This worked great for changing the antifreeze in our minivan. It made refilling and burping the air out of the system a no mess operation. The adapter fit my radiator perfectly. The volume markings make it easy to add the correct amount of coolant if you need to add a certain amount of concentrated coolant to decrease the freezing point of the coolant. The product is well made, and I plan to use it for years to come.

I was skeptical at first to use, because I've never fooled around with a funnel like this. To my surprise it works really well, easy to use.. color coded cap guard to fit the funnel on the radiator. No mess at all.. just follow 3 easy steps it provides. Well worth having for changing out other fluids, etc.

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.

There are several similar-looking products available. I took a chance on this one and was very pleased with the results. Fits my Jeep JK without leaks. It's a simple design that is easy to set up and use. Just choose the 'cap' that fits your radiator, find the color-matched tube with the o-ring and put the funnel on top. The t-shaped plug makes it easy to transfer unused coolant back into its bottle. All the parts fit back in the funnel and it comes with a plastic lid to keep it all together.

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.

Absolutely a must have piece of equipment. Solid quality and does what it is supposed to. Makes servicing coolant a breeze without the typical mess. Would certainly buy again.

Purchased this to aid in a radiator / overflow drain and refill, worked great. Everything went very smoothly, for my 2019 Toyota Tacoma the blue cap and adaptor were perfect. I am not a mechanic, but this allowed me to complete the job without a hitch, in fact I wouldn't try to do this without this tool. Kept things clean and tidy with very little coolant spillage. Not sure I wouldn't prefer the style where you have a valve you twist vs. the plunger for a stopper, but this saved me a few bucks and worked great.
