To replace the Power Steering Cooler pipe/hose (GT4), first, attach a drain pan under the vehicle and raise and support it. Detach Power Steering Cooler hose from
Power Steering Pump and power steering gear and cap the ends of this cooler so as to avoid dirt entry. Remove the Power Steering Cooler mounting bolts and take out the cooler from the vehicle. For installation, refit the Power Steering Cooler back and fit the mounting bolts, tighten to 5nm (44lt) connect the Power Steering Cooler hose to the power steering gear with the hose fitting being tightened to 33 n.m (24 lb in) and then connect the hose to the Power Steering Pump. Bleed the power steering system and lower the vehicle before removing the drain pan.
