I do realize this topic has been beat to death......but I am having no success in doing it this time. Normally the front end higher than the back and filling the system let the air out of the vent. Drive and repeat a few times and it works.
In this case after replacing the water pump, both the thermostats, hoses and the heater valve (it was leaking). I also flushed the heater core both direction, confirmed the operation of the heater valve.
500 miles of front end higher and venting (both hot and cold engine), The car is running hotter and there is no heat out of the hvac. So air pockets right ?
One more data point the temperature gauge does not the fluctuate just climbs to the second white line. I am used to seeing it at the first white line.
The only difference in the lay out is that I moved the heater valve up so it was easier to see and get to. It is still below the vent point.
I have also tried the "using a pressure tester to fill the system" same results.
I am about to try the vacuum the system the system and then fill it with the vacuum drawing the coolant in.
Any insights would be appreciated.
Thanks Sox
