Acymner Radiator Pressure Tester Kit 18PC – Portable Cooling System Leak Detector with Gauge & Thermometer

The Acymner 18PCS Radiator Pressure Tester Kit is a portable, all-in-one cooling system pressure tester that locates leaks and checks radiator cap performance quickly and accurately.

This kit bundles a hand pump with gauge, a stainless steel thermometer, and 13 color-coded adapters to fit a wide range of vehicle radiator openings. Designed for DIY mechanics and professional techs, it makes it simple to pressurize the cooling system, hold a target pressure, and observe pressure loss or temperature while you inspect hoses, heater cores, and radiator seams.

How do I use the Acymner tester to find a coolant leak?

Using the kit is straightforward: remove the factory radiator cap, select the matching adapter, and attach the quick-coupler. Pump to a safe test pressure, monitor the gauge, and watch for steady pressure loss which indicates a leak location to inspect.

• Choose the correct color-coded adapter that matches your radiator neck.
• Attach the adapter with the self-locking quick coupler for an airtight seal.
• Pump to 10–15 psi and observe gauge for at least 10 minutes.
• If pressure drops, inspect hoses, radiator, heater core, and cap seals.

What parts are included and how do they help speed diagnostics?

The kit comes with a pressure pump and gauge, a 0–200°C stainless-steel thermometer, three chromed steel adapters, ten anodized adapters, two connectors, an adapter handle, and a carrying case. Each component is made to withstand repeated use and makes each step — fitting, pressurizing, measuring — faster and more reliable.

• Pressure pump with thumb relief valve for controlled venting.
• Gauge calibrated for automotive cooling systems to spot small leaks.
• Thermometer to confirm coolant temperatures during testing.
• Carry case stores adapters neatly for quick model matching.

Is the kit durable and safe for repeated garage use?

Acymner engineered the components from robust materials for longevity and repeated testing. The metal adapters and reinforced pump body resist wear, while the thumb-operated relief valve and recommended pressure limits help prevent over-pressurization when used correctly.

• High-strength metal and anodized finishes resist corrosion and wear.
• Self-locking couplers reduce accidental disconnection during tests.
• Manual relief valve lets you safely lower pressure after testing.
• Follow the 10–15 psi working range; avoid exceeding 35 psi.

Who is this for:

This Acymner 18PCS kit is suited for home mechanics, fleet maintenance, and small repair shops that need a dependable, portable solution for cooling-system diagnostics. If you perform routine coolant changes, diagnose overheating events, or want to verify radiator caps and hoses without lifting the engine out, this kit gives clear, repeatable results without specialized equipment.
