RE: 2000 Silverado Overheating
I replaced the fan clutch but the problem was still there. Talked to someone at a Car-X since the dealerships around here refused to answer any questions over the phone or make any suggestions. He said to check the temperatures of the radiator at the top, middle and bottom.
I used a temp gun, top was 190, middle 189, bottom 120. I replaced the radiator and works perfect now. Pulled my race car on Friday night, air on high, never got above normal operating temperature. Thanks for the help guys. Hopefully, this will help someone else in the future.
By the way, Autozone charges $250 - $350 for the radiator. Dealer - $550. I got one at Smyth Parts Plus in Cincinnati for $150. Just in case anyone else is in the area, they sell all radiators pretty cheap.
