The Heater core was toasted after the first owner's attempt at an in-car soccer gameor something, so I pulled the entire assembly, and called Al's for a rediculous replacement charge of about $100, I told him He's crazy If he thinks I'm going to buy a heater core for that much (with some 4-letter's of course). Jumped in my pick-up, and in about an hour Walt's Radiator had it fixed in about an hour for about $30, and I had everything reassembled in a few minutes with a coat of paint.
