The installation process requires you to mount the Oil Cooler onto the radiator support using four bolts with a torque of 10 n.m which is equivalent to 89 lb in. Tighten the Oil Cooler lines to the auxiliary Oil Cooler using 23 n.m torque (17 lb ft). After draining the reserve fluid place the drain pan aside before putting back the grille assembly.
