Cooling System Pressure Tester MV4534

Mityvac’s MV4534 is a professional-grade, automotive cooling system test kit. It quickly pinpoints external leaks, the most common cause of engine overheating, and aids in diagnosing internal leaks caused by a blown head gasket or cracked block or head. The kit combines a high-quality pressure pump with Mityvac’s universal cooling system adapter for quick, efficient and accurate testing, without the need for costly application specific adapters. The pump features a large-capacity stroke to quickly reach peak pressure and includes a 2½ in. diameter gauge with easy-to-read, color-coded test level indicators.
