Place a container under the oil cooler in order to collect any engine oil or coolant that drains from the oil cooler. Remove one of the oil hoses. Do not remove both of the oil hoses at the same time in order to ensure that cooling plate (3) remains fastened to cover plate (1) when cooling plate assembly (9) is removed. Before the second oil hose is removed, install the two-piece flange (7) and the nuts on the studs for flange (5) without the oil hose.
Remove the nuts and bolts for cover plate (6). Remove assembly (9). Remove O-rings (4) from the connectors of the oil hoses.
Thoroughly clean the flange face of the cover plate and the cylinder block. If a sealant was used in order to create the gasket, thoroughly remove the sealant from the surfaces of the cylinder block and cooling plate assembly (9). When the cooling plate assembly is reassembled, use new paper gasket (10).
Place cooling plate assembly (9) on a clean work surface. Remove four nuts (5) that retain the two-piece flanges for the oil hoses. Remove cover plate (1) from four studs of cooling plate (3).
Remove the O-rings (2). When the oil cooler is reassembled, these O-rings must be replaced with new O-rings.
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.
Inspect the cooling plate (3) for cracks and dents. Replace the cooling plate if cracks or dents exist. If necessary, clean the outside of the cooling plate and clean the inside of the cooling plate. Use a solvent that is not corrosive on copper. Ensure that no restrictions for the flow of lubricating oil exist in the cooling plate.Dry the cooling plate with low pressure air. Flush the inside of the cooling plate with clean lubricating oil.
If the studs (8) were removed from the cylinder block, clean the threads. Place Loctite 270 on the threads of the stud which are threaded into the cylinder block.
Place a new gasket (10) on the studs (8). Do not use any sealant on the gasket. Place the assembly (9) on the cylinder block. Tighten the nuts and bolts for the cover plate (6) to a torque of 22 N m (16 lb ft).
Clean the seats for the O-rings (2). Install new O-rings for the hose connections. Note: Do not remove the two-piece
