Question about 2000 Chevrolet Blazer

I recently replaced a thermostat in our 200 chevy blazer and it suddenly put on the service engine soon light. What may be the cause?

    So did mine after I replaced my thermostat last week, but I learned before that it comes on because I have California emissions (I live in AZ) and it's not working 100%. It's not hurting the truck, but wouldn't pass emissions in CA.

Check and make sure that there are no vacum lines disconnected if all else fails you can go to any autozone or advance auto parts store and they will scan your car for free! and tell you why it is on.

2001 Chevy Blazer. Service engine soon light on. Check comp and replaced Temp. sender. Light came back on and it says it's the thermostat temp. sensor. Any idea where this is located?


The temperature sensor is located on the intake manifold by the thermostat housing. Check the wire leads first and if that's good, replace the sensor and thermostat. The 4.3 was programed by the factory to run it's best at 190'", if it runs too cold. The mil light comes on indicating a temperature sensor failure.

I want to find out how to turn off check engine light for a 2002


You can disconnect the battery for 1-2 minutes and then re-connect it. The only thing is that if you haven't fixed the problem, the light is going to come back on. Have your vehicle scanned for the trouble code and post it on here. We can help you from there.

Thermostat stuck, and temp relay shut down to protect engine.
Everyhing seems to be working properly except the thermostat.
Yes, tolerances in the engine are tight, so thermal expansion could have caused further damage to your cylinders or pistons ETC.
If this happens again before you have a chance to replace the thermostat... squeeze the upper radiator hose repeatedly and the thermostat may free up.
Reccomendation is replace the thermostat.
