Check that oil inlet pressure is correct or measure the
differential between drains on the oil cooler shell.
Oil Cooler Temperature Differential (Air–Cooled
Radiator) – The oil temperature differential depends
on the temperature of the air at the oil cooler fan and
cleanliness of core faces. As ambient temperatures
and core restrictions increase, the oil cooler outlet tem-
perature will increase. The oil inlet temperature is
approximately the same as air discharge temperature
– see the gauge on the instrument panel. The outlet oil
temperature may be checked by installing a tee at the
oil filter outlet.
Oil Cooler Temperature Differential (Water–Cooled
Heat Exchanger) – The oil temperature differential de-
pends on the inlet water temperature and the water flow
rate permitted by the water flow control valve setting.
The oil inlet temperature is approximately the same as
the air discharge temperature – see the gauge on the
instrument panel. The oil outlet temperature may be
checked by installing a tee at the oil filter outlet.
Oil Cooler Water Pressure Differential (Water–
Cooled Heat Exchanger) – The water pressure differ-
ential through the heat exchanger will depend on the
supply pressure, flow rate, cooler tube cleanliness and
outlet pressure. The inlet and outlet water pressure
may be checked at the pipe fittings supplied by the cus-
tomer.
