2005 vw passat how chek woter pump work or no
how do you get rid ov a air lock in the cooling system on a vw passat 1.9 tdi 2000
If you are talking about a 1998-2005 Passat there is a bleed hole in the cooling system for this purpose. The heater coolant lines pass through the second firewall remove the clamps on the lines and pull them toward the front of the car about an inch. One of the lines has a little hole for bleeding the system.
The air corn on your passat is not cooling for any number of re sons, linkage problems, one of the mechanical parts is broke but the more than likely reason is the system needs recharging. You mite even have a leak in the system. Take it to a garage you trust ( You can't recharge or check for leaks at home).
Engine cooling system is not a closed system you can't remove the air.

Air bound means that there is an "air bubble" in the cooling system that is preventing coolant from circulating in the cooling/heating system. (air can be compressed fluid cannot)
You may have air pockets trap in the cooling system.
COOLING SYSTEM OF WHAT ??????????????????????? Most auto parts stores sell cooling flushing kits. Get one follow the directions and it should take the air out of the system. You must remember that your heater is part of the cooling system as well as the cooling for your transmission.

If the pump never shuts off there may be an air leak in the system, or maybe a sensor could be bad or disconnected. I don't really know if locking system uses pressure or vacuum (I think vacuum). All the locks (doors, trunk, gas tank filler door) use this pneumatic system. On the models I have owned it has been reliable.
The Volkswagen Passat has front, side, and rear air bags. It has child safety locks for the windows and doors. There is also noted an emergency release trunk button.
If the cooling system is in good working order the system will bleed the air out itself. If the system has a leak anywhere no matter how small the system will never bleed the air out.
