Chassis heat problems

[sfedeli3]

Hi Don,

I know that you don't want to hear this- but it was the one that
you're talking about on the bottom of the water pump that failed on
mine. Replacing the innards is a good move- and should solve your
problem. Some plumbing supply houses may carry new gates and seals for
the valve, but good luck finding a perfect match. Sadly, I do not
think that there is any way to replace that valve without having the
water pump off- and that is a challenge in itself. Maneuvering a 25 lb
chunk of iron with fittings and trying to match up the drive gears was
a real PITA.

isn't much room to wrench. Had to drop the air conditioning pump down
to have room to turn the right-hand one.

there was another valve below the water pump - black with grease, and
hard to see - even harder to get to. It wasn't until I came back to
your post, Shane, to make this post that I happened to read new
meaning into the "I've replaced 2 of the 4 valves with ball valves." I
assumed you meant 2 gates, 1 Sporlan, 1 Bosch, which is what I knew I
had; now I'm thinking you meant 4 gate valves. Am I missing a 4th gate
valve somewhere?

valve out without removing the water pump, which I really don't want
to tackle.

thing in its own right), and replace the handle/stem/gate with the
best of the other two. You can see it here after replacement, as well
as the handle of the left-side ball valve:

one from below the water pump. The threads are just eroded away enough
that the gate will slip somewhat freely on the stem.

filtering 8 gallons of collected coolant for replacement, then
checking for leaks, etc.
