Orion Motor Tech Coolant Pressure Tester Kit — 34-Piece Master Kit with Vacuum Refill & 23 Adapters

Orion Motor Tech's 34-piece Master Coolant Pressure Tester Kit combines leak detection and vacuum-assisted coolant refill into one organized, garage-ready system. This kit gives DIYers and professional technicians the tools to diagnose cooling-system leaks and perform clean, air-free coolant fills without running back to the parts store. The set pairs a hand vacuum pump and purge/refill tool with 22 vehicle-specific radiator adapters plus a universal adapter, so you can pressure-test caps and fill expansion tanks on a wide range of cars and light trucks. Hardened case storage and color-coded parts keep work fast and reduce lost pieces.

How does this kit find cooling system leaks?

The pressure tester portion lets you apply a controlled pressure to the radiator or expansion tank to reveal failing caps, cracked tanks, leaking hoses, or compromised gaskets. With clear fittings and a reliable pump you can observe pressure hold or drop and isolate the leak location.

• Pressure pump with gauge for controlled testing
• 22 dedicated radiator adapters plus a universal adapter for tight seals
• Brass and rubber seals that resist coolant exposure
• Hose clamp pliers and clamps to isolate sections while testing

What makes the vacuum refill and purge system effective?

The vacuum refill tool evacuates air from the cooling circuit before introducing antifreeze, which prevents pockets of trapped air that can cause hot spots and poor heater performance. A vacuum-assisted refill yields faster, cleaner refills and reduces repeated bleeding cycles.

• Hand vacuum pump produces reliable vacuum for bleeding
• Purge & refill tool designed for one-person operation
• Clear hoses let you see fluid flow and air being removed
• Probe thermometer helps confirm coolant temperature during refill

Will this kit fit my vehicle?

The kit includes 23 adapters that cover many domestic and import vehicles, so you can usually match the correct radiator neck or expansion tank opening without aftermarket fittings. Color-coding and size markings speed selection and ensure a tight seal for accurate testing and refilling.

• Adapters compatible with Mercedes-Benz, GM, Jeep, Subaru, Toyota, Honda and more
• Universal adapter for non-standard necks or custom applications
• O-rings and spare fittings provided for reliable sealing
• Molded case keeps adapters organized by color and size

How durable and workshop-ready are the components?

Orion Motor Tech built the set from aluminum alloy, nylon, brass and durable rubber to withstand repeated garage use. The molded carrying case protects small parts and makes it easy to transport between jobs without misplacing adapters or seals.

• Aluminum alloy and brass fittings for long-term use
• Nylon and rubber components resist coolant degradation
• Clear size markings and color coding prevent mixing
• Compact molded case organizes all 34 pieces securely

Who is this for? If you routinely service cooling systems—whether you’re a home mechanic tackling scheduled maintenance or a professional doing radiator and head-gasket troubleshooting—this all-in-one kit speeds diagnosis and gives you the tools to refill coolant cleanly. It’s especially useful for technicians who work on a variety of makes and models and need an organized, reusable solution for leak testing and vacuum-assisted refilling.
