DESCRIPTION AND OPERATION
ENGINE OIL COOLER
Description
The engine oil cooler is located in front of the radiator,
below the intercooler, and comprises a two pass,
single row matrix with twelve internal cooling tubes.
Pre-formed feed and return pipes/hoses are used to
link the oil filter housing and oil cooler, as shown in
26M7032.
Engine oil cooler
1. Engine oil cooler
2. Oil filter
3. Feed pipe
4. Return pipe
Operation
When the engine reaches its normal operating
temperature, oil, drawn through a steel strainer in the
sump, is pumped under pressure from the filter
housing (2) to the oil cooler (1) via the feed pipe (3).
Ambient air, forced through the front grille of the
vehicle and assisted by the pull of the viscous fan, is
dispersed across the oil cooler. The cooled oil then
passes through a return pipe (4) to the filter housing
before being distributed by the oil pump to the various
internal engine components.
