98 Camaro LOW running temp. I just recently purchased an all original, terrific running 98 Camaro Converible with only 86000 miles on it. Everything seems great and I've been driving it for weeks with no...

I would suspect either the temp guage or the coolant temperature sensor being inaccurate. The new thermostat is probably working good, or else you wouldn't have a very warm heater. If you have electric radiator fans, you might check to see if they are running all th time. Electric cooling fans should only come on when the temperature sensor reaches a predetermined coolant temp, or when the a/c or defroster is turned on. If the fan runs all the time, the engine would not reach normal operating temperature.

I bought a thermostat from advance auto parts for my 1999 cadillac deville but I was told that it should only be bought from a cadillac dealership but I used it anyway. I put the thermostat on and the car...

Who did all this work?
Was the water pump bad?
Was the radiator, so clogged it could not be cleaned?

What diagnostics was done?

Is the car actually over heating? That is where you start

All that work may have been for not

When you removed the stat,the temp never went up,only the gauge,
can not run a veh without the stat, the temp sensor needs it in there

Is the exhaust converter partially blocked?
Is the engine running rich

Have the data looked at.

Engine revs high after driving a while in the morning

Sounds like the theromstatic is sticking, making the temp to run higher than normal. The temp should be around 185 to 190 tops. Also check the flues on the radiator, make sure it is recirculation well once the theroms. open up. I not sur if this has a clutch fan or and But make sure it is pulling air thru the radiator well, to help to keep the motor cool.

Over heating problem...

Could be a few things but either way, don't wait to have the cooling system checked out, do it now & possibly save $1000's later.
Check your coolant level first, make sure all belts are there. Rad fan should be coming on when it reaches operating temperature etc. Just bought it from who, a dealer? If it was a dealer head back to him a.s.a.p. and give him a chance to make it right, and pay close attention to what he says it is/was.
