It is vital to make sure that your feed line stays wholly submerged in the coolant because if not, it will suck up air, and then basically, you have to start all over.Then you can close off the feed line, remove the shop air and remove the filler from the filler neck. Just continue to let it fill until there is no more vacuum in the system. Once it gets back up into the green area, you can close off the air and then

Then you can close it and reapply vacuum to the system. You will want to slowly open the fill valve and let the feed line fill up entirely with antifreeze. Once you see that the system is having, you put the end with the filter into the Now close the valve and make sure it holds the pressure.

Watch the gauge up until it goes into the green zone, and then I like to leave it there for a minute or two just to be sure we got all the air out. Slowly open the valve on the same side of the shop air.

Valves are closed and install it in the radiator fill. Once you get the bucket filled up, then you are going to take the tool. You can do this right out of the jugs, but it does make it a lot easier if you use it out of a bucket. We usually like to add 3 to 4 gallons of the mixture into a nice clean 5-gallon bucket. To use this tool, the first thing you are going to need is a clean bucket and fill it up with a 50/50 mixture of any antifreeze the vehicle calls.įor instance, you may use the NAPA UNIVERSAL EXTENDED LIFE and then obviously 50 percent coolant and 50 percent water, or if you buy the premix diluted, you can also use that. And once you are all set, you pull this off, just top it off a little bit, and it is good to go. Using a coolant vacuum filler, you may stop all of that. Is there any other way to fill a cooling system?.
