Hey guys, first post here hoping to get some help troubleshooting my new
(to me) westy.

I received the gowesty coolant pressurization pump this week and today went
to test it out. I tested the cap, it passed. Then I followed the
instructions for checking for leaks and pressured up the system to 20PSI.
BOOM, a leak sprung at one of the junctions between the plastic coolant
pipe and rubber hose, the one at the rear that does not angle up.

So I drained the coolant using the shop vac technique (removed the radiator
bleed screw and sucked as much coolant as I could out the pressurized
coolant reservoir).

Then I installed 2 new hose clamps around the leaking junction.

Then I refilled the system and bleed it with the pump according to gowestys
instructions. It took 2 gallons of 50/50 mix which is roughly about what I
was able to suck out. I think probably 2-3 gallons is what was taken out of
the system between the leak and the shop vac sucking.

Now after starting and letting warm up the overflow tank is REALLY full and
the van got up to half way up the temp gauge from 10 min of idle (its never
been more than about 1/4 of the way up before.

Any ideas?
