DESCRIPTION AND OPERATION
GEARBOX OIL COOLER - MANUAL
Description
The gearbox oil cooler on manual vehicles is an
integral part of the radiator and is a brass concentric
tube type. The cooler is immersed in a separate water
tank at the base of the radiator. The inner core, which
has its own water jacket within the cooling tube,
carries the transmission oil via feed and return pipes,
see 26M7033.

Operation
Oil is pumped under pressure from the gearbox
through the feed pipe (3) into the tube (2) of the oil
cooler tank. With a combination of water and ram air
cooling, through the front grille of the vehicle and
assisted by the pull of the viscous fan, the cooled
transmission oil is routed back to the gearbox via the
return pipe (4), to repeat the cycle.
