Hoping you can give me some advice here. Have the same exact tool. Have my air at 120 lbs. so when I start as you did by submerging tube on coolant with valve open it fills the tube with coolant. Shut the valve off and coolant just simply drains back down the tube. I don’t get it. And I cannot create even the slightest bit of vacuum.
You know anything about the usage of Subaru Coolant Conditioner in 08 and up Wrx 's ? I hear it's just a stop leak product used for the older engines. However, I still see it listed in the service manuals (2013 and 2019 wrx) as strongly recommended with coolant changes. I talked with local Subaru parts department. As far as they know, the conditioner is for Subaru's that use the older green coolant and the Super Coolant already has the conditioner mixed in. I'm confused...
Ideally heater should be "on" or "open" when vacuuming. Not sure about the thermostat, but with 90% of vehicles I have not had issues. BUT some vehicles I have confirmed this does not work on are: Some midships including AW11 and SW20 MR2 and Honda S2000
@@CMAutohaus again great info. I have seen a few videos lately and I think you are the only one to fill the clear tube with coolant first to prevent the added air. Thank you
@@CMAutohaus when it purges the air from the system, any idea if it pulls it from the heater core as well? Meaning its filling the engine block and the other misc components right? I just dont see how it gets past the thermostat or pump.
quick question.. the shop air is pushing air through and out the other side creating a vacuum inside the system while pushing air through it? Venturi effect? I'm confused here lol
i failed miserably using this method.... what kind of air compressor do you need for this? i was using 1 gallon and 6 gallon air compressor with +175 psi and both did not have enough create enough pressure for a vaccumm. i resulted doing the old school burping system with the system on....
You need a bigger compressor. The shop compressor is the 30gal Harbor Freight one. Its air volume, not pressure you need. IIRC my regular is always set at approx 100psi
Although some cars MAY* present an issue. I had no problems on a 3rd gen MR2, but it did not work for me on a 1st gen MR2. Possible user error on my end?
@@CMAutohaus So I'm trying to do this with a Mack dump truck diesel engine cooling system.. I've seen people use this on their trucks.. you think that's enough pressure?
