The Mastercool 43302 Cooling System Pressure Test Kit detects external system leaks and internal engine leaks from blown gaskets or cracked blocks. It includes blue and black radiator cap test connectors, a hand pump, a thermometer, and 21 adapters (numbers 2, 3, 4, 6–23) made to fit most popular domestic and import cars and trucks; however, since ATV radiator caps often differ, these adapters may not fit, so it's important to check your ATV’s radiator cap size.
