Fit the oil lines
Fit the 2 brass male fittings to the inlet and outlet of the cooler as shown above– apply a
smear of pipe sealing compound to the threads and tighten firmly into the cooler. Do
not
over
tighten, as the brass threads can strip if excess pressure is applied.
Remove the spin-on oil filter and fit the adaptor (circled above left) under it with the O-ring
side towards the engine block. Apply a smear of clean engine oil to the O-rings on the adaptor
and the oil filter, refit the oil filter and tighten gently until resistance is felt as the seal first
contacts the housing and then tighten exactly one full turn from that point.
Absolute cleanliness is required here: there must be no dirt or contaminants anywhere near the
oil filter or adaptor fitting area.
Size the blue oil line by holding one end beside the fitting on the right-hand side of the oil
cooler and cutting to length to fit the rear adaptor fitting as shown above right.
Repeat the process for the other side of the oil cooler to the front adaptor fitting and then cut 2
lengths of fireproof sleeve to the same length as the oil lines and fit them over the oil lines.
