Sounds like the thermostat is sticking.

Re: 2004 gmc envoy
How's the coolant level? Does it do it when idling or when driving or both?

Re: 2004 gmc envoy
I'd suspect thermostat. Mine was doing the same thing and continually got worse until I changed it out.
Also, I'd check to make sure the fan is working properly, that the radiator is cleaned out, and that the water level is full. |
