    Noticed antifreeeze bubling out where green circle is, in the corner. The pic is behind water pump (driver side). Question is ..Is this a spacer behind the water pump??(white arrows). The bolt in the picture above is to the water pump.

    The water pump is mounted to a plate that bolts in between the timing cover and pump. You have to remove the pump attached to this plate to get to half of the screws that come in from the back. This means you have 2 layers of gaskets to leak/seal.

    If you are going to replace the pump or at least the gaskets, now would be a great time to plan on replacing the timing chain set if you have over 100K miles too.

    my 6.2 leaked from the same exact spot, all i did was remove the PS pump bracket, and tighten the nut. now she doesn't leak at all and i didn't even use sealants.

    Be very careful with this approach. I cracked a water crossover housing in the middle of nowhere (Wyoming) on vacation once trying that meathod to fix a small leak :doah:

    It wasn't like i just torqued it down, the SOB was very loose, like 4 water pump bolts were hand loose, along with a 10 other bolts on my engine. my truck seems to vibrate it's self apart.
