Must use a high powered air compressor.
This is a great tool. Easy to use and works as advertised. Works just as well as a drain tool. I used it through my oil dipstick tube to remove an overfilled oil tank. Solid quality. Read more

Worked wonderful! Used it on our 2004 F150 4.6. There was no leakage just as advertised. The assortment of adapters have letters on them but don't match the instructions. I looked at the adapter that stated it was for a Ford. No other type of vehicle is mentioned so you have to use an adapter that fits your vehicle. Read more
Great product. Works perfect on my 2015 TOYOTA TUNDRA Read more
Excellent auto tool for a simple coolant changeout & reload. Reasonable $20 price. Prevents trapped air bubbles, if done properly. Variable expansion tank attachments for a variety of cars. Take care to package & store your tool - don’t allow plastic to freeze. Store in a cool basement storage. This is my backup tool for coolant C/O vs the vacuum method, if it does not work as planned.

This is an absolute must for doing anything with coolant. For years I've struggled with trying to bleed air out of different cooling systems and this absolutely solved it. I can fill it up let the car run for a few minutes and watch all the air pockets come out. It's absolutely beautiful. There is no leakage when you get the right cap and it is so nice to be able to close off the valve and only have a tiny amount of coolant come out when you disconnect the thing. It's very sturdy and can definitely withhold an engine running even if it's a big cammed Chevy big block. It's a perfect size and everything fits back into the Container itself so it's a perfect fit for my mobile mechanic business Read more

Fit my 2013 Crosstrek secure with no leaks. felt a little tight at first but twisted right on when it was in the right position. I'm happy with the build quality too. Read more
Have you ever bought a tool and wonder why you didnt buy it 20 years ago? This is how i feel with this tool. It makes filling and burping the radiator much easier and cleaner. It is a great product Read more
