The ESOC Series CEX-550 Coolant Extraction System is a pneumatic tool that uses two hoses to connect to the top and bottom of the coolant system or radiator via quick connect fittings and can be used to perform coolant pressure or vacuum tests. The CEX-550 uses a two-stage filling process and it automatically stops coolant flow when the first stage is complete. This system can be used on both heavy and light duty engines and optional adapters are available for both drain and fill. This process insures no air pockets in the coolant system, according to the company.
