EPAuto Spill Proof Radiator Coolant Filling Funnel Kit

I was skeptical that this unit would remove air from my coolant system on my Jeep Wrangler. But being patient (about 20 minutes), I started seeing air bubbles. I had air stuck in the system from changing out a thermostat and it ran fine for about a month. Now it started overheating so I thought it was air stuck in the system. I used this product but putting about 10oz of antifreeze in the funnel and ran the vehicle at idle. Air bubbles escaped once the engine heated up. I used the plunger to keep the antifreeze from spilling out of the funnel and it fit perfect. Good quality for the price and worked great! Vehicle is not overheating!

It took some figuring out to see which attachment fit my radiator, but this thing worked flawlessly. Burped out all the air bubbles it was airtight and rigid. Did not fall even though my car was on ramps.

I've only used it once so far, but it did a great job! I've always had trouble getting the air out of the trucks radiator, not now.

many fitments, works perfectly. if your heater isn't working properly after you change the radiator, you need this!

Great kit! Does what it says.Pros:- Many adapters to accommodate many vehicle types.- Solid build quality.- Overfill plug to return excess coolant to container was flawless perfection.Cons: The adapter for my car was machined perhaps a bit too close to perfect tolerance, could not get it on my radiator fill port without bending the flanges on the adapter slightly. It still worked perfectly, but needing to modify the tool for basic use does pull off a star for me.Otherwise, a great product, definitely recommend, just be ready to make some modifications if fittings happen to be slightly too tight to fit.

This is the first time I’ve ever felt the coolant loop was completely air-free. My mechanic and I were impressed by the results when all the air bubbles were expelled from the loop—no leaks at all when everything was properly equipped. It’s easy to use and fits perfectly on Korean cars like the Kia and Hyundai.My mechanic ordered one immediately because he loved it!

Worked exactly as expected and made my coolant flush go super easy with very little cleanup.

Had to change thermostat on a 2017 Jeep JKU found the right cap size (red) and was able to refill antifreeze without an issue. Was able to monitor for bubbles evacuating from the system. The plug works well as I removed the funnel without spilling antifreeze and put left over in the reservoir tank. Will recommend.
