KJE 31PCS Coolant Pressure Tester Kit with 23 Adapters & Vacuum Refill Tool

The KJE 31PCS Coolant Pressure Tester Kit is a thoughtfully designed collection built to streamline cooling system service. This comprehensive set combines a robust pressure tester, a vacuum refill tool, and a full range of adapters in a portable case, so you can diagnose and service with confidence.

What sets this kit apart is its breadth: 23 radiator adapters plus a universal adapter ensure broad compatibility across many vehicles. You’ll also find a solid pressure-testing pump with a clear gauge, a vacuum purge & refill tool, a probe thermometer, and a sturdy wrench—all designed to work in harmony to reveal issues and support efficient refilling.

In real-world use, the kit helps locate leaks in radiators, hose connections, pumps, and head gaskets. The vacuum refill function pulls coolant into the system under vacuum, helping to minimize air pockets and improve flow. A large, easy-to-read dial gauge and durable hoses provide clear visibility and reliable connections during testing.

With 23 adapters in a color-coded system, the kit suits many popular brands, including Mercedes-Benz, Toyota, Honda, BMW, VW, Audi, Porsche, Nissan, GM, Ford, and more. It’s a versatile tool for DIY enthusiasts and professional shops alike.

Durable, organized design

Built with brass, aluminum, rubber, and nylon components, the set stands up to high-pressure testing. Reinforced hoses and corrosion-resistant parts offer long-term reliability, while the compact storage case keeps everything neatly organized for on-call jobs.
