UniTest 70802 Universal Cooling System Radiator Pressure Tester 0-30psi

The UniTest 70802 is a universal cooling system pressure tester designed to identify leaks in radiators, header tanks and associated cooling-system components without requiring vehicle-specific adaptors.

Its inflatable bladder attachment seals inside threaded or bayonet-style filler necks, allowing the cooling system to be pressurised using the hand pump and monitored through the integrated pressure gauge.
