ENGINE FLUSH
The engine can be flushed with a chemical additive with the MCX-2F connected as
described in preceding pages. Two valves located on the front panel each have two
positions - EXCHANGE and BYPASS.
When the valves are both turned to the BYPASS position the coolant in the vehicle
bypasses the MCX-2F. It flows through the green and black hoses which are connected
together inside the MCX-2F by the two valves being in the BYPASS position.
Flush (or leak sealant) additives can be added to the vehicle cooling system through
the radiator fill port. The engine can then be started to circulate the additives throughout
the cooling system.
Connecting the MCX-2F to the cooling system prior to adding additives and running the
engine eliminates the need to make connections involving hot coolant.
