COOLERS
Fig. 4.3
Compressor oil cooler (1), engine coolant cooler (2) and engine
oil cooler (3)
Keep the coolers (1), (2) and (3) clean to maintain the cooling
efficiency.
Then clean by air jet in reverse direction of normal flow.
Steam cleaning in combination with a cleansing agent may be applied.
Close the service door(s).
In case of a mix of different coolant products this type
of measurement might provide incorrect values.
Remove any dirt from the coolers with a fibre brush.
Never use a wire brush or metal objects.
To avoid damaging the coolers, angle between jet and
coolers should be approx. 90 °.
(do not use jet at max. power)
Protect the electrical and controlling equipment, air
filters, etc. against penetration of moisture.
Never leave spilled liquids such as fuel, oil, water and
cleansing agents in or around the compressor.
Caution: do not top off when the engine is hot.
