Relax, for that bleed valve will be fine not opening , many early system vans now don’t even have that valve, just straight joiner to the metal crossover pipe and a bung in the other one , or a "Y" joining all .
You will be able to bleed fine as it is as long as it’s not stuck open.
Just raise the revs to about 2000 , top the header tank up to the brim , and open the rad bleed bolt , and keep pouring water in the header tank so it’s level is always full to overflowing .
You do need the heater on hot from the start til the end , and when you are long longer getting air from the rad, close the bleed bolt , top the header tank up to the brim put the cap on, then reduce the revs to idle . Give it 2 mins and switch off , go make and drink a brew . Come back in ten mins and open the rad bleed valve slowly and if coolant comes out but not air it’s pretty much bled .
That's interesting. When the head gasket failed, I noticed that pipe didn't get hot and thought it was the thermostat. Looking at the diagram it must have been a blockage in the rad. I'll need to have another lookMocki wrote:yes, the thermostat is on the other end of the head , and the coolant that has been cooled comes from the rad back
