Orion Motor Tech Coolant Pressure Tester Kit — 19pc Radiator Tool with 35 PSI Gauge & 15 Adapters

Orion Motor Tech's OMT 19pc Coolant Pressure Tester Kit is a complete radiator pressure-testing set with 15 adapters and a 35 psi gauge for diagnosing leaks in vehicle cooling systems.

This compact kit gives hobbyists and professional technicians the adapters and hand pump needed to pressurize and evaluate automotive cooling systems without running the engine. The 2.5-inch pressure gauge with rubber boot, color-coded adapters, and molded carrying case simplify setup, while durable aluminum, brass, rubber, and nylon components are intended for repeated garage or shop use. Use it to isolate exterior radiator and hose leaks or to check for head gasket and internal system issues by holding pressure and monitoring for drops.

How do I use this kit to find a cooling-system leak?

Attach the correct adapter to the radiator or coolant reservoir, pump the hand vacuum/pressure pump to the target pressure, then watch the gauge for pressure loss. If pressure drops, inspect hoses, clamps, radiator seams, water pump, heater core, and visible gasket areas for evidence of leaking coolant or air escape.

• Select one of 15 color-coded adapters that fits your fill neck.
• Use the included wrench and O-rings to secure a tight, leak-free connection.
• Pressurize up to 35 psi and monitor the 2.5 in. gauge for steady readings.
• Use the probe thermometer to compare coolant temperatures if needed.

Which vehicles will these 15 adapters cover?

The adapter set is designed to fit a broad range of passenger cars, light trucks, and many foreign models. While not every single model on the road is included, the kit lists common OEM sizes for brands such as BMW, Ford, VW, Mercedes-Benz, Nissan, Porsche, Fiat, Peugeot, and Chrysler.

• Color-coated adapters for quick identification by size and type.
• Molded size markings on each adapter for fast selection.
• Adapters work with common radiator and expansion tank necks used across many makes.
• Always verify thread and neck type before applying pressure to avoid damage.

What pressure range and gauge accuracy can I expect?

The included 2.5-inch pressure gauge reads up to 35 psi (approximately 2.5 bar), suitable for most automotive cooling-system pressure tests. The rubber-coated gauge face helps protect against impacts in a busy shop while keeping readings visible during testing.

• Gauge maximum: 35 psi (2.5 bar) — adequate for typical passenger vehicle system checks.
• Protective rubber boot shields the gauge and improves grip.
• Manual pump lets you apply and hold pressure without running the engine.
• Brass and aluminum fittings aimed at consistent sealing and repeatable performance.

What comes in the kit and how is it organized?

The OMT 19pc kit includes a manual vacuum/pressure pump, a 2.5 in. gauge, 15 adapters, probe thermometer, wrench, spare O-rings, and a molded carrying case. Everything nests into foam-molded slots so tools remain organized and transportable between jobs.

• 19 pieces total: pump, gauge, 15 adapters, probe thermometer, wrench, O-rings.
• Color-coded adapters and clear size markings reduce selection time.
• Molded carrying case prevents rattling and lost parts in transit.
• Materials: aluminum alloy, brass, nylon, and rubber for durability.

Who is this for? The Orion Motor Tech OMT 19pc Coolant Pressure Tester Kit is made for DIY mechanics, mobile technicians, and small repair shops who need a portable, organized set to diagnose radiator, hose, and cooling-system leaks quickly. It suits garages that service many vehicle brands and owners who prefer to test systems safely without running the engine. If you require factory-specific adapters for an uncommon model, verify compatibility prior to purchase; otherwise this kit covers a wide cross-section of common automotive cooling connections.
