The radiator was replaced and everything has been fine up until it just started to do it months after the replacement.

My car is going into the body shop tomarrow to wrap up all the loose ends from my new paint job. I'll stick around my car as it warms up just to see if the fan actually turns on (I don't think it does). If it doesn't, I'll replace the relay and go from there as the wiring and connections still look fine.

Hopefully it's just the low speed fan relay and not the fan itself. Even if it is the fan, all that means is itll be replaced by a higher CFM fan anyway.
