I checked the coolant level today and it was below "low". I've only had the car 5 months so this seems strange to me. I did put the STi radiator cap on, but that's it so far as far as mods go. Can this cause a leak that I think is happening? Another thing, I hit a deer about a month ago, and it did about 5k worth of damage, messing up the front passanger side of the car. I got it all repaired and the shop didn't see any engine damage. Is it possible the radiator itself took some damage and is leaking very slowly?
PS: not sure if the deer died as I drove back to the "scene" and the deer was gone! I hit it doing 45mph too so if it did survive it probably wasn't for long. I'm hoping it died, or a wolf or coyote got it
