I believe this test is negative but I would recommend placing the heater on full blast and letting the car warm up all the way so that the thermostat is opening and closing and system is working all the way.
Doesn’t matter if it’s pressurized side or not. If the cooling system is working properly, any gas that enters it will eventually find its way back to the overflow tank. That’s one of the purposes of the overflow tank.
@@jacksonreid6412this is a response I was looking for… i have a 2020 ram 1500. Drove to work, did the test while it was hot and idling. For obvious reasons, took the test in the reservoir tank which at this point the radiator is overflowing into due to the pressure and coolant expansion. Imo, this too, should equal to a valid test due to the radiator “bleeding” into it after pressure build up.

He did the test correctly. The results are showing negative.
Hey buddy… that’s not the pressurized side of the system, try the radiator cap after it’s cooled off 😂
Volkswagens don't have radiator caps just expansions tank/coolant reservoir
Arent you supposed to put your finger over the metal on too of the bulb?
@@Mik35959nah I think that’s where the bubbles are created from needs air other wise it’ll be a closed vacuum. Did you figure it out?
