I see people suggesting the AirLift 550000 tool for pulling vacuum on coolant system and refilling. I don't plan to use this tool very often and I see other kits for about 1/2 the price. Does anyone know how to make sure the kit will work on a 2008 ls3? I see they have adapters but not sure if they are universal.

 

Kind of over thinking it.

A small Venturi Vacuum Pumps can be had on the cheap, and all you need to do is adapt a rubber cone section to the vacumm port that be used to push it down against the top of the tank openning to seal against it.



Hence fill up the fluid tank half way, connect your air line to the Venturi Vacuum Pumps so it starts to draw a vacuum, stick the vacuum rubber cone on top of the opened filler tank opening to create a seal to pull a vacuum on the system a few time to pull the air out of the system and transfer the fluid in the tank to fill the air pockets isntead.

Hence the resivor tank is the high side of the system, so you are just putting a vacuum on the tank with fluid in it to draw the air bubbles up to the tank, and let the fluid in the tank transfer back down to fill the air pockets instead.

Just for starters, and if you check around, should be able to find a cheaper small Venturi Vacuum Pump instead to use with compressed air as the power source for the vacuum.

Also, with this set up, makes draining other items a snap as well.

Hence take a one gallon jug, drill a small hole in the top side of it to install a hole, and you now have a transfer tank to pretty much suck anything up into the jug via the hose by just putting the small small Venturi Vacuum Pumps with come to the cap opening of the jug to create a vacuum in it.
