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

Punmew Radiator Coolant Pressure Tester Kit is an 18-piece toolkit that pressures your cooling system to find leaks, assist coolant exchange, and evacuate air for reliable troubleshooting.

When a radiator or cooling circuit shows low coolant, overheating, or mysterious puddles, isolating the leak source quickly saves time and prevents further damage. The Punmew 18-piece kit bundles a hand pump pressure tester, double-scale thermometer, a wide selection of metal and anodized adapters, connectors, and a storage case so both professionals and DIYers can test expansion tanks, radiator necks, and other service points with one portable set.

How does this kit locate leaks in a vehicle cooling system?

The kit pressurizes the cooling circuit to slightly above normal operating pressure, forcing any escaping fluid or air to become visible at the leak point. You can confirm gasket failures, cracked hoses, or radiator core leaks without running the engine.

• Hand-operated pump creates steady test pressure.
• Wide adapter range fits common radiator and expansion tank necks.
• Visible pressure gauge lets you watch for gradual drops indicating leaks.
• Thermometer helps check coolant temperature during inspection.

What parts come in the 18-piece Punmew set and why they matter?

This kit includes the core pressure tester assembly plus adapters and accessories to cover most vehicle makes and models. Each component is chosen so you can seal and test different filler necks, plastic tanks, and radiator openings without improvising seals.

• 1 x coolant pressure tester with gauge for monitoring test pressure.
• 1 x double-scale thermometer for Celsius and Fahrenheit readings.
• 3 chromed steel adapters and 10 anodized adapters for varied neck sizes.
• 2 plastic connectors, 1 adapter handle, and a fitted storage case for transport and protection.

How durable and user-friendly is the Punmew tester?

Punmew builds the kit from materials chosen for sealing performance, strength, and toughness so the set stands up to repeated garage use. The components assemble quickly and the hard storage case keeps pieces organized and protected between uses.

• Chromed steel and anodized aluminum adapters resist corrosion and wear.
• Robust seals maintain test pressure for accurate leak detection.
• Compact case makes the kit portable and easy to store in a toolbox or trunk.
• Simple pump-and-read operation reduces setup time for routine checks.

Can this tool be used for coolant replacement or bleeding air from the system?

Yes — beyond leak finding, the pressure tester helps with controlled coolant fill and bubble removal when refilling or bleeding cooling circuits. Applying proper pressure while filling encourages trapped air to escape through bleed ports or the overflow tank.

• Use the pump to maintain slight pressure during refill to minimize trapped air.
• Thermometer assists in monitoring fluid temperature during service.
• Adapters allow you to work with factory filler necks and aftermarket expansion tanks.

Who is this for: The Punmew Radiator Coolant Pressure Tester Kit suits professional mechanics, fleet maintainers, and home mechanics who want a single portable set to diagnose radiator and cooling-system issues, perform controlled coolant changes, and speed up air-bleeding procedures. It’s especially helpful for shops that service multiple vehicle makes or hobbyists who prefer to troubleshoot cooling problems accurately before investing in replacement parts.
