Running hotter after temp sending unit install

[ConcepTrs913]

After I installed the little gold temperature sending unit my car has been running hotter than normal, but it doesn't move from that position and doesn't overheat.

It looks like this...

Any ideas? Is anything even wrong?

Are the cooling fans running at this point ? They should be going high speed at that high of a gage reading. Engine is running too hot, imo, make sure the coolaing system is filled properly, you don't have an air pocket.

well i know my car is filled up w/ coolant, but how do i figure out if there are any air pockets. by cooling fans you just mean the ones up by the radiator?

 

[eepals]

By now the air pocket, if there was one, is gone since, the engine has cooled off. The electric fans (mounted on radiator) have a low and high speed, low speed, IIRC, turn on around 206 degrees, high at 226-230. Both fans run at the low or high speed together.
Is it still running hot?

Which sending unit did you replace? The one that sends a signal to the PCM or the one that sends a signal to the instrument cluster? Maybe it is defective? :shrug:

ill have to check my car later because i dont have it right now im at school. i had to drive it a long time the other day while it was running hot and there were no problems at all that is why i am confused to see the temp so high.

If it doesn't move, your sensor is probably faulty

get a scanner that can read the engine coolant temp and check where it is. could be that the needle is just off.

but if it doesn't move then the sensor itself could be faulty.

 

[ConcepTrs913]

the sensor moves as the engine heats up, but once it is there it doesnt move which makes me think that the needle might be off

 

[BrApple]

no once at temp the duratec temp guage doesn't normally move. but most don't read as high as your picture. again get a scanner and see what the temp really is.

Did you use teflon tape? I read somewhere not to use it, because it could keep the sensor from getting a good ground, and cause the needle to read higher.

No, just took out the old one and replaced it w/ the new one.

 

[tigerbalm]

where did you get it from? I bought one from advanced auto recently that reads higher than the old one, but not by that much.

 

[ConcepTrs913]

i got it from pep boys...

 

[ConcepTrs913]

so the last question i have is it possible that the new temp sensor reads higher than the stock one for some reason? or do i have to calibrate the gauge somehow?

 

[Lord Stanley]

If it is a bad sensor it will... Why did you replace it in the first place? And you never mentioned which of the two cooland sensors you replaced...

 

[ConcepTrs913]

i replaced it because mine went bad. i replaced the gold sensor that is about 5 inches lower (and a little left) of the accordion tube to the intake...
