Never compromised on quality, fully equipped with state-of-the-art technology – Designed with the user optimal experience in mind. International Renown, constantly modernizing powerful devices to meet the demands of the modern user.
Pressure regulates shop air to test any cooling system or radiator cap for leaks
Quick connector works on nearly all brands of cooling system testing caps and adapters
Fills even large cooling system almost instantly, and provides constant pressure on leaks to trace their source
Gauge displays the common pressures levels for different cooling systems and regulator will max at 30psi to prevent damage
Customers say
Customers appreciate the electromechanical gauge’s functionality, build quality, and value for money. They find it works well for pressure testing and draining cooling systems. It takes about one second to build pressure, and they can slowly release the pressure so they don’t blow coolant all at once. The gauge is well-designed and comes apart easily under pressure. Many customers find it easy to use, with good cooling system performance and air quality. However, opinions differ on leak detection.

Great tool
This is so much easier for systems that have major leaks, you can easily search for them while the air compressor does the air control, only goes up so high in pressure due to the regulator, less then 30psi. Doesn’t come with an air hose fitting atleast mine didn’t. Great value and build quality, you can also change the hose end to another style if you don’t have the quick attachment kinda. Other Amazon sellers have some great kits with quick attachments to go with this item.

Does the job
Extremely budget friendly, attached the positive fit hose to this for Detroit and Cummins cooling systems. Works great and will be my backup

Click and turn
This is one of the best pressure tester. Click the air line on then turn the the inlet valve till you get to the pressure on the cap turn off and check check for leaks

Wish I’d bought this sooner.
My only complaint is the attachment it came with is a 2 piece unit with the cone and a piece that goes inside the cone. It comes apart easily under pressure. I have one of the ” master cooling system kits ” with a bunch of adapters to fit different radiators etc, and those all fit this. It’s so much easier to pressure test with regulated air than with the hand pump. I’ve also used this to assist in draining and flushing of the cooling system. It works great.

Uses shop air power
Worked great- much faster then hand pump. Able to find the small radiator leak right away .

Only hook up to certain cooling system testers
Very helpful when filling cooling system. Can leave system pressurized to find the leak before all the air is pushed out of the system. Keep hand pumping gets tiring and annoying

Must have
Works great. Back off regulator and attach shop air. Open valve and adjust regulator to desired pressure. Close valve and check for pressure drop. Way quicker than the older pump styles.

love not having to pump up the cooling system

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 SUVâs. 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. Itâs too easy to point out and condemn the water pump when itâs 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 donât believe itâs worth removing a star for that.

Good quality, great design and function

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!

Love it. Air it up and hold pressure to find leaks. Set your cooling system pressure and monitor for leaks. No need to keep pumping.

You don’t need to do the manual pump..cheaper than snap-on tools..
