El conector Quick de esta unidad funciona en casi todas las marcas de tapas y adaptadores de prueba del sistema de refrigeración. El medidor integrado muestra los niveles de presión comunes para diferentes sistemas de refrigeración de hasta 30 PSI máx. La herramienta proporciona una presión constante sobre fugas para rastrear su fuente y llena sistemas de refrigeración aún más grandes casi al instante.

Works great! I love having this it makes diagnosing cooling system leaks so much easier. Also saves a lot of time verse using the hand pump testers. Highly recommend.I have a Matco tools master cooling system tester and this works with it, Uses the same fitting.

This is excellent for pinpointing coolant leak very fast due to the constant pressure it puts on the cooling system. Even the lowest psi from this will pinpoint a coolant leak very fast, which is just what I needed.

I used this tool to find an hard to find coolant leak on a Ford vehicle with rear passenger side HVAC unit (second evaporator and heater core units). These are common on many full size pickup trucks and large SUV’s. In my case, the rear heater core was leaking slowly simply because the 2 hose clamps rusted out and could no longer provide a leak-proof seal at the hoses. The small puddle of coolant was first misdiagnosed as water condensation from rear evaporator core (summer time repair).This tool gave me just enough pressure / 15 psi with shop air to slowly follow every single engine cooling components with a flashlight and find my smoking gun! Being able to concentrate my attention without constantly pumping up pressure was a real benefit. For those of you who have internal water pumps on Ford 3.5 V6, this is a great fast way to find out where your small coolant losses are coming from. It’s too easy to point out and condemn the water pump when it’s not the real issue.Tool itself feels solid. The gauge is precise and protected by some rubber on the outside. The only thing i would like to see improved is the ball valve. It feels flimsy. I don’t believe it’s worth removing a star for that.

Connect one end to your cooling system. Plug in your air line, set the PSI to match the PSI on the cooling system you are working on and let it build pressure. If there is a leak this will find it quick instead of pumping the manual type cooling pressure tester for minutes at a time. Works great!
