Engine Coolant System Pressure Tester
More adapter kits available
Includes the most common radiator and cap adapters
The MotoRad MT-300 cooling system pressure tester is the professionals’ choice when it comes to testing vehicle cooling systems and coolant caps. This tester ensures an automotive cooling system is operating at the correct pressure for optimal performance. Made from high quality materials to ensure life-long durability. Designed to not only test the system, but also coolant caps. Over time, coolant cap seals, springs and valves can wear out causing a loss in system pressure. The MT300 provides quick diagnoses of cooling system issues.
Offers a large color coded gauge with reading up to 30pounds
The gauge facing will give you accurate reading in kpa. and pounds
As a safety feature there is a pressure release bar that when turned, it will release the pressure in the radiator neck or the Radiator cap for easy release
