This tool attaches to the top or the radiator or coolant reservoir and enables air pressure to be pumped into the system including the engine block, cylinder heads, coolant hoses, heater core and radiator. Diagnose leaks efficiently how to test a cooling system for leaks like a pro if your vehicle is losing coolant and you don’t see any obvious leaks, you need to take a methodical approach to diagnosing the problem. Learn how to effectively pressure test your vehicle's coolant system to catch leaks early and avoid costly repairs To do a radiator pressure test, you’ll need a radiator cap tester adapter, a hand held vacuum pump, and a pressure gauge First, make sure your engine is cool Then, remove the radiator cap and screw on the radiator cap tester adapter
Pump the vacuum pump until the pressure gauge reads about 15 psi If the pressure drops, then you have a leak How do i pressure test my cooling system at. Detecting a coolant leak can be a challenge but doing a pressure test can help you find the source of the problem Master trainer gary kimball demonstrates how to conduct a cooling system pressure. A test tool pumps air pressure into the cooling system to simulate conditions when a heated engine expands coolant and builds up pressure
