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.
Coolant bypasses MCX-2F when both valves are turned to BYPASS.
