Did you find a working psi for the flush? I just did my car and used a lot less than you suggested with the ~90psi. I had to do it twice to get it right, using 30 psi, which pulled a -25 psi vacuum. I really like the tool and now that I know how to properly use t I can fine tune the working pressures to get it perfect in one shot. Very well built and in my opinion worth the cost. I’m starting an M car (BMW) specific shop for likeminded enthusiast who love their cars and want to have them properly cared for, outside of the stealership, even if they themselves can not turn the wrench. Great video, I’m now Subscribed and looking forward to going through your catalog of content and future videos. Greetings from VA!
Great feedback, I've had the best luck in the same range you described of about 30psi to match the vacuum pulled by the unit. I tried it once with a pancake compressor for fun, but it did not have the CFM to pull a vacuum.
Do you also see the heater lines compress like the main radiator hose? I assume it also pulls the air from the engine via the thermostat. Do you prefer to use the tool on the overflow tank vs the radiator?
Can you explain how to do a complete flush of the system! I have heard that just opening the bottom radiator hose only gets part of it! How do you do it? Thanks, Tom
You can add in fittings to heater hoses to flush with a garden hose. Many suggest it is only worth doing using hot water to flush the system and doing so in the opposite direction of normal flow. This is to flush out sediment and minerals. Some vehicles need a separate flush for oil or transmission coolers. Some suggest removing the thermostat and having the heater in the high position to open the heater core valve.
Just bought this and system won't hold a vacuum yet there's not a drop of coolant leak and no hissing noise. I've carefully inspected every hose and they're all dry as can be and no coolant around head gasket. The only weird thing is I do hear a gurgling noise every few minutes. I assume that's air pockets being sucked out. I can only figure the universal fitting to the radiator cap isn't sealed perfectly. Disappointed but open to suggestions.
If you have this in the radiator and the tube going to the overflow tank needs to be pinched off. Sounds like it’s pulling vacuum through the small hose.
How much vacuum is too much? I'd like to use as little as possible on my Ls7. Never used one of these before but just picked one up. Also I don't see how this can pull a vacuum on the entire system if the system is already full of coolant. I guess I'll have to drain it?
GARBAGE! The body doesn't fix to the radiator.. they send you some "spacers" to complete the mating to the radiator.. IT NEEDS TO HAVE A RIGID ADAPTER. That one piece makes this problematic to use.. it doesn't create a reliable air tight connection.

What type of compressor did you use?

I'm thinking about purchasing this does anybody know if this will put a vacuum in the whole system or only to the thermostat

I use it unregulated at 150 psi with no issues.

Yes, drain first! This tool is ONLY for refilling (using a vacuum to pull it back into car).
Did you do your video and post it yet as I don't see the reference link above as mentioned in this video. Thanks!
Will this work for a 2013 vw passat.
I don't know why not.
and if there is coolant already in the system you will usually not be able to draw a vacuum or as much as an empty system. lower fluid the better
Have you used this yet? I bought one and am just waiting for it to be delivered.
When I used with with my low cfm pancake compressor it did not work well, but works great with about 5+CFM
I'm not getting a vacuum. Air compressor has 125 PSI
How many CFM is your compressor rated for? It does not play nice with low volume pancake compressors, it probably needs at least 5+ cfm
Look for pressure relief hole in place of connection on car, and if there is, than you should use the cone shaped adapter.
Just got one
