Generally, it attaches to the radiator where the radiator cap goes, and you pump it by hand until the pressure on the gauge matches the pressure that is written on top of the radiator cap. Typically on a modern vehicle this pressure is between 13 – 16 psi. Let the vehicle sit with this pressure for 20 – 30 minutes.

What causes pressure in the coolant system?

Hot air expands. The cooling sysem is basically a sealed system which heats up thus any air trapped in it will expand. The reservoir stores excess coolant and the trapped hot air hence the pressure. Also remember the higher the pressure the higher the boling point of water.

How do you know if you have air in your cooling system?

Squeeze the upper radiator hose to get out any remaining air bubbles and top up the antifreeze if needed. Change the cap, bring the vehicle down, and take it for a spin. By this point, your vehicle should be free of any air or air pockets in the system.
