Works great! The adapter fit perfectly on my radiator. Nice and snug, no leaks. Color coded parts were obvious to figure out. I didn't have to use any extensions, but I expect they fit just as well. There was surprisingly little splash when removing a full funnel with the stopper from the rad cap adapter after the job. Really critical tool to have for coolant flushes and radiator swaps.

Id never used a tool like this or replaced my coolant before. This kit made it really easy to keep the process clean and to “burp” the radiator without a mess. Easy cleanup and storage. I used this kit on both my 2014 Toyota Tacoma and 2018 Toyota Highlander. Easy to use and do.
