1. Replace the oil filter housing on the engine with the new housing which incorporates feed and return ports
for the oil cooler hoses. Transfer the oil filter canister. Fit the new blanking plug into the tapped hole in
the top of the housing. Using a thread sealant, screw the new adaptor elbow into the tapped hole on the
underside of the housing, and from the old filter housing, transfer the brown bodied oil pressure switch
into the elbow. Note: i) If a new VHPD engine is being fitted, tie back the unused black coloured harness
connector (oil pressure gauge transducer), ii) If the old oil pressure switch is the later, post Jan.'98 parallel
thread type, the earlier type tapered thread switch must be ordered and fitted - A111E6099S.

grommets into the hose routing holes.
3. Remove the lower centre three fasteners for the radiator air intake grille, and fit the oil cooler air intake
duct to the underside of the crash structure using the two fixings a the bottom of the towing eye strut. Rifit
