Hey guys, last winter I had the check engine light come on in my 02 prix gt & when it was scanned I was told it was the low coolant temp code and was caused by a bad thermostat or coolant temp sensor. How do I know which one it is & are they hard to change? Thanks.

Works but Step#2 can be bypassed by just unscrewing the bolts off the housing, replace the thermostat, re bolt down housing and bleed the coolant systemOriginally Posted by bandits grand prix

First off...
There is no low cooalnt code. There is a not warming up quick enough code.
Second.. yes..program th epcm.
Three...Bandit.. where the hell have you found a $2 thermostat in Connectiscrewyouintaxescut?

well I don't have a programer so can any shop do that or do I need to take it a performance shop?

You need someone who can reprogram your pcm. Typically shops have super scanners, not programmers.
Oh..your Indiana? Look up PRJ Performance.

thanks for the heads up on PRJ but they're about 2 1/2 hours away from me so I'll see if I can find someone locally who can do it.

Honestly...it is really worth the drive...trust me.
Paul is a legit source.

There's
1. God
2. Tied PRJ/TEP
2.5 hours. Paul would not only change the fans but likely fully tune you for a great overall car.
