I put my car in the shop for evaluation of a problem which was diagnosed as the fuel pressure regulator. I had no other problems with the car - at all! The day after the repair the radiator starting pouring out the coolant in a big way. I can't travel more than a couple of miles before the reservoir is empty. I can't help suspecting they damaged my radiator but I have not confronted them. Where is the fuel pressure regulator located on a 1991 Chevy Cavalier (is it near the radiator?) I would understand a small leak that got bigger and bigger over time, but this was sudden and drastic. Need help big time, it's very expensive (to me, anyway) to replace a radiator.
