Cooling System Pressure Tester
A cooling system pressure tester pressurises the cooling system with a hand pump to find leaks and test the radiator cap.
What is Cooling System Pressure Tester?
Adapters fit different expansion tank and radiator necks. A falling gauge without visible leaks can point to a head gasket. It also checks whether the cap opens at the right pressure. Combustion gas test kits can be used together with it to confirm a head gasket leak.
How it works
Pumping air raises the system to its working pressure so leaks show up as drips or falling pressure.
Why it matters for your car
Test with the engine cold and never exceed the rated pressure. Hidden leaks may only appear when the system is hot.
