2005 gmc envoy overheating when engine shut off


Sounds like your electric cooling fan is not turning on. Check the fuses and relays associated with the fan circuit.

Had a flat tire,reduced engine power light came on


Either the tire pressure monitoring system detected excessively low or zero tire pressure and the computer has been programmed to set the vehicle into limp mode when that happens or a wheel speed sensor or another sensor detected an issue when the tire deflated and the computer sent the vehicle into limp mode.

One way or the other, once in limp mode there would have been fault codes generated and could have be read with a scan tool. They have probably cleared now.

After replacing the fan clutch and water pump do i have to reprogram the computer on a 2003 gmc envoy?


No! there is nothing to reprogram. The sensors in the coolant system and the temp sensor for the fans dont need to have anything done to them. If you are not getting any check engine light, you are good.

Maybe time for a throttle body cleaning, make sure both the front side and back side are cleaned thoroughly. Also disconnect the battery while doing the cleaning, this will reset the computer and allow it to relearn to the cleaned throttle body.
Do you mean a whining sound? Does the sound change if you turn the wheel to the right or left? If so, it may be a front wheel bearing.

Well the first mistake you did was not take it to your GMC car dealer and let them check it out. It could be a computer problem inside the dash somewhere. Hope this helps!?
