Feature Test caps material: Nylon Temperature gauge operates at 32 - 400℉. Quick coupling design for easy connection with test caps and coolant fill hose. End with brass adaptor for long service life. Built-in filter to catch impurities. Double adapters: American adapter, European adapter

Installation and use 1. Choose a suitable adapter and screw the adapter onto the radiator filler neck,and connect the pressure tester to adapter. Adjustment the pump pressure to the range between 10 and 15 psi and check if the gauge reading change. If it does, there could be leaks in the cooling system. NOTICE!!! Do not pump the pressure up to 35 psi.

2. Drain coolant from the radiator. Hook the gauge underneath the car’s hood. Connect shop air to shop air connector and connect the conical adapter or a suitable test cap onto the radiator filler neck. Turn on the air switch and air control valve, while coolant control valve remains off, to create a vacuum in the cooling system. When the pressure falls into the range between -50 and -60 cmHg (-20 and -25 inHg), turn off the air control valve and then air switch

3. Connect the coolant hose to the coolant hose connector. Put the hose into a container filled with pre-mixed new coolant. Turn on the coolant control valve (while the air control valve and air switch remain off), coolant will be introduced into the radiator immediately. The refilling process is completed when the gauge reads zero. (repeat vacuum and refill if necessary)
