    Default Plastic radiator tank

    Does anybody know where i can get a replacement radiator tank. Most places want to sell the whole radiator but I only want the tank. It's the driver side tank for a cross-flow radiator for a 2001> C/K 2500/3500 HD with the 8.1L gas or both sizes of Duramax diesel engines and the Allison trans. I have a brand-new radiator but somebody somewhere in a warehouse dropped the carton and it landed on the lower vibration cushion and ruptured the bottom around the mount. We didn't find the defect until coolant was added and began pouring on the floor. I checked with somebody who welds plastic and they wouldn't touch it, said the ABS crumbles and wouldn't hold especially under pressure. The tank must have the large fittings for the oil cooler lines (1/2") to work.
    Thanks, Richard G

    I tried replacing a plastic tank on my wife's old 92 S-10 Blazer few years back. I bought it from Oreily's. I couldn't get it to go back in correctly, so I ended up just replacing the whole radiator.
