VALLEY PAN INSTALLATION

Valley Pan

- Spend a bit more time cleaning up the area, keeping debris from entering the coolant in the block (and the intake ports). Carefully clean the valley pan sealing

surface - use a light solvent (eg., WD40) on a paper towel to wipe clean. I also ran a piece of 2,000-grit sandpaper over this surface as insurance. The surface

should be nice and shiny when suitably clean.

- Dork Alert! Attach the new heat shield to the new valley pan PRIOR to installation of the pan: failure to do so will require removal of the pan, as the shield will

not fit past the knock sensors if the valley pan is already installed. Take care when handling the new valley pan not to disturb the attached seal.

- Clean all twenty bolts. Apply a small drop of threadlok to each bolt, near the bottom.

- Install valley pan/heat shield - it only fits one way. Loosely install two bolts, one on each side, in the middle of the block. Loosely install two bolts, one on each

end, to align pan. Once you are sure the pan is aligned, snug but do not tighten the first two bolts.

- Install the remaining sixteen bolts, working from the center outward, snugging each bolt, but do not tighten. When all twenty bolts are snug, tighten each, again

working from the center outward.
