Please dont hate, just trying to get something straight. Is the smaller radiator in front of the main coolant radiator for ac? i was in a front end crash and it wasnt really damaged but its kind of in the way, and i dont have ac so i was wondering if i could just take it off? i thought it was an oil cooler but thats starting to seem illogical

 

A/C Condensor coil.
The oil cooler is the long small one in front of both at the bottom.

 

Go google "rx7 fsm."

It will help you beyond belief!
