Could have a plugged catylitic converter

Ldavies22, did you ever come to a conclusion with your 08’? I just bought an 08’ equinox about a week ago (person to person purchase) and the last 3 days it has been getting hot. Thing is, I have no codes registered on my dash except stabilitrak and the water pump is fine, radiator seems fine, plenty of fluids, no milkiness, no mixture in the oil, has full power when driving or taking off, new thermostat, and new EGR valve. We are at a loss..

Catalytic converter is plugged, temp sensor is bad, you have vapor lock, or the radiator is full of pollen and/or other debris. Ex. bugs, dirt, mud etc. Lightly spray your radiator fins with water from inside to out with very minimal pressure at all preventing bending and mashing of the fins. They are very delicate and bend really easy so be really careful what angle you spray at also. Let me know how it goes
