Asked by Idkjustaskingaquesti... Sep 05, 2019 at 11:13 PM about the 2008 Chevrolet Equinox LS AWD

Question type: Maintenance & Repair

I have a 2008 chevy equinox that i just had the
heads and water pump replaced. Today I drove my
car to the store and while I was waiting for my wife
the temperature gauge acted like it shut off, the air
conditioner started blowing hot air and then the
car gave me an alert that the engine was hot and
to turn the A/C off.

The fans didn't kick on like they did before we
replaced the pump and heads. And that also
doesn't make sense to me
I've been chasing this issue for 6 months and i
cannot seem to find the problem anyone have any
ideas?

Also I forgot to mention that the temp gauge read normal until I noticed it on cold right before it gave me the Hot engine warning.

Did a shop do the heads and water pump? If so, take it back and ask them what's going on. If this was a DIY job, then start by checking if and when the fans are coming on. If they're not coming on as they should, then check performance of the engine coolant temp sensor. There might be two sensors, one is a sensing unit for the dash gauge and the other operates the fan controller. There could be other things going on but the ECT sensor is a good a place to start as any.
