Have you checked the fan clutch?It comes equipped with a thermostatic clutch that engages at a certain temp.A faulty fan clutch either doesn't engage at all,or stays engaged all the time.If the clutch stays engaged all the time,it may cause the engine to run cooler than normal.Also what temp thermostat did you replace?Recommended temp should be a 185/190 degree range.

2007 Chevy Silverado 2500 HD. I was driving and my digital dashboard reported engine hot and AC turned off. My temperature gauge read cool. What do I need to replace?


This sounds like a bad coolant temp sensor that give computer false reading, check the coolant temp sensor connector and if it is good with no bad wires to connector then replace coolant temp sensor , when the computer gets a signal from temp sensor that engine is hot it turns fans on high speed to cool radiator and displays a/c turned off , if this truck does not have electric cooling fans then they wont run just explaining what happens depending on engine and cooling set up. replace coolant temp sensor and check connector.

I went for an emissions test today and it failed the mechanic said the car might be running too hot or too lean also notice the the heat gauge stays at cold when driving.HELP


I suspect you need a new thermostat. It should be running at 195 degrees F.

If the engine does not fully warm up, the engine can not go into emission control mode.

The engine temperature sensor sends a signal to the engine/emissions computer that the engine is now at normal operating temp. The computer then starts controlling fuel flow, EGR, etc. so that emissions are being controlled.

When the enigne is cold, you are in what we call "open loop" meaning no emission control.

Get the thermostat installed first. Make sure it's the same temp rating as the one that's in there. Either 180 degrees or 195 degrees.

Then you should pass.

SMOG TEST


If it was originally intended for Texas, it's probably been made as a 49-state-compliant vehicle (CA has stricter emissions). To pass in CA, you may need some new parts for the truck in order to get it to pass. Or you may find that the best course of action is to sell the truck and buy a CA-emissions car.

The CA DMV may well have information available on how to get non-CA-compliant cars to pass the CA emissions testing.

2000 chevy silverado z71 check engine light will not go off.


you have to know what the code is that your truck putting out your truck has 4 O2 sensors. the trucks computer is smart and the code will tell you witch one is bad but if you replace just one the next one on the same exhaust pipe will probley go bad so its safe to replace all four. the draw back to replaceing all of them is thay cost about 80 bucks for one ACDelco O2 sensor. It has to be done before it will pass Emissions. not a hard part to change about a 7/8 open end wrench will take it off. have fun.
