| Noticed lots of white smoke coming out tail pipe while driving. very unusual. car then stopped on freeway. had to get pushed by another car to side if freeway. towed car home to driveway. tried to crank egine and heard real loud pop coming from under hood. car did not turn on. tried to start 5 more times but each time it just sounded like a real short crank type sound like as if engine is having a hard time turning. after fifth time, engine started and this time the smoke coming out tail pipe was white/blueish and lots of it. engine stopped. also noticed that all the coolant was gone from coolant container and there is a high burning smell of coolant coming from engine. this might be a cracked upper intake or lower intake. these are made of real cheap hard plastic which could be the primary reason of engine failure. car is now parked in my backyard. | |||

| Routine service revealed that i have an antifreeze leak in the manifold area. *nm | |||
| 01/03/2003 | 1 | 03/04/1998 | |
| I have been told by two mechanics that i need to change my antifreeze from dex-cool to ethylen glycol, as the dexcoolant is dirty and sugary and i am looking at electrolisis problems in my cooling system if i don't change it. why would a reputable company like buick put an inferior product in their vehicle? is there a class action suit being filed against dex coolant?. *ak | |||
