Default 05 overheat

My 05 rs, lost control yesterday in the snow/ice, and popped a curb. My wheels are slightly out of alignment, but that's not the issue. The issue is that my car is overheating ever so slightly. Its happening at low speeds and when sitting still. Cruising doesn't seem to have a problem. Anyone have any ideas as to what's causing the overheat?

I would think that it is a problem with the fans. Check to make sure they are both turning when it is hot, and check the connections down at the bottom on each side. You may have broken a wire or something.

So after 2 weeks, I've had no problems, and its been cold so I've had heat/defrosters on all the time. but Tonight I got a little warm in my car so I turned the defroster/foot heat off and came to a red light. I was talking to my friend in the car next to me, and I looked to see my temp rising. I turned the heat and defrosters back on and it stopped climbing when it hit the 3/4 slash mark. Once I started to accelerate again the temp dropped back to normal so I drove with the defrosters on all night again and it didn't happen again.

Radiator cap isn't getting pressurized. Fans come on when it reaches temperature. Did a leak test, not leaking. My head gasket appears to be leaking oil.

This all started after you popped the curb? Did the curb have snow piled up on it that might have flattened the fins on the radiator or condenser?

First, you have a head gasket leak which might be the result of overheating... (and in that case, possibly warps heads) In any case, your overheating is now a minor problem....

But on your coolant issue, define 'leak test'. Do you mean pressure test? If the system holds pressure, there is 100% no way that it can NOT build pressure at the radiator cap, assuming the cap itself isn't bad. When liquid heats up, it expands. If you have a sealed system that passed the test, it builds pressure. No way around physics...

Correct and not that I can see. I noticed today that the car does it every once in awhile, not every time the heats off. I'm thinking it is air in the system since its not all the time, but idk how it got there
