The low oil pressure light can be a faulty oil pressure sensor.But mostly its the pump itself. open the oil pan and check if the net is chocked if not then replace the oil pump and do install the new o ring supplied with the pump. And try changing the oil on time and a good brand is important. (if the problem still exists then u need to replace the crank barring and the cam bushings..Just kidding).

What does the red oil light mean on 1998 deville. also car has oil in it. stop engine now light came on too. Why ?


If your oil light is on, it means that the control module thinks there is no oil pressure. It could be a bad oil pressure sending unit, or it could be that the oil pump is out and that the engine is actually not getting oil. The engine would need to have a mechanical gauge put on to find out if it does have pressure.

Message on 96 Caddilac Deville Transmission Control Module


Please read the owners manual on this first then read on here.
Whenever this warning light or any other stays on in the dash it is indicating that the systems control module (or the system sensor in the case of lights like low oil pressure, door open indicators etc.) has detected a fault, it then disables the system (this applies to ABS,TCS, TCM, SRS and BCM faults and others) as long as the light is on. You must now have the dealer hook up a special electronic diagnostic tool and "scan" the system for the fault code that is stored for the problem(s)

1998 Caddilac DeVille overheated water in the oil blown head gasket. would it beworth fixing.


It depends if you really like the car or not how much it costs.and how many original miles your engine has on it now. It might be less expensive to find and put a good low mileage used motor in there instead vs. replacing the Head Gasket and rebuiling the Head.

I have a 1998 gmc sierra and mt oil pressure gets low after engine warms up ive been told its my rod and main bearing but i think it could be the oil pump but im not for sure please help


Well, they may be right in saying that normal engine wear is causing this problem as the distance between the bearings and the oil passages gets bigger, the oil pressure drops.

If you want to spend the money on a new oil pump, you can, but there is no guarantee that will solve the problem.

You're right, the oil pump's passages might be wearing along with the rest of the engine causing this gradual low oil pressur problem.

Have you had the oil changed along with the filter to see if maybe there's a circulation problem in the engine?

I had low oil pressure on my 1997 Cadillac Deville Limousine, that was intermittently flashing the low oil pressure light.

I read that it's recommended to change the oil to the proper viscosity and that seemed to clear up my problem on my GM Northstar engine.

It's worth a try.

Good luck on this repair.

1998 DeVille: what happens if I put 10w-40 oil in a 1998 cadilla...


I believe that 10w30 is recommended for the vehicle, but 10w-40 is a good substitute if 10w30 is not available.

Probably nothing bad will happen, but if the Driver Information System shows low oil pressure, revert back to the recommended viscosity.

STOP ENGINE-LOW OIL PRESSURE LIGHT COMES ON AFTER INSTALLING NEW


The idle may be to low or the motor is just old and a new set of rod bearings is need with an oilpump to bring the pressure back up.
