four cylinder turbocharged engines

To dismantle
1 Remove the oil cooler from the cylinder block , see
operation 21-11 .
2 Release the setscrews and remove the cover.
3 Release the self-locking nuts at the back of the oil
cooler and remove the cooler element.
4 Clean the element and check for cracks. If a
solution is used to clean the outside of the element,
ensure that this does not enter the element. Check
that there is nothing to restrict the flow of lubricating
oil through the element of the oil cooler. If the inside
of the element needs to be cleaned, use a solvent
which is suitable for copper. Dry the element with low
pressure air and then flush it with clean engine
lubricating oil.

the element and the self-locking nuts for the studs.

locking nuts to 22 Nm (16 lbf ft) 2,2 kgf m.

and tighten the setscrews to 11 Nm (8 lbf ft) 1,1 kgf m.
