    Default gm leak tabs on 5.7 intake manifold leak

    Hello, I wanted to know if I could use the GM stop leak tabs on 5.7 intake manifold leak.
    Just untill it warms up outside to do the job right with the new gasket.
    Thankyou Raceville

    I wouldnt reccomend using any type of stop leak, since it is a get you home method, that over time can clog up your radiator, and heater core, and just leave behind a lot of junk in the coolant passages, that you dont want. Also when you change your intake gaskets use green coolant instead of dexcool.
