would call him back, after not being called back by the manufacturer and him calling manufacture often back they finally made him an offer of a discount on something. he refused the offer,. he felt that the offer was not near what he had spent on repairs that manufacture should have paid for repairs. *ak

 I am going to need to repair my minivan due to the problem with the coolant leak and i really can not afford this and may have to have the van sit until i can. i cannot believe after all the complaints i have read on here that there is not a recall on this or the headlights. i will not purchase another chevy vehicle again because this is a costly repair that is not the consumers responsibility, its obvious that this needs a recall. i do hope you come to your senses about this costly repair to the consumers because i will let every one i possible know that chevy knows about this costly problem but refuses to accept responsibility as i am sure others that have this problem have told numerous people and you sales will drop so low that you will wish you would have had a recall. *jb

 My family and i were on vacation driving from butler, pa to cape canaveral, florida. i was driving on i-95 near savannah, ga on june 26th when i noticed my temperture gauge was moving up and down. car never boiled over or loss any anti-freeze. i stopped at a pep boys repair shop at which time they advised me that my thermostat needed replacement. it appeared the dex-cool antifreeze that gm requires to be used turns into a sludge at high temperatures. entire cooling system was sludged up by the dex-cool. after installing new thermostat and anit-freeze engine was idling rough. car was taken to chevrolet dealer nearby - chevrolet dealer said engine needed replacement. - anti-freeze was entering cylinders #1 and #2. chevrolet dealer charged over $6,000. i feel chevrolet dealer overcharged as i was traveling from out of state - my local chevrolet dealer quoted $3,700 for same work. my local mechanic advised me it's common knowledge that dex-cool is a defective product that has ruined many engines, radiators, heater cores and thermostats - gm refuses to acknowledge the problem while the damage continues. my vehicle was purchased new by me - garage kept - well maintained - 112,000 miles at time of failure. *ak

 I backed the van out of my driveway at home and placed the car into drive. as i started to move forward, the gas pedal felt harder than normal but i attributed that to being left outside all winter. i pushed the gas pedal harder to get to car to move forward. and immediately i felt the pedal unstick . at that same moment, the engine raced to full throttle and raced forward with the van continually going faster and faster racing instantly to 50 miles an hour and still accelerating. at the beginning of the sudden acceleration, i tried to apply the brakes but could not stop the van or stop the acceleration. i turned off the ignition and finally braked the van to a stop. this all happened on the side street of my subdivision before i could get onto the main road. luckily there were no cars or people in my way and i was able to get control of the van without hurting myself or others, the van was brought back to my driveway where it remains. i have not contacted the dealership at this point as i do not want to pay to have this 12 year old van repaired at my cost nor do i ever want to drive this van again. *tr

 I purchased a 1998 chevrolet venture new for approximately $27,000. after 4 1/2 years i had to replace the lower intake manifold gasket at a cost of about $500. i maintained the vehicle to the manufacturers specifications even changing the oil every 3 to 4000. on labor day 2003, a little more than 5 years after i purchased the vehicle, i broke down returning from a family vacation with the car packed and my three kids. the car had to be towed to the nearest chevrolet dealer. 75 miles from home. bottom line the cam bearings spun in the engine and the dealer said the car was worth $300 as is. it needed a new engine at a total cost of $6150. gm customer service agreed that this was premature engine failure but that the engine had 72,000 miles and according to gm the life expectancy of that engine is only 100,000 miles. they said i got almost 75% of the engines expected life and they offered me 25% of the cost incurred by me to install a new engine. gm needs to recognize that the faulty gasket on the lower intake manifold caused this problem by allowing antifreeze to enter the engine. gm should have reimbursed me the cost for the gasket replacement and the engine. normal wear and tear i expect, but to have a vehicle worth about $7,000 one day and $300 the next is not fair. i will never buy another gm product as long as i live and i will let as many people i know how gm stands by their product. *la

 I recently purchased a used 1998 chevrolet venture. upon checking the fluid levels yesterday, i noted that the coolant level was low, and the coolant appeared to be contaminated (probably by oil). this, coupled with abnormal temperature fluctuations and an odd tinge on my oil dipstick caused me enough concern to do a little research. i've found thousands of testimonials from gm owners, especially of the 3.1 and 3.4 liter v-6, who have suffered from a leaking intake manifold gasket. the damage ranges from a six hundred dollar repair bill to ejected rods/cracked heads/complete engine failure. this is obviously a widespread defect, and engine failure in any type of traffic is obviously a safety concern, especially in a family vehicle such as a minivan. i am currently looking for information regarding accidents caused by this defect. my complaint is the commonality lack of support for this problem, given the fact that gm is clearly aware that it exists (both by technical bulletin and the fact that all four of the local gm service departments i called recently referred to the problem immediately). it is unbelievable that a recall has not occurred on this poorly engineered, inherently dangerous dex-cool coolant system, when it corrodes engine operating parts and support structures, often undetectable in the lower engine area until catastrophic material failure. *la

 We had a manifold gasket on our 1998 chevy venture go bad earlier this year. it leaked anti-freeze into the oil. it appears that the anti-freeze leaking into the engine oil has caused failures in the strength of the crankshaft. and since this site does not combine similar problems, it may appear that there are just a few problems with the cooling system, gaskets and crankshaft on the 1998-2000 venture vans. you need to look at all the cooling system problem reports. now the crank shaft has broken. we have learned that of others have had the same problem with this van. the local dealership has told us it will cost over $5,000.00 to repair/replace the engine. i have had many different types of cars in the past, one nissan maxima we have now has almost 200,000 miles, with no engine repairs like this. i believe gm has had a major defect with the manifold gasket and cooling system on this van and has avoided a recall for this defect. we were just told to have a nice day by rose uhl and christy hardcastle of gm customer service. i think a $5,000.00 repair bill is something to make complaints about on a van that cost $23,000.00. *jb

 After much research with area gm dealerships and your website, it appers that the 1998 venture mini-van's intake manifold gasket develops a leak at 80000 to 90000 miles. i had this replacement in may 2002. since my van was out of warrenty by 1000 miles (it was shy 2 weeks of being 4 years old). i spoke with gm's customer service and they stated there was nothing they could do about it. even though i have maintained my vehicle on schedule for all tune-up/oil changes/tire rotations, etc. i ended up paying $575.00 to have the intake manifold gasket replaced. since then my van has never been the same. it is now in the shop in need of a whole new engine with only 82000 miles. it seems a piston rod spun and damaged the crank shaft. after much investigation, i was told that the problem with the intake manifold gasket could have caused all of this. now i am faced with replacing the whole engine with an used engine with 4,000 miles for $2400 + tax, getting a remanufactured engine for $3865 or trading in the car. i do believe an investigation in the leaking of the intake manifold gasket should definately be pursued. i would really appreciate any assistance. for the headlight, my headlight lens fall off while i was driven on a highway going about 55 mph. i never could found the lens and lucky the lens flying off did not cause a crash. i contacted the gm assistance program and once again was told there was nothing could be done to assist us. this wasn't a known problem. after investigating again, i see this is a known problem. replacing the lens meant replacing the whole headlight unit at the tune of $328.03. what is the consumer to do??no safety defect listed. *ak
