Installation
NOTE:Do not remove the black powder coating; simply scuff the surface in the following step.
1. Prepare the surface of the oil pan by scuffing the surface with a fine abrasive pad such as Scotch Brite(R).
2. Wipe oil pan flange and block surface with clean cloth. Use aerosol brake clean to remove all traces of oil (Surface must be oil free).
IMPORTANT NOTE
^ The exact location and width of the elastomeric sealant bead is critical in order to produce an oil-tight seal.
^ If using the Ivory White Hylomar(R) 101, allow the RTV bead to form a "skin" (about 2 minutes depending on the ambient temperature/humidity) before installing the oil pan to the block flange.
^ If elastomeric gasket maker (LRNA25223) is used, the pan may be installed immediately, but it must be installed within five minutes of applying bead.
3. Using recommended elastomeric sealant (Permatex(R) Elastomeric Gasket Maker or Hylomar(R) 101 Ivory White RTV), apply a 4 mm. (0.160 in.) bead on the oil pan flange in the path shown. Also apply sealant "circles" in the areas shown in figure 5. These "circles" should coincide with the joints in the sealing surface at the front cover and rear main bearing cap area.
4. Remove any old accumulated RTV sealant from the tips of the bolts or studs and clean thoroughly.
NOTE:
The front cover bolts/studs enter into an oil pressure cavity, so sealing is critical. Do not use a thread locking compound. Use a thread sealing compound such as Loctite(R) # 545, # 567.
5. Apply thread sealing compound to the front cover bolts/studs.
6. If Range Rover, install front cover studs.
7. Position oil pan and finger-tighten bolts.
8. Tighten bolts progressively in two stages in the sequence shown in figure 6.
^ Tighten to 10 Nm. (71 lbf ft.)
^ Tighten to 25 Nm. (18 lbf ft.).
9. If Range Rover, perform the following:
^ Raise lift and remove cross member support.
^ Lower lift.
10. Install screw holding dipstick tube to valve cover.
11. Refill engine with oil to the proper level.
12. Start engine and check for leaks.
