1. Oil from oil pump
. Heat exchanger assembly
3. Oil from filter into engine
4. Cooled oil to paper filter
5. Delivery valve for piston cooling
6. Partial flow to centrifugal cleaner
From the oil pump, the lubricating oil flows via passages in the
block to the oil cooler located inside the front side cover on the
right-hand side of the block.
The oil cooler is a plate heat exchanger.
All the oil flows through the cooler where it is cooled by the cool-
ant from the cooling system.
An oil pressure valve (5) is located in the coil cooler housing for
cooling the pistons.
It has an opening pressure of 3 bar. No piston cooling therefore
takes place at low engine speeds (idling).
