1990 Plymouth Acclaim Problems

Engine Oil Leaks

On 4cylinder engines, engine oil leaks are common from the valve cover gasket, cam plug, and cylinder head gasket.

HVAC air flow switching to defrost under heavy engine load

The heating, ventilation and AC (HVAC) system may  change to defrost mode under heavy engine load conditions when low engine vacuum is produced. This can often be corrected by installing an additional vacuum check valve with reservoir to help stabilize the vacuum supply to the HVAC system.

Hesitation caused by plugged EGR back pressure tube

A hesitation on acceleration may be caused by carbon build up on the EGR valve back pressure tube. Cleaning the tube will generally restore proper EGR system operation, eliminating the associated hesitation.

1990 Plymouth Acclaim Reviews

I bought my plymouth acclaim second hand from a friend of my dads, for an older car, it runs pretty great. My only complaint is it's electrics. I find myself replacing fuses every couple of months, while they arent expensive or hard to replace, it is annoying when your wipers stop working, or when your radio stops, break lights, headlights, etc. For an old car, its a great one. It's not much to...
Awesome car that just keeps on running - forever. Best gas mileage in any car I've ever owned. It passes gas stations ALWAYS! The heater blows heat in 5 minutes and you'll think you're in Egypt with pyramids and sand dunes. Engine is reliable, little to no maintenance with regular oil changes since 1990. Its 09 and still have original brake parts - can't wear this thing out.
