Radiator broken or just really hot weather?

I believe the head gasket was not an issue on the 2.2 ecotec which he has (2003+ and some 2002)

Relay yes. Replaced a couple

So I did a few tests yesterday during the afternoon commute.

1. I turned off the AC.

When I kept the AC off, temps didn't go past 110. It fluctuated between 95-105. The cooling fan did not seem to get engaged. It was a bit windier than usual, so that may have helped drive air in.

2. I turned on the heater to the bottom vents and opened the windows.

Temps looked like it dropped a few degrees. Not a large drop, but at least it didn't keep the temps from increasing.

So, it doesn't look like a radiator issue? And moreso due to a combination of heavy AC usage and hot weather?

Right. The 2.2 was the chain tensioner right?

Could also be a thermostat.
Won't be tstat as those are designed to fail open. My guess is water pump is on its way out. OP check under the car to see if there is a puddle of coolant. If so its most likely the water pump.

Won't see coolant. Probably dry off before it will drip as engine is hot. Look for residue from it. You will see it if it's leaking.
