Hi Folks. I need a little help identifying part with round top to left of the radiator. (see pic) Recently rear ended somebody and mashed in the radiator wall. Now car overheats after 5 min of driving. The part to the left of radiator was smoking last I tried to drive it and when I tried to blast hot air, only cold air comes out of the vents. I'm going to try to swap the radiator, fans and unknown part myself. Don't want to junk the car, engine is great and frame alignment is fine. Any help or tips would be great. Thanks!
