Punmew Radiator Coolant Pressure Tester Kit — 18pc Leak Detection Kit with Gauge & Thermometer

Punmew Radiator Coolant Pressure Tester Kit is an 18-piece diagnostic set that pressurizes and tests automotive cooling systems to find leaks, help replace coolant, and remove trapped air.

If your car is losing coolant, overheating intermittently, or you suspect a slow leak, a pressure tester lets you verify system integrity before replacing parts. The Punmew kit brings a complete range of adapters, a double-scale thermometer, and a robust gauge in a compact case so both professionals and DIYers can run quick, reliable checks on radiators, expansion tanks, heater cores, hoses, and caps.

How does the Punmew kit detect radiator and coolant system leaks?

The gauge and sealing adapters let you pressurize the system to the vehicle’s specified pressure, revealing drops that indicate leaks. Because it works from the radiator neck or expansion tank, it exposes external leaks and weak seals without the engine running.

• Use the included chromed steel and anodized adapters to fit many radiator caps and reservoirs.
• Pressurize with the adapter handle and watch the gauge for pressure loss over time.
• Identify slow leaks in hose clamps, seams, or the radiator core before they worsen.

Can I use this kit to replace coolant and remove air from the system?

Yes — the kit supports controlled pressurization and bleeding, which makes coolant exchange and air removal simpler and cleaner. Pressurizing the closed system forces trapped air into the bleed points so coolant fills passages fully, reducing hot spots and helping consistent circulation.

• Open bleed valves on your vehicle while the system is pressurized to evacuate air pockets.
• Top up coolant under pressure to prevent new air from entering.
• Double-scale thermometer helps you monitor fluid temperature during service.

What components are included and how do they fit different vehicles?

The Punmew 18-piece kit contains a pressure gauge assembly, a double-scale thermometer, multiple adapters and connectors, a handle, and a storage case. The mix of chromed steel and anodized adapters along with plastic connectors covers a wide range of radiator necks and expansion tank designs found on most cars and light trucks.

• 1 x coolant pressure tester with gauge, 1 x double-scale thermometer for temperature reference.
• 3 x chromed steel cap adapters and 10 x anodized cap adapters for broad compatibility.
• 2 x plastic connectors, 1 x adapter handle, and a sturdy storage case for organized transport.

Is the kit durable and easy to store or carry?

Punmew builds the kit from materials chosen for sealing strength, toughness, and corrosion resistance, so it stands up to repeated garage use. The included hard storage case keeps each adapter secure, protects the gauge, and makes it easy to carry the set between jobs or keep it in your vehicle.

• Chromed steel and anodized fittings resist wear and maintain reliable seals.
• Compact case with molded slots prevents lost parts and damage to the gauge.
• Lightweight adapters and a single handle make one-person operation straightforward.

Who is this for: The Punmew Radiator Coolant Pressure Tester Kit suits automotive technicians, home mechanics, and owners who want to diagnose cooling-system faults accurately. If you perform routine coolant service, troubleshoot intermittent overheating, or prefer to verify radiator and hose integrity yourself, this all-in-one 18-piece set provides the adapters and gauge you need in a portable, organized package.
