I used a very similar tool made by Sealey, as I'd just bought an air compressor anyway. To be sure that it had worked, I bled the system afterwards using the 'see-saw' method. The vacuum filler did not work 100% -- I got a group of little bubbles out with the see-saw method after using the Sealey cooling system filler. My guess is that the complexity and design of the bongo cooling system is not ideal for these vacuum coolant bleeding tools. Although having said that, the small amount of air that remained trapped would probably have been okay.

Your best bet is to save your money and bleed the system using one of the methods described on Bongo Fury.

we have a tool called vacula,the x-rover mechanics told me that the used it for the TF model and has some similarity's to the bongo they both have cooling systems with front to rear pipes and mid mounted engine with rad @the front.Was going to use said tool but these things collapse all the rubber hoses as it draws the air oot and could damage old and worn pipe work? so as a result I would stick to the traditional method as described on the club factsheets .



cheers stevie.

It is quite unnerving seeing the rubber hoses go flat when using the filling tool. Any damage to the hoses or small leaks will be revealed when you suck a vacuum on the system because the vacuum gauge won't hold steady, and you will be able to hear where the leak is. In my case, on the first try I had a leak where the tool attaches to the compressor hose. Had to sort it out before continuing, and it would have been quicker to bleed the system the normal way.
