    I heard that its better to use distilled water in your raidator than tap water. Because of all the minerals that the tap water could contain. Those minerals would than deposit themselves inside my cooling system amd that might be bad /forums/images/graemlins/smirk.gif... Of course i've allways used tap water but now that i've gone through all the work of replacing the water pump and redoing the intake gaskets i want to do it right.... /forums/images/graemlins/thumb.gif /forums/images/graemlins/thumb.gif

    yeah, what he said, distilled water is just that, water, tap water is chlorinated fluoride-ified water...the purer the better

    tis true! Most people overlook this. The white stuff that it coated around the cooling tubes is the calcium that seperates from the tap water. I used distilled water and coolant when I filled my truck. Texaco make a red "long life" coolant thats premixed with distilled water. This is required for detroit diesels.

    When I bought a new radiator for my S-Jimmy last year it came with directions that stated that if it was NOT filled with just coolant and distilled water, then the warranty would be void. The calcium deposits from tap water are the main cause of clogged tubes in the radiator. /forums/images/graemlins/frown.gif

    But if you only changed the water pump, then there is still quite a bit of the old stuff inside the block. You need to pull the drain plugs on each side of the block to get it all out.
