A nonfunctional car heater is one of the more signs of the presence of air pockets in the coolant system. When you turn the car heater on, no heat will be coming from the vents. Due to the air bubbles, the air could not be pushed out. The trapped air prevents the hot fluid from running into the heater core.

Leaks not only prevent coolant circulating but also let air into the system. The presence of air within the cooling system causes 'airlock' to occur, and as a result large bubbles that cannot be pushed through the system materialise.

If a valve is expose on the upper heater hose piping crack that open only when the engine is warmed up for at least 15 minutes. If no valve is seen you will need to loosen one of the heater hose clamps ever so slowly to let the air out. The process to loosen the clamp is not recommended unless you do this first.....

Assuming you have already filled your cooling system with the proper G12 coolant to the cross-hatch level, open the coolant overflow/fill bottle cap. Leave it off. Start the car and let it idle. Turn your heater on full hot and full fan speed. Let it come up to temp so the thermostat opens up and allows coolant to flow through your system.

blast the heater matrix with hose pipe to push any crud and air out. then i fill the system as best i can via the reservoir with the small pipe off.
brutusmotorsport New Member
also once you topped up the water, when you start the car you must open the vents and stick the heater on max and hot, this allows the air to flow and will help no end with an airlock.

The cooling system on a 4.6 is self bleeding as far as now, if you got trouble with air locks you will most probably find the small bore pipe from the top drivers side corner of the rad to the expansion bottle is blocked, or the expnsion bottle connection for this pipe, remove the expansion cap when the engine is running, but not hot, and you should see a constant stream of coolant running into the tank from that pipe, this is how any air in he rad vents out, if the pipe is blocked you will get a build up of air in the rad and temp will go up!!.
gavbriggs Well-Known Member
as he said above but if you take the pipe off the rad, with engine off, you can blow down it and, obviosly, bubbles should appear in the tank.
