Orion Motor Tech Coolant Pressure Tester Kit — 19-Piece Radiator Leak Detector, 35 PSI Gauge & Adapters

Orion Motor Tech's OMT 19-Piece Coolant Pressure Tester Kit is a complete radiator pressure and leak-detection set designed to test automotive cooling systems up to 35 psi quickly and accurately.

Diagnosing leaks and pressure issues in a vehicle's cooling system can save time and prevent overheating-related breakdowns. This 19-piece kit combines a 2.5-inch pressure gauge, a manual vacuum pump, 15 interchangeable adapters, a probe thermometer, and durable fittings in a compact molded case so you can identify internal or external coolant leaks at the radiator neck, filler cap, or coolant hoses without guesswork.

How does this kit find radiator and cooling-system leaks?

The kit pressurizes the cooling system to a controlled level (up to 35 psi), allowing you to watch the gauge for immediate pressure loss and inspect connections, hoses, and the radiator for escaping coolant or air. Using the correct adapter creates a tight seal at the filler neck to isolate the system during the test.

• 2.5 in. pressure gauge with rubber guard for clear readings.
• Manual vacuum/pressure pump to raise system pressure safely.
• 15 color-coded adapters for secure sealing on many filler necks.
• Brass fittings and O-rings minimize false leaks at test points.

Which vehicles will these 15 adapters work on?

The 15-adapter assortment covers a wide range of European, Asian, and domestic passenger cars and light trucks. Color coding and molded size markings help you quickly match the adapter to the radiator or reservoir opening for a reliable seal across many makes and models.

• Fits common brands like BMW, Ford, VW, Mercedes, Nissan, and more.
• Adapters sized for radiator necks, coolant reservoirs, and aftermarket caps.
• Quick identification via molded markings and color codes.
• Extra O-rings included for wear-and-tear replacements.

How accurate and durable is the pressure gauge and pump?

The kit includes a 2.5-inch, easy-to-read pressure gauge rated to 35 psi and protected by a rubber boot to resist impact. The pump and fittings are built from aluminum alloy, brass, nylon, and rubber to withstand repeated use while maintaining consistent readings.

• Gauge scale up to 35 psi (2.5 bar) for typical automotive systems.
• Rubber-coated gauge housing for drop and abrasion protection.
• Aluminum alloy and brass components for corrosion resistance.
• Replaceable O-rings to preserve sealing performance.

What additional tools are included and how do they help?

Beyond the gauge and adapters, the kit supplies a probe thermometer, a wrench for adapter changes, and a molded carrying case to keep tools organized and portable. These extras let you measure coolant temperature, swap fittings quickly, and transport the set without losing parts.

• Probe thermometer for checking coolant temperature during diagnosis.
• Wrench for tightening adapters and replacing fittings safely.
• Molded carrying case with cutouts for each component.
• Color-coated parts make field work faster and more accurate.

Who is this for: The OMT 19-Piece Coolant Pressure Tester Kit suits DIY mechanics, independent shops, and fleet technicians who need a robust, portable solution to diagnose cooling-system leaks reliably. It's especially useful for owners of European and domestic vehicles who want a broad adapter range, clear pressure readings, and a durable kit that keeps tools organized between jobs.
