A. The kit contains five pieces: one hand-operated pressure pump with an integral gauge, adaptor quick connector, and pressure release push pin, plus four universal cone adaptors covering the size ranges 17–24 mm, 28–31.5 mm, 37–39.5 mm, and 47–48.5 mm. All components are supplied in a blow moulded plastic case.
A. The four universal cone adaptors are designed to replace both screw and bayonet type cap fittings, allowing the kit to be used across a wide range of vehicles without requiring a dedicated cap adaptor.
A. The hand-operated pressure pump is connected to the cooling system via a selected cone adaptor. The pump is then operated by hand to pressurise the system. The integral gauge allows the pressure level to be monitored throughout the test, and the pressure release push pin enables safe depressurisation before the adaptor is removed.
A. The kit includes four cone adaptors: 17–24 mm, 28–31.5 mm, 37–39.5 mm, and 47–48.5 mm. Select the adaptor whose size range corresponds to your vehicle's coolant reservoir or radiator filler neck diameter. If you are unsure of the correct size, please refer to your vehicle's service documentation or contact us before ordering.
A. No. The 53591 uses a capless tester design with the universal cone adaptor system, meaning the adaptors seal directly into the filler neck opening and replace the function of both screw and bayonet type cap fittings during the test.
A. All five components are supplied inside a sturdy blow moulded plastic case, keeping the pump and cone adaptors organised and protected during storage and transport.
