ELECTRICAL SYSTEM | |||
12/01/2008 | 1 | ||
Its well known that the power steering/alternator setup on the 1990-1994 lexus ls400s are poorly designed. the power steering pumps are known to spring leaks. they are located directly over the alternator charging system and the leaking fluid shorts out the alternator, leading to failure. i have had two of these and both were leaking and after researching, its hard to find a 1990-94 ls400 on the road that does not have a leaking power steering pump. the pump seals should have been better manufactured, placed in a different configuration, or a alternator guard placed over the alternator to keep the fluid from seeping into the alternator causing the premature failure. i have seen a couple of these with fires in this area and can understand it being a possibility with the power steering oil leaking down into the alternator. so, not only do the pumps leak externally (they also leak internally and suck into the engine), but they also ruin the alternator and cause a potential fire hazard. another problem area with this same car is the hvac controls will turn black after a few years, creating a safety hazard, because you cannot see what your heating/defroster settings are at night. *tr | |||
