14-piece radiator pressure tester kit with 12 adapters and storage case — accurate, durable leak detection for multiple vehicle models. Key benefits Find cooling-system leaks fast: The 14-piece pressure tester lets you pressurize the cooling system and pinpoint leaks quickly, reducing diagnosis time and unnecessary disassembly. Works with many vehicles: Includes 12 adapters to fit a wide range of radiator necks, caps and filler openings so you can test multiple models without buying extra parts. Built to last and hold vacuum: Hardened aluminum-alloy, rubber and nylon components provide reliable sealing, steady vacuum performance and long service life under workshop conditions. Organized and portable: Sturdy storage case keeps adapters and tools secure and accessible for on‑the‑go use or tidy garage storage. What it does Performs pressure tests on radiators, heater cores and coolant caps to locate leaks and verify system integrity. Restores accurate pressure and vacuum during testing to reveal slow or intermittent leaks that visual inspection can miss. Materials and performance Construction: Aluminum alloy parts for strength, rubber seals for tight connections, nylon for lightweight durability. Performance: Designed to maintain stable pressure/vacuum during testing for repeatable, reliable results. Typical use scenarios Home mechanic diagnosing unexplained coolant loss or intermittent overheating by pressurizing the cooling system and locating the leak without removing the radiator. Service shop performing quick checks of radiator caps and heater cores during routine maintenance or pre-sale inspections. Fleet maintenance crew verifying cooling-system repairs and ensuring seals and hoses hold pressure before returning vehicles to service.
