    Exclamation coolant leak...

    The last time I had my 2000 Silverado (4.3 Litre) in the dealership for some work, I was told that my lower intake manifold gasket was leaking. they said it is a "very slow" leak. Is this something to be majorly worried about? I have done majority maintenance/repairs on my truck myself, but I don't think I should try this one. Is it as simple as putting in a bottle of leakstop? Or should I have the gasket replaced? Or just leave it alone?

    Thanks,

    OkieMike

    You will want to do intake gaskets, really it isnt to bad of a job. But never ever ever put stop leak into the radiator, unless it is a last resort to get you home out of the woods.. And then you will want to flush it immediately. It will clog up your entire system.

    Like all said on the stop leak.I carry it when on a long trip as a just in case-limp home measure.
    It probably works best when the hole is in metal-like an old beat up radiator in an old motor you plan to switch out soon.

    I had just the sort of leak you describe-it was leaking toward to back-to the outside-dripping backwards.

    Don't delay too long on the repair-check your oil and coolant frequently if you delay-look for cloudy "stuff"
