Top 10 1998 Oldsmobile Aurora Questions & Answers

how do you know if your lighting module is bad in a 1998 Oldsmobile Aurora?

Here is the common cause of surges, stalls at stops, slow idle speed, erratic idle speed, rough idle and engine hesitation (and other problems), it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.

NO-NO-NO-NO NO

If you have to use stop leak drain out some coolant and remove the upper rad hose and poor it down there. IF you put it in the reservoir it will sit there and stop the return. You will think it is full and your system will be empty.

If you have 4.0 you may have a head gasket leaking. If it is running ok and you are loosing coolant contact me back and I will tell you a good fix that works

NO heat because there is no coolant flowing throught the heaster core. Car is overheat since there is no coolant circulating in engine water jacket.
Check the coolant, if it is low, then check the oil level. If oil level is high then the head gasket is blown so coolant gets into the engine therefore there is not enough coolant to cool the engine.
If the oil level is OK and coolant level is OK then Need to check 3 following things:
-Bad thermostat is not open causing coolant stagnant then engine overhet.
-Bad water pump is not pumping coolant so there is no coolant circulating to disipate the heat.
-Bad radiator blocks the coolant flow from top to bottom radiator.
Good luck.
