Installation Procedure
Important:
• | Prior to the installation of the engine oil cooler hose/pipe assembly,
install NEW retaining clips to the quick connect fittings. |
• | Ensure that the oil cooler hose/pie assembly being installed has
plastic caps on the ends of the pipes. If no plastic caps exist, or the plastic
cap is damaged, obtain a new cap. Install the cap on to the cooler line prior
to cooler line installation. |
- Do not install the NEW retaining clips
onto the fitting by pushing on the clip.
Important: Failure to properly install the retaining clip could cause the cooler
line to come loose and cause damage to the engine.
- Install the NEW retaining clip into the quick connect fitting by using
your thumb and forefinger. Insert the new retaining clip into one of the three
fitting recesses. Ensure that the retaining clip is engaged in all 3 slots.
- With one end of the retaining clip engaged
in the connector fitting slot, use your thumb in order to rotate the retaining
clip around the connector fitting, until the retaining clip snaps into place.
- Ensure that the 3 retaining clips ears are seen from inside the
fitting and that the retaining clip moves freely in the fitting slots.
- Install NEW retaining clips into the remaining quick connect fittings.
- Install the oil cooler hose/pipe assembly
and a NEW gasket.
Notice: Use the correct fastener in the correct location. Replacement fasteners
must be the correct part number for that application. Fasteners requiring
replacement or fasteners requiring the use of thread locking compound or sealant
are identified in the service procedure. Do not use paints, lubricants, or
corrosion inhibitors on fasteners or fastener joint surfaces unless specified.
These coatings affect fastener torque and joint clamping force and may damage
the fastener. Use the correct tightening sequence and specifications when
installing fasteners in order to avoid damage to parts and systems.
