CLEANING THE COOLING SYSTEM

Note:

If necessary, the cooling system should be cleaned more often.

External cleaning

Heat exchanger

Drain the coolant from the engine, see “Changing coolant”.

Close the bottom valve or valves and drain the seawater circuit.

Disconnect the heat exchanger’s seawater pipe connections and the con-
nections to the charge air coolers, oil cooler and block.

Remove the heat exchanger assembly and dismantle it as illustrated.

Clean the outside of the element. Use a paraffin-based engine cleaner.

Remove any deposit on the inside of the pipes using a round file.

Assemble the heat exchanger. Change damaged and hardened O-rings.

Make sure that the thermostats are in place and fit the heat exchanger
back in place on the engine. Reconnect the pipes to the charge air cool-
ers and oil cooler and also the return line from the block.

Fill the system with coolant as described in the specifications on
page 32.

There are springs and retainers

in the heat exchanger, between

the housing and the element,

which are not illustrated.

The cooling system must never

be cleaned with caustic soda.

There is a risk of damage to

aluminium parts.
