Every car and truck i have used it on it fits and works perfectly ### ⭐⭐⭐⭐ Finally got to use it! *by C***R on October 12, 2025* Finally used this kit for the 1st time, & it worked well. The only reason I gave it a 4 is because the instructions aren’t exactly for the kit I bought. The picture on the front matches the kit, but the picture inside for the list of fittings per vehicle doesn’t match the kit. And the instructions aren’t exactly very “simple.” Example- says my car is 28-6, but when you look at the diagram/picture, none of the fittings are labeled with the “28” prefix. Just 1,2,3,4,…. And those are for newer cars more than likely have the screw caps like on the surge tanks- not the traditional radiator caps. There are only 3 sizes of the traditional caps. Fortunately, it’s not rocket science. If you have a traditional radiator caps like mine, just match it up with 1 of the 3 in the kit. The pump hose is easy to attach & remove . But one word of advice- if remove the hose connector from the tester cap & it has pressure on it, be sure to press the relief valve/button before removing! Yes, fluid will come out with the air, but if you don’t relieve it fully before removing, expect to get sprayed!!!! lol I forgot & I fluid sprayed shot up out of the connector all over the engine. But Ll in all, it’s a pretty good kit, especially for the price. And the case is pretty organized & fairly sturdy. Decent snap clamp/clips. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/673275889-koopool-30pcs-radiator-pressure-tester-kit-with-vacuum-refill-coolant](https://www.desertcart.us/products/673275889-koopool-30pcs-radiator-pressure-tester-kit-with-vacuum-refill-coolant) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-07-26*
