Orion Motor Tech coolant pressure tester kit — 33-piece vacuum refill & leak test set with gauge

Orion Motor Tech's OMT Master Coolant Pressure Tester Kit is an all-in-one 33-piece system for pressure-testing cooling systems and vacuum-refilling radiators without air pockets.

This complete kit combines a vehicle-compatible pressure tester, a vacuum purge and refill tool, plus 23 radiator adapters and accessories in a molded case so technicians and DIY mechanics can find leaks, verify cooling system integrity, and refill coolant quickly and cleanly. Instead of juggling loose adapters or multiple products, this set centralizes the parts and fittings needed for testing header tanks, radiators, heater cores, water pumps, and hoses across many car makes and models.

How does the kit detect coolant system leaks?

The included pressure tester pressurizes the cooling circuit to reveal leaks at weak points like hoses, the radiator core, or the head gasket. A controlled pressure hold makes slow leaks visible and helps isolate the source before costly repairs.

• Pressure pump and gauge to raise and monitor system pressure safely.
• 22 color-coded adapters plus a universal adapter for tight fits.
• O-rings and brass fittings for secure, leak-free connections.
• Clear hoses to observe coolant movement and seeping locations.

What makes vacuum refilling better than pouring coolant?

Vacuum refilling removes trapped air and draws coolant into the radiator and cooling passages under negative pressure, reducing air pockets that can cause hot spots or poor circulation. This kit’s vacuum pump and refill tool speed refill jobs and ensure the system is filled efficiently and evenly.

• Vacuum pump evacuates air from the radiator and cooling passages.
• Purge & refill tool pulls coolant in without splashing or overfilling.
• Probe thermometer helps confirm operating temperatures while bleeding.
• EU and US air intake joints support different vehicle inlet standards.

Which vehicles and components are compatible with the 33-piece set?

The kit’s 23 adapters cover many European, American, and Asian makes, helping technicians work across a broad vehicle fleet. It’s suitable for testing and refilling header tanks, expansion reservoirs, radiators, heater matrices, water pump outlets, and associated piping.

• Adapters listed for BMW, Ford, Opel, Fiat, VW, Porsche, Mercedes-Benz, Nissan, Peugeot, Chrysler and more.
• Color-coded and molded size markings speed adapter selection.
• Universal adapter accommodates non-standard filler necks.
• Compact case organizes tools for shop or mobile service.

What materials and features ensure durability and ease of use?

Components are made from aluminium alloy, brass, nylon and durable rubber so the tools withstand routine shop use without deforming or corroding. The molded carrying case and marked adapters keep parts protected, visible and ready for the next job.

• Aluminium alloy and brass reduce wear and maintain sealing integrity.
• Nylon and rubber elements resist coolant and temperature exposure.
• Custom molded foam case keeps adapters organized and portable.
• Wrench, probe thermometer and spare O-rings included for complete service.

Who is this for: The OMT Master 33-piece coolant pressure tester and vacuum refill kit is ideal for independent mechanics, mobile technicians, and serious DIYers who service multiple vehicle makes or need a single, reliable solution for leak diagnosis and air-free coolant fills. It’s designed for those who want professional-style testing and refilling without buying separate specialty tools, and for shops that require a portable, organized kit that speeds diagnostics and reduces rework from trapped air.
