Orion Motor Tech Coolant Pressure Tester & Vacuum Radiator Filler Kit, 26pc — 18 Adapters, Carry Case

The Orion Motor Tech 26-piece coolant pressure tester and vacuum refill kit is a complete garage solution for finding cooling-system leaks and refilling radiators without air pockets.

Whether you’re a DIY mechanic or a professional technician, this kit combines a vacuum radiator filler, a pressure tester, and 18 color-coded adapters so you can pressure-test, diagnose, and refill most passenger cars and light trucks quickly and cleanly. The set includes a thermally resistant hose, refill wrench, brass fittings, O-rings, and a molded carry case so parts stay organized and protected between uses.

How does this kit locate cooling system leaks?

The pressure tester component lets you apply a controlled pressure to the closed cooling system to reveal leaks at hoses, radiator cores, heater cores, water pumps, and gaskets. Observing a steady pressure drop or visible coolant seepage points you to the failing component so you can make targeted repairs.

• Uses a hand pump to build and hold pressure for inspection
• Includes adapters to seal various radiator and expansion tank necks
• Brass fittings and durable hoses show leaks and withstand repeated testing

How does the vacuum refill feature prevent air pockets when refilling?

The vacuum refill tool evacuates air from the cooling system before you introduce new coolant, enabling a continuous, bubble-free fill. Removing trapped air reduces hot spots and ensures the coolant circulates correctly once the engine runs.

• Vacuum pump draws system to low pressure for smooth coolant flow
• Refill fittings and wrench lock the adapter to the filler neck during filling
• Clear hose and thermometer help you monitor fluid level and temperature

Will the adapters fit my vehicle’s radiator or expansion tank?

This kit includes 18 color-coded adapters with size markings aimed at broad compatibility across many makes and models, including European and domestic brands. The markings and color coding speed up selection so you can establish a proper seal without guesswork.

• 18 adapters cover common sizes for BMW, Ford, VW, Mercedes, GM, Nissan, and more
• Color coding and etched sizes simplify the matching process
• O-rings included to ensure a secure, leak-free connection

What materials and accessories are included for durability and convenience?

Orion Motor Tech built the kit with robust materials — aluminum alloy, brass, nylon, and heat-resistant rubber — to handle shop conditions and repeated use. The molded carrying case protects components and keeps everything organized for transport between jobs.

• Aluminum alloy pump components for lightweight strength
• Brass fittings and durable hoses for reliable seals and longevity
• Thermometer, refill wrench, and spare O-rings included for complete serviceability

Who is this for: This 26-piece Orion Motor Tech kit is ideal for home mechanics who perform their own cooling system maintenance, mobile technicians who need a compact, all-in-one solution, and small shops that want a multi-vehicle pressure test and vacuum fill tool. It’s most useful when diagnosing leaks, replacing hoses or radiators, or performing complete coolant changes where eliminating air pockets matters for engine temperature control.
