18 Split the cooler assembly into 3 parts
(A-bank, B-bank
and central connector).
19 Remove the end covers (25) of the air coolers,
see Fig 15-8.
15.5.3 Cleaning of air cooler
Clean air cooler heat exchange surfaces are essential for a long
and trouble-free engine operation. The cleaning should be done
in regular intervals following the pressure drop (
D
p) over the
charge air cooler.
1 Remove the cooler
according to section 15.5.2.
2 Clean the air side of the cooler
by immersing the air
cooler in a chemical cleaning bath for at least 24 hours. See
chapter 02 for approved cleaning detergents.
The best cleaning effect is achived if the cleaning tank is equipped
with perforated pipes, see Fig 15-9. During cleaning, steam or
pressurized air is fed through the pipes. When cleaning is com-
pleted, the cooler should be flushed thoroughly with water.
Note!
The use of a high pressure water jet for flushing, should be
avoided because:
- it will pack the dirt into the middle of the cooler
- the cooler fins will be damaged
This will cause lowered air cooling efficiency.
3 Clean the water side
by immersing the tube bundle into
a chemical cleaning bath for at least 24 hours. Follow the
recommendations given for the air side.
4 Mount the cooler on the engine
according to section 15.5.5
