Engine cooling system leaks are a common concern for the vehicle owner and technician. This video covers the procedure for conducting a cooling system pressure test using specialty tools. Not only is this a good way to locate a leak within the system, it is a great way to verify the integrity of repairs.

I'm attending KZfaq 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.

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

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

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

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.

I nought a un expensive test kit when i went to use it on 2008 acadia air was coming out of overflow canister not letting get pressure

This seems to be somewhat of a common issue, even with quality adapters. When I was a technician, one of my favorite cooling system pressure tools was a bladder type. This one typically avoided issues like what you're describing.

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.

@AdamsAnalysis 8 ай бұрын

Thanks for watching! All the kits, including Snap-On, have a mix of anodized aluminum and plastic adapters. In most cases, they work just fine. Depending on the scope of vehicles you plan to work on, it may be better to buy the pressure test kit and vacuum lift separately.

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?

Make your own and run it off the expansion hose

Yo Adam, where have you been bro? Now you got to put a scope on the radiator and show the waveform with a pulse sensor.

It's always hard to get time together to make videos throughout the Fall and Spring semester. Scope the cooling system? This would be interesting to compare a good engine vs one with a failing head gasket.

The only car with an actual leak is, of course, a BMW. I can attest as an owner of one. That is the biggest, most persistent problem on them.

@crazienick1010 Жыл бұрын

A lil unreliable in some cases considering the system being pressurized by the tool yet apply physical pressure helped use to confirm the leak. Once you let go the line it stopped spewing so the tool appears to be limited with certain leak. Otherwise well done and very informative

Thanks for watching. It's not always easy to find a live example when filming, so this kind of worked out.. even if I had to flex it. The trail of residue told a better story.

Would a pressure test cause more harm than good?

@AdamsAnalysis Жыл бұрын

When performed at the proper pressure, this test cannot cause any harm. The goal is to replicate the operating pressure specified by the radiator or expansion tank cap. On electric vehicles, it is important to review the operating pressure. Many EV cooling systems operate at low levels such as 3-5 psi.

Wouldn’t you only be testing half the system since the thermostat is cold/closed?

@AdamsAnalysis Жыл бұрын

The thermostat is in place on one side of the system, there is still a path for the pressure to reach all components.

@thelegand1 Жыл бұрын

@@AdamsAnalysis ah ok so flows but just under small pressure until the thermostat is open, i’m losing coolant but when I do the pressure test it’s completely solid so I was thinking possibly because thermostat was closed. Any suggestions?

@AdamsAnalysis Жыл бұрын

@@thelegand1 The thermostat is just a valve to regulate when coolant flows through the radiator for full cooling. When the engine is below the thermostat's opening temperature, it is able to circulate in the engine block and heater core. The pressure in the system is created by the expansion of coolant while it increases in temperature. I would make sure you are testing at the rated pressure of the cap, usually around 15 psi. Have tried this with both a cold and hot engine? Be extra mindful if you conduct the test while things are hot. If you do not see any external leaks, it is possible a head gasket leak is occurring. Also, don't forget to check inside the vehicle to verify the heater core is not leaking. What make, model and engine is the vehicle?

@thelegand1 Жыл бұрын

@@AdamsAnalysis i’ve tested at the operating pressure but only when cold. But wouldn’t head gasket or heater matrix still show up on the gauge when the pressure drops? This is the issue as it doesn’t drop after leaving it on for even 15 minutes
