CXPRO Radiator Pressure Tester & Coolant Vacuum Refill Kit, 28‑Piece — 35 psi Pump, Vacuum Fill

The CXPRO 28-piece Radiator Pressure Tester and Coolant Vacuum Refill Kit is an all-in-one garage toolset for locating cooling system leaks, testing radiator caps, and performing vacuum-assisted coolant fills.

This kit combines a hand pump pressure tester, a vacuum coolant refiller, a thermometer, and a broad array of adapters so you can diagnose pressure faults and refill cooling systems cleanly. Everything packs into a molded case for organized storage and portability. It’s built from aluminum, brass, and reinforced hose materials to resist corrosion and frequent garage use.

How will this kit help me find radiator leaks?

The manual pressure tester lets you pressurize the cooling system up to 35 psi (2.5 bar) to reveal leaks at hoses, gaskets, and radiator cores without running the engine. When pressure drops, you can identify leaking components quickly and accurately, saving time over trial-and-error repairs.

• Pressure range: 0–35 psi (0–2.5 bar) for controlled leak diagnosis.
• Color-coded adapters make matching radiator caps and expansion necks fast.
• Durable gauge face provides clear, shock-resistant readings.

What makes vacuum refill easier and cleaner?

The included vacuum coolant refiller pulls air out of the cooling system so coolant flows in without trapping air pockets. That reduces the risk of post-service hot spots and makes bleeding the system straightforward, especially on modern cars that are sensitive to trapped air.

• Vacuum range: -30 to 0 inHg for effective air removal.
• Brass fittings and reinforced hose minimize leaks during transfer.
• Universal tapered adapter handles odd-sized filler necks.

Which vehicles and components will this kit fit?

The set contains 28 pieces including three common radiator cap test adapters, 17 additional adapters, connectors, and a universal tapered adapter to cover a wide variety of makes and models. It’s designed to work with both expansion tank necks and traditional radiator caps.

• Adapters suit popular brands such as Mercedes-Benz, BMW, Audi, VW, Ford, GM, Toyota, Honda, Nissan, Mazda, and Subaru.
• Color-coded caps simplify selection for different neck styles.
• Adapter handle and connectors included for secure attachment during tests.

How durable and accurate are the tools in this kit?

Key components use premium materials: an aluminum pressure pump cylinder and an anti-shock gauge face for reliable readings, plus brass fittings on the vacuum refiller and hose ends. The thermometer reads 32–400 °F to help you monitor operating temperatures while diagnosing cooling system issues.

• Aluminum pump and shock-proof gauge for long-term accuracy.
• Brass and corrosion-resistant hose parts to withstand coolant contact.
• Clear instructions guide both experienced mechanics and DIYers.

Who is this for? The CXPRO 28pcs Radiator Pressure Tester & Coolant Vacuum Refill Kit suits professional technicians and experienced DIY mechanics who work on a range of cars and need a compact, reliable diagnostic and refill solution. If you regularly service cooling systems, want to reduce guessing when tracking leaks, or need a cleaner method to replace or top up coolant without trapped air, this kit provides the adapters, tools, and durability required for repeat use.
