DESCRIPTION AND OPERATION
Gearbox oil cooler
The gearbox oil cooler is located below the engine oil
cooler in front of the radiator and comprises a single
row matrix. On vehicles fitted with manual gearboxes
three internal cooling tubes are used, on vehicles with
automatic transmission a larger matrix, incorporating
twelve coolant tubes is fitted. Pre-formed feed and
return pipes/hoses are used to link the gearbox and oil
cooler.
Oil is pumped under pressure from the gearbox
through the feed pipe into the oil cooler. Ambient air,
forced through the front grille of the vehicle and
assisted by the pull of the viscous fan, is dispersed
over the oil cooler. The cooled oil then passes through
the return pipe, which is routed under the engine to
run parallel with the feed pipe back to the LH side of
the gearbox.
