can you tell me the easy way to get the air out of my pressurized heating and cooling system??
i tried everything to get heat i replaced the therm. the hoses the heater control valve rad. had a rad.service done and im still convinced i have air in the system???
run your motor till warm (stationary) with the radiator cap off or expansion tank depends on the age of car wait for the water to expand 3 times which means letting the water raise to the top of the filler cap it may overspill the replace cap this will expel all air locks hope this helps :)
you need to remove upper rad. hose at t-stat housing. fill plastic tank till you see coolant comming up t-stat housing. then put hose back on....should be good to go....
