ah has me stuffed .. i can get a flow out the heater in let line but it doesnt make it back out .. have conected a hose to the inlet and disconnected the out let and get a full flow, i can only guess the pumps are not really desinged to pump water all over the place , im thinking of disconnect the manifold jacket to see is that aid curculation .. have not changed out the water pump at this stage , cant be stuffed ..
look like the only answer is fit air con and move to sunny QLD
hmm maybe a little in line electric pump will get it moving .. lol
and it was as i 1 st thought just plumbed the wrong way ..
see pic attached once i swapped the return heater hose form where the manifold hose is now all worked a treat im please i didnt swap the water pump ..
