    I've got Mopar hoat now, refreshed recently. My water pump is seeping a bit so I'll be replacing that very soon. Question is how well does the zerex go-5 mix if I decide to telling with it? Is a flush suggested if I'm switching coolant brand? Thanks

    Mopar and zerex g-05 are chemically the same, just different color.
    You will be just fine, even better with a new pump to boot.

    That's what I was thinking, thanks.

    So as I said earlier, my water pump was seeping, so I ordered a reman from Napa. Then of course it dried up and has remained dry until this morning there was a little puddle beneath the Jeep and a bit on top of the water pump behind the pulley. Is this an expansion / contraction thing or should I be looking elsewhere for a leak?
    Thanks

    The coolant is probably seeping out the weep hole in the water pump. This is what mine was doing for a year before I replaced it. No more coolant loss.

    That's what I figured, just thought I'd ask the collective mind Incase I was missing something.
    Thank you one and all!

    The Napa WP reman should be okay. I ran one for 80k before it started leaking again. Got 80k from it versus 108k from the Mopar one. Not a huge difference. Could've been reversed.

    Replaced my water pump last week because of the same reason. Coolant coming out of the weep hole. I used Zerex G-05 and the only thing negative I can say about it is that I can't see the level in my coolant tank! I mixed it properly and also checked it with a hydrometer. It is good for -40 degrees Fahrenheit.
    Why did they put the weep hole on the top of the pump shaft housing?
