    Radiator leak

    Has anyone here had a problem with their radiator?

    Coolant was all over the ground a couple days ago. Sensor kept saying coolant low so i put more in and didn't leak for 3 days at allThen 3 days later coolant sensor came on again, and coolant was all over the ground.

    Took it to a shop here in North Dallas (Kwik Kar),
    and watched the mechanic pressure test it, but nothing came out. I had them replace the radiator and this morning coolant is all
    over the ground again. The work is under warranty and the mechanic claims that a seal in the new radiator wasn't right and they
    are going to put another new radiator in no charge.

    My question is-Has anyone else had radiator problems at all?

    Re: Radiator leak

    The GM OEM radiators are a known weakness and the aftermarket units of the same design are not much better. Many on this forum have gone through several, although most are not "dead on arrival." The permanent fix is a aftermarket aluminum unit http://alradco.com/index.php?option=...d=54&Itemid=60. Finally, in your case, I am not sure the water pump can be ruled out.

    But oem is junk and will fail eventually. Get the Alradco and be done with it.
