Oil Cooler - Failure

MODEL

Range Rover B.M.W Diesel Derivatives

DETAIL

Investigations by Land Rover engineers into failures of oil cooler units have shown that expansion of the intercooler is placing additional strain on the oil cooler which may result in oil cooler failure. To overcome this issue and to prevent undue strain being placed on the oil cooler, a new unit has been introduced with the addition of a sliding joint (on the slotted side of the oil cooler) to relieve any strain occurring. In the event of an oil cooler failure, the new condition oil cooler with the sliding joint should be fitted.

ACTION REQUIRED

In the event of an oil cooler failure the new condition oil cooler with sliding joint should be fitted following the process detailed below.
