I understand that the
bottom of the tank should have a hose
running to the top of the water pump, and I have installed a fitting just
underneath the thermostat for this. Where would be the best place
run/connect the hose that connects to the side of the expansion
tank?
Hi
Paul,
You want one fitting on
the engine at the highest point you can, which also has pressure from
flow. That connection goes to the fitting that's on the side of the
tank. The other connection will be on the suction side of the radiator,
such as that port that you had on your water pump housings lower hose.
That hose goes to the bottom of the exp tank.
You set up a flow
between these two points. Water flows from the high pressure point (at
your thermostat housing) in through the side of the exp tank, out the bottom of
the tank, then back to the lower radiator hose. The idea is that the high
point may have pockets of air which get forced out (the whole idea). When
this hose goes into the side of the tank, the air goes up, and the coolant stays
in the bottom. What returns from the tank to the engine is all coolant
since it comes from the bottom of the tank. You don't really want big
hoses, since it's just moving some air bubbles, and the flow is bypassing the
radiator.
Did that
help?
