What is your question?
My 2004 GMC Envoy keeps overheating. I have replaced the water pump, radiator and cap and thermostat. As soon as I drive for a far distance or am stopped in traffic it gets hot. The Reservoir will bubble like a volcano ready to erupt. What can be causing this???
What makes this problem better or worse?
It's better when the engine is cold
How long has your 2004 GMC Envoy had this problem?
A few weeks

Hello, the first thing I think about is that after you replace so many components of the cooling system, you need to make sure that any and all air is purged from the cooling system. If not, you will get air pockets bubbling up and boiling over. Once you ensure all air is purged from the cooling system, then you can turn your attention to engine temperature as it's measured, checking cooling fan operation, coolant flow and so forth. www.repairpal.com/repair-shops Using that link you can find a shop near you.
