This is a great funnel kit for a garage mechanic. It has the flexibility to fit multiple size radiator openings. It’s a good design that makes it easy to fill the cooling system. Very durable, sturdy plastic funnel with a cover, which I use for storing the additional sizes of adapters. This funnel makes “burping” and removing air pockets when performing a complete flush and fill. Read more

The media could not be loaded. Worked really well. Had to replace to radiator on my car and when I was pouring coolant in, the car was overheating. Using this tool allowed me to get all the air out and car is running like a dream now. Comes with multiple adapters and connectors to fit cars. Extremely easy to use. Very little spillage. Easy to store. Read more

Fit well, good seal, and really made filling much easier. The only spillage I had was slight after after removing the cone portion because it filled to the top. The stopper worked great though--no spill or leak from it and it was easy to transfer the excess back to the container. Read more

Makes bleeding and filling coolant way easier with almost no mess. The funnel sits securely and you can actually see air bubbles working out of the system. Just note that not every adapter fits perfectly on every vehicle, so you may need to test a couple pieces to get a tight seal. Read more

Worked great for filling coolant after radiator replacement on my Subaru Forester. Did not leak and is made to last. All adapters store in funnel and lid ensures nothing is lost. Great design and will last for years of use. Read more

This funnel kit is a game-changer. The EPAuto Spill Proof Funnel eliminates the mess and guesswork from coolant fills and burping procedures. The variety of adapters fit multiple vehicles—including my 2014 Ram 1500 HEMI—with no drips, no splashes, and no wasted coolant. One note: I had to use a green adapter with a red cap. The kit is supposed to be color-coded (red with red), but that combination didn’t work for me. Fortunately, the green adapter sealed perfectly and worked just fine. The transparent funnel lets you monitor flow and air bubbles with precision, and the shut-off valve is intuitive and leak-free. It makes coolant flushes clean and controlled. I also appreciated the fluid ounce markings on the side—they helped me calculate exactly how much coolant to add to reach -34°F protection. I did a complete flush with distilled water, so knowing the precise coolant volume was essential. If you want to make cooling system work easier, cleaner, and more predictable, this kit belongs in your toolbox. Read more

Saw some people saying it wouldn't work with a Nissan Frontier, however, the green cap and plug worked perfectly on my 2022. Filled her up with Asian blue (https://amzn.to/4rdgbcM) and now I have hot heat again. Pop the neck into the radiator rubber seal side down, screw on the green cap, put the funnel in, add coolant, jack the front up, turn the heat all the way up and let it idle until it reaches operating temp. Blip the throttle a couple times. Keep filling the tunnel until it's not bubbling or drinking anymore down. Put the stopper in the funnel, remove, and toss the dirty coolant that comes up. I put mine in an empty soda bottle. I was very surprised how low my coolant truly was. This funnel worked great, could not recommend it more. Read more
