I'm attending YouTube university to try to train myself to be more than a parts-changer. This sort of video on the basics is a great help. Thanks!

I'm about to test my VW Routan. I had an issue while camping in 2021. My fiancé cobbled a tester with a bike pump and rags- that was a doozy! I just bought a Maddox kit. Appreciate the video, let's see what happens!

On the vast majority of VWs from the last 25 years, I find the easiest way is to apply pressure to the small return pipe to the reservior. That way you don't need all the adaptors and also are testing the cap.

Excellent brother. Please make more videos

Hi Adam. Thanks for the video. 5:20 are all of those colored adapters anozied aluminum or some metal? The ones on Amazon look like plastic and copies of originals. I've read a lot of not so good and conflicting reviews of those products, such as not fitting the radiator or expansion tank, and leaky adapters. Just curious to find the one that's worth dropping some money on, with Vacuum Lift and Pressure Tester.

Does this pressure test works on other leaks such as at hoses, joints, heater core, thermostat?

Hi Adam, I have a coolant leak that I'm trying to troubleshoot on my VW crafter, but I'm struggling to find a pressure tester kit with the suitable adapter for the expansion tank. Any idea where I could find one?

Excellent straight forward video!! 👍🇨🇦

[MennovanLeeuwen-ij]

Hoe cn you diagnose if the leak is in your system of in the tool. Mine stays fine for 5 minutes, but between 10-30 minutes losse 1, 5 psi

[BimmerFix]

Cool to see to you test an E39 V8 :)
How long is the 15 psi pressure supposed to hold?
I'm testing cold my X5 2002 3.0 M54, and the pressure drops from 20psi to 15 psi in 10 minutes, and from 15 psi to 10 psi in another 10 minutes.
Not seeing any leaks.

[migmogg]

Would you recommend the mastercool kit ?

[joelrodriguez]

I tried it on my car but all it does is bubbles in my coolant reservoir. Why is that ?

[OldSchoolNoe]

very nice! should of included a short section on using adapters to test the radiator cap.

Is this a good test to run If I suspect a possible intake leak? I’m getting coolant into my oil.
