5. Lift the inserts. Flush and clean them internally
and externally. Use suitable brushes. Clean
housing as well.
Note: Ensure that no contaminants enter the en-
gine’s inlet manifold via the charge air coolers
(CAC).
6. Install the inserts in the housings. NOTE! En-
sure that the inserts are installed in the cor-
rect position. The locating lugs beneath the in-
serts’ upper flange should face outwards (from
the engine) and fit corresponding notches in the
housings, see illustration.
7. Locate the sealing strips on the inserts’ baffle
plate and reinstall the covers together with the
connecting pipes between the covers. Use new
sealing rings.
Note: The covers must be installed with the re-
cess on the cover’s flange facing forwards, see
illustration.
8. Install the O-rings and clamping rings beneath
the housings. Reinstall the coolant pipe between
the seawater pump and the heat exchanger, or
between the charge air cooler and the reverse
gear’s oil cooler. Use new sealing rings.
Reinstall the cover plate over the heat exchang-
ers and charge air coolers (CAC).
9. Fill the engine with coolant and vent the system
as described on page 55.
10. Open the sea cock and start the engine. Check
for leaks.
Oil cooler, reverse gear
Z. Zinc anode
Cleaning oil cooler, reverse gear
Close sea cock before working on cooling
system.
1. Open the drain cock on the oil cooler. Remove
the cooling water pipes to and from the oil cooler.
2. Remove both end covers and push out the insert.
(The insert can only be pulled out to the left as it
has a flange on this side.)
3. Wash the insert in (e.g.) white spirit and blow it
dry using compressed air (or let it stand and dry).
Clean the tubes internally and the ends of the
core using suitable brushes. Clean the housing
too.
4. Reinstall all parts in the opposite order. Use new
sealing rings.
5. Close the drain cock and open the sea cock.
Start the engine and check for leaks.
TAMD71, TAMD72: Heat exchanger/charge air
cooler (CAC)
Checking/replacing zinc anode(s)
Close sea cock before working on cooling
system.
1. Open the drain cock on the reverse gear’s oil
cooler.
2. Unscrew the zinc anode (Z) on the oil cooler’s
right end cover.
3. TAMD63: Unscrew the zinc anode in the heat
exchanger’s front end cover, or in the charge air
cooler’s rear end cover.
Note: The seawater in the heat exchanger or
charge air cooler should be drained at the same
time.
