20 Most Recent 1990 Oldsmobile Cutlass Calais Questions & Answers

Under the car on the drivers side behind the drivers door. Replace it, it is probably way over due. But my guess(if you have spark to the plugs) is the fuel pressure regulator. No spark to the plugs would be the crank sensor. Under the crank pulley.

Most cars don't have a drain plug for radiators anymore! Just unclip the bottom hose from the radiator to drain it!

I have always had a place in my heart for the Olds Cutlass. I own a '90 Olds Cutlass Calais--WITH the fuse box COVER. I went out to the car and removed the cover and have it next to me so that I can type the EXACT fuse order as they appear on the inside cover.There are 2 col. When I've finished the l/h side, I'll make a line to indicate the start of the r/h side. I will also put the Circuit on the left & fuse on the right. If you are ready, HERE WE GO:

Hi Ronald,That vehicle is equipped with one of the easiest heater cores in the world to replace. Here are the instructions form the service manual:Drain cooling system. Raise vehicle. From underneath, remove heater hoses from heater core. Remove drain tube. Lower vehicle. Remove right and left side sound insulator panels. Lower heating duct and hoses. Remove heater core cover and heater core. To install, reverse procedure. Fill and bleed cooling system.HINT: I never drain the cooling system to replace a heater core. It is not necessary if you use a couple pairs of long-nose Vise-Grips to clamp off the heater hoses before you disconnect them from the heater core. That way, the only coolant you will lose is what is actually in the heater core itself.

if it stahls when it hot and while ur slowing or putting it in gear i suspect the transmission torque control solenoid whicjh unplug the harness from the transmission ull be fine other wise u might have faulty fuel injectors
