What causes an airlock in hot water system?

Airlocks happen when air is trapped in the system. This air forms a blockage which gets in the way of the hot water as it makes its way to the taps or the central heating system. An airlock in the hot water system will prevent water from coming out of the affected tap.

What should I do if I have an air lock?

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.

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.

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.

Why does an LS engine need an air lock?

For example, in an LS engine, the head is higher than the pump (outlet) creating the need for the bleed lines on the cylinder head. Normally the OEM will have a specific bleeding procedure to follow eliminating the air. The simplest remedy for an air lock is cycling the system.
