Explain in detail how to replace a windshield washer reservoir in a 2000 Chevy Tahoe w/4.8L.

Welcome. To replace the reservoir on these is not difficult. It will require removing the left front tire and inner fender.

    What is the most cause for the reservoir leaking and is the 99 Tahoe similar to replace because I have one that leaks also.
    A 99 is similar to replace. It could be a cracked pump or casing, it could even be a bad line. I have seen these lines fail a few times.

    In essence, what you're saying is to remove the inner fender and see what's actually leaking before buying the reservoir. In removing the inner fender, which I've never done, is it just a matter of a few bolts to remove and replace?

    The use plastic push pins on the 2000, but the 1999 is much easier. IF you take the battery tray out you can see what is leaking from there.

    The sides of the base of the pump had cracks in it which allowed the water to drain down to a point below the cracks. Your removal procedure was great-was able to follow your directions-wish more info like yours could come from other advisors-THANKS.
