“My truck radiator started to smell as if it had a leak. I took it to a radiator shop. This shop happens to be very close to the GM plant in dayton, ohio. The man took one look at the truck.

He said they had been left outside for a period of time and all of them had to be cleaned out because of heavy rust. He stated mine must of been missed.
