Automotive Cooling System Testers

Tool Shack Web has the automotive test tools you need to diagnose problems with coolant systems. Start with one of our vehicle coolant system testers, which makes it easy to check the freezing point of the engine’s antifreeze. Tracing leaks? We have charge air cooler testers to pressurize the coolant system, as well as accessories for coolant system tester machines, so you can connect to any radiator cap opening. If you think the car has a leaking head gasket, we have strips to test for combustion compounds in the coolant. Using our automotive vacuum test kits, you can quickly purge coolant, remove trapped air bubbles and get a complete fill on difficult cooling systems, including those used on mid-engine cars.
