95 Deville coolant temp sensor


Recommended Posts

I have a 95 deville concours. It was overheating. I took it to the shop they replaced the radiator,water pump,thermastat and new temp sensor. it still ran hot. They pulled the computer to see if there wasw a problem with it because they said the engine temp did not get over 220. They unplugged the coolant sensor and the car ran fine. Im at a loss for words. What can I do to fix this? I know i cant roll with it unpluggeed? Does anyone have a clue of what i could do?

You need to explain this, its unclear.

They PULLED the computer?, what do you mean by that statement?, they replaced it with a KNOWN GOOD computer?

What do you mean by "because they said the engine temp did not get over 220"?

You have not been clear, it is hard to understand what you are saying as you relate those two states to eachother, lots is missing

Are you saying they replaced the computer THEN the temp did not get over 220?

Please explain clearly

Yeah...what Body by Fisher said...

Was it "REALLY" over heating and boiling coolant out...or was it just "INDICATING" that it was overheating??

You mention "TEMP SENSOR" and "COOLANT SENSOR"...

Is that "TWO DIFFERENT THINGS"...or are you using different words for the "SAME THING"??

Please clarify a little so that we can better help you...

In reply. They pulled the computer that is in the car and tested it to see if it was bad. It tested ok. They replaced the coolant temp sensor and the on dash display kept saying check coolant engine hot turn off engine even thought the temp did not get over 220.

If you do in fact have a bad coolant temp sensor, the PCM should have detected that. Check for codes
