Thank you very much sir for such a good explanation. It helped me find 3 small leaks around the engine I had no clue about it...

I’m considering getting a Hazet pressure testing setup, just for working on some of our older, high-mileage cars in the family. Have you heard much about the testing causing problems in older cooling systems, where the vehicle was “getting by” under lower stress grocery store driving, etc.? In other words, will the hand pump burst our 200k mile heater cores if they were getting close to clogging or bursting?

I have not heard of the testing causing a system to fail prematurely but I suppose it would be possible since manufacturers recommended going 1 or 2 psi over what the cap is creating. If you want to be on the safe side, you could pressure test the system to only what the cap tested at. For example, if the cap is rated at 15psi but tested at 12psi, only test the system to 12psi. I can't see how testing to the exact pressure of the cap would cause the system to fail under the stress of testing if it wasn't going to fail anyway with the cap.

Thank you for the video very helpful. But what test kit are you using?

[@JimMackHeavyEquipment]

I am using the Snap-On SVTS272 pressure test kit. It looks like they have a slightly newer version available here: shop.snapon.com/product/Cooling-System-Testers/Cooling-System-Pressure-Tester-Kit/SVTS272A
