Plastic radiator repair

I doubt you can actually fix it "yourself", but you can save lots of money by taking it to a radiator shop instead of buying a used or new radiator. They can replace the plastic tank for the bad side, but it is usually the drivers side because this is where the hottest water exits the engine and causes the plastic to crack. I removed the radiator myself and took mine to a shop and they repaired it for $40........cannot repair yourself because the tank has to be crimped on!!!! And radiator "stop leak" products will not work because they are for metal tanks!!!

Yes a radiator shop may sell you a new tank, some will, the dealer and parts stores only service the whole radiator, as far as plastic welding the crack, it's a watse of time, works for awhile and then cracks open again, have tried it several times.

You can try a plastic weld but they usually dont hold up very well on radiators --a radiator shop verse junk yard even cheaper is a u pull it yard
