Hi.
Had a nightmare today. Went to change my daughters antifreeze and as I was bleeding the system the bleed valve on the heater hose snapped off. I managed to temporarily run a self tapping screw through the sheared off head into the remaining part of the screw in the housing and used plumbers sealer to at least get the car mobile. It seemed to work, at least for the moment hopefully anyway.
I then refilled the lost coolant and bled the only other outlet on the radiator then put the expansion tank lid on and started the engine. It took about 20 minutes before the fan came on, the heater blew out hot air and the top and bottom hose became hot. So far so good. I let the car cool a bit and topped up the coolant. I then restarted the car and let it run for another 20 minutes or so but this time the fan wouldn't come on and the top and bottom hose felt soft and didn't get hot.
I took the car for a run and the heater continued to blow hot and the temperature gauge stayed where it should in the middle. When I opened the bonnet the hoses were still cool and soft.
Am I imagining there is air in the system as the car is running fine? If there is air how can I get rid of it?
Also when I replace the broken heater bleed valve is it, like I suspect, one whole piece connected to the four hoses and is it easy to replace?
Your help would be much appreciated.
Thank you.
