How do I get rid of an airlock in my cooling system?
The simplest remedy for an air lock is cycling the system. Start the engine run it up to temperature, shut it off, allow the engine to cool and repeat as required. Normally 1 or 2 heat cycles will show the level change and topping of indicates the air has moved though the system.
Why do I keep getting air in my water pipes?
The main cause of air in the water lines is water system maintenance. Cutting off the water supply for a period of time can allow air to enter the system. (Running faucets briefly usually resolves this problem.) Maintenance work on the water main may also introduce air into your system.
Can you get air in your coolant system?
Causes of Trapped Air in Cooling System If the radiator cap fails, however, coolant may escape and air may enter; thus, leading to trapped air in the cooling system. In addition to a bad radiator cap, other possible causes of trapped air in the cooling system include the following: Leaking radiator hose.
Where is the air lock on a car heater?
Located in the cooling system, more commonly in the upper hose, heater core or thermostat (highest points of the system). A common air lock normally shows up as higher coolant temperatures accompanied by low or no expansion. In some cases the heater will not function correctly when engine is at operating temperature.
Why does my car not have an air lock?
In some cases the heater will not function correctly when engine is at operating temperature. The air pocket will create a hot spot and low levels of coolant will decrease efficiency. Some engine designs have a specific problem with the way the coolant passages are designed or located making it more difficult to move the air out of the system.
How does air move through the air lock?
Start the engine run it up to temperature, shut it off, allow the engine to cool and repeat as required. Normally 1 or 2 heat cycles will show the level change and topping of indicates the air has moved though the system. If replacing the thermostat drill 1 or 2 1/8th” holes to allow the air to easily move though the thermostat.
