Built from rust-resistant aluminum, reinforced rubber, and impact-resistant plastics, the set includes a calibrated pump and gauges designed to operate in the usual 0–35 psi range used by most passenger cars and light trucks.\u003c\/p\u003e\n\n\u003ch3\u003eHow do I use the VAGNEUS tester to find a coolant leak?\u003c\/h3\u003e\n\u003cp\u003eUsing the kit is a step-by-step process: pick the adapter that matches the radiator or expansion tank neck, connect the hand pump and gauge, then pressurize the system to the recommended value. Monitor the gauge for pressure drop; a steady loss of pressure points to a leak that must be traced and repaired.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003eChoose the correct radiator or cap-style adapter from the 13 included.\u003c\/li\u003e\n  \u003cli\u003eAttach the adapter to the filler neck or expansion tank securely.\u003c\/li\u003e\n  \u003cli\u003ePump to the vehicle’s specified pressure (commonly 0–35 psi) and observe the gauge for leaks.\u003c\/li\u003e\n  \u003cli\u003eIf pressure falls, inspect radiator, hoses, clamp joints, heater core, water pump and gasket areas.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat specific cooling-system problems can this kit diagnose?\u003c\/h3\u003e\n\u003cp\u003eThe VAGNEUS kit helps identify common failure points in a cooling circuit without disassembly.
