baffle (A2) to control coolant flow.
To dismantle
1 Remove the oil cooler , see operation 21-12 .
2 Release the nuts on the front of the cover and
remove the element of the oil cooler (B).

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

pressure air and then flush it with clean engine
lubricating oil.
