A Cooling System Pressure Test Kit with a truly universal approach to testing vehicle cooling system pressure. The tester adapts to cooling system hoses from 1/4" to 5/8" in diameter. Find a coolant hose connection and insert the adapter to match hose diameter, couple the hand pump with integrated gauge to the adapter and you're ready to test. When finished, relieve system pressure by slowly loosening the cap on the 'degas" bottle. Eliminate the search for the right cap adapter and test cooling systems faster. 

The hand pump features an easy to read integrated pressure gauge, a padded base to set against vehicle surfaces without scratching and a 36" integrated hose with a quick-coupler mated to the adapters. The hose adapters use durable brass fittings and include a banded spring clamp for easy attachment. A radiator cap adapter with quick connect fitting is included for older vehicles. Every adapter includes a Schrader valve to prevent spray when disconnecting.

This Cooling System Pressure Test Kit covers virtually any make and model that enters your shop and is stored in convenient blow molded case. Covered by OTC's Lifetime Warranty.
