Perform the following procedure in order to inspect the engine oil cooler:

  1. Place a container under the oil cooler in order to collect any engine oil or coolant that drains from the oil cooler.

  1. Remove the cover (4). Refer to Disassembly and Assembly, "Engine Oil Cooler - Remove" for removal of the engine oil cooler.

  1. Thoroughly clean the flange face of the cover and the cylinder block.

    ------ WARNING! ------

    Personal injury can result from air pressure.

    Personal injury can result without following proper procedure. When using pressure air, wear a protective face shield and protective clothing.

    Maximum air pressure at the nozzle must be less than 205 kPa (30 psi) for cleaning purposes.

    ----------------------

  1. Inspect the cooling plates (2) for cracks and dents. Replace the cooling plates if cracks or dents exist.

    If necessary, clean the outside and clean the inside of the cooling plates. Use a solvent that is not corrosive on copper. Ensure that no restrictions for the flow of lubricating oil exist in the cooling plates.

    Dry the cooling plates with low pressure air. Flush the inside of the cooling plates with clean lubricating oil.

  1. Replace the O-rings (3) and the gasket (1). Install the engine oil cooler. Refer to Disassembly and Assembly, "Engine Oil Cooler - Install" for installation of the engine oil cooler.

  1. Ensure that the cooling system of the engine is filled to the correct level. Operate the engine. Check for oil or coolant leakage.
