I used this when I needed to replace my water pump on my GTI mk7. It made it so much easier to ensure all bubbles were out of the system by removing all air prior to filling up with coolant.
The quickest way to fill the voids in your car's cooling/heating system - period. Very high quality parts, fit 2013 Ford F150 V-8 perfect . Love it !
The tool looks and feels good. I've used it on a jeep cherokee, a nissan pathfinder and with this method you don't have to worry about air in your system. I would recommend buying one if you work on cars often.
This thing works awesome! Saved me hours of troubleshooting and after I replaced my radiator, hoses, and heater core it saved me hours "burping" my cooling system to get rid of all the air. Pros: time, quality, money, and convenience. Cons: none.
