Just replaced a water pump, radiator, or hose? This 27-piece kit gives you three tools for the job: a hand pump to pressure-test the system, connectors to test the radiator cap separately, and a vacuum tool to refill the system after service.\u003c\/p\u003e\n\u003ch3\u003e1. Pressure-test the cooling system\u003c\/h3\u003e\n\u003cp\u003eFit the matching adapter to the radiator or pressurized expansion tank. Use the hand pump and gauge to bring the system to the vehicle manufacturer’s specified test pressure. Watch the gauge and inspect accessible hoses, fittings, and seams for seepage. If pressure falls without an obvious external leak, check the adapter seal and continue diagnosis using the vehicle’s service procedure.\u003c\/p\u003e\n\u003ch3\u003e2. Test the radiator cap on its own\u003c\/h3\u003e\n\u003cp\u003eUse the matching cap-test connector to attach a compatible cap to the hand pump. Testing the cap separately helps you check whether it holds its specified pressure before moving on to the rest of the system.\u003c\/p\u003e\n\u003ch3\u003e3. Vacuum-purge and refill after service\u003c\/h3\u003e\n\u003cp\u003eConnect the separate refill tool to a compressed-air supply to draw air from the drained cooling system. The vacuum then draws fresh coolant through the refill hose, helping reduce trapped air. After filling, verify the coolant level and follow the vehicle’s final bleed and level-check procedure.\u003c\/p\u003e\n\u003ch3\u003eWhat’s in the blow-molded case\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eHand pressure pump with a \u003cstrong\u003e0–35 PSI gauge\u003c\/strong\u003e, hose, and quick coupler\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e19 numbered adapters:\u003c\/strong\u003e steel #2–#4 and aluminum #6–#17, #19, and #21–#23\u003c\/li\u003e\n\u003cli\u003eTwo radiator cap test connectors: blue \u003cstrong\u003eR123\/R125\u003c\/strong\u003e and black \u003cstrong\u003eR123\/R124\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eVacuum purge and refill tool, coolant hoses, and universal rubber radiator adapter\u003c\/li\u003e\n\u003cli\u003eNeedle thermometer and molded storage case\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFit and setup FAQ\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eWill it fit my vehicle?\u003c\/strong\u003e\u003cbr\u003eMatch the adapter to your vehicle’s radiator or pressurized expansion-tank opening.
