Acymner Radiator Pressure Tester Kit 18‑Piece — Hand Pump Gauge, 13 Color‑Coded Adapters

The Acymner 18PCS Radiator Pressure Tester Kit is a hand‑pump leak‑down toolset that pressure‑tests cooling systems and helps locate radiator, heater core, and cap leaks quickly and reliably.

This all-in-one kit pairs a rugged hand pump and analogue gauge with 13 color‑coded radiator adapters, a stainless steel thermometer and a compact carrying case so you can test coolant system integrity anywhere — from home garages to professional repair bays. The set is built for repeated use: quick‑couplers for fast adapter swaps, a thumb relief valve for controlled depressurization, and durable components designed to resist wear from coolant exposure.

How do I perform a basic radiator pressure test with this kit?

Testing takes only a few minutes and doesn’t require removing large components. Fit the matching adapter to your radiator neck, attach the pump, and introduce pressure to the recommended range. Monitor the gauge and inspect for leaks where pressure drops or bubbles appear.

• Choose the color‑coded adapter that matches your radiator opening.
• Attach adapter with the self‑locking quick coupler for an airtight seal.
• Pump until the gauge reads 10–15 psi (do not exceed 35 psi).
• Observe gauge for 10 minutes; pressure loss indicates a leak.

Which components are included and what are their uses?

The set contains purpose‑built parts to test a wide variety of vehicles and cooling system access points. The thermometer measures coolant temperature while the connectors and handle make adapter swaps quicker and safer. Everything fits in the included carrying case for neat storage and transport.

• 1 hand pump with pressure gauge for controlled pressurization.
• 13 radiator cap adapters (3 chromed steel, 10 anodized) to fit many makes/models.
• Stainless steel thermometer (0–200°C / 32–400°F) to read coolant temperature.
• Connector pieces, adapter handle and a compact hard case for organization.

What safety or durability features should I expect?

The kit emphasizes user control and long service life: the quick‑coupler and thumb relief valve allow safe pressure release, and materials are selected for corrosion resistance and toughness. Follow the pressure limits and basic safety steps to avoid damage or injury.

• Thumb‑operated relief valve prevents sudden depressurization.
• Stainless thermometer resists corrosion for accurate readings over time.
• High‑strength fittings and anodized adapters for extended service life.
• Built‑in gauge calibrated for automotive coolant system ranges.

How does this kit save time compared with trial‑and‑error repairs?

Rather than replacing parts blindly, pressure testing pinpoints whether the radiator, caps, hoses, or heater core are leaking. Detecting a pressure drop during a controlled test quickly narrows the fault location, so you can plan the correct repair and avoid unnecessary parts replacement.

• Diagnose leaks in about 10 minutes instead of prolonged road testing.
• Color‑coded adapters speed up identifying the correct fit for your vehicle.
• Portable case lets you carry the toolset to roadside or shop jobs.

Who is this for? The Acymner 18PCS Radiator Pressure Tester Kit suits DIY mechanics, mobile technicians and small repair shops that need a dependable, portable way to find cooling system leaks without guessing. It’s ideal for anyone who services multiple vehicle makes or wants a reusable toolset for routine coolant system checks.
