Steps
Remove the front bumper
Release the wheel-well and lower splash shield fasteners, then remove the corner bolts. Disconnect the fog lamp and marker light wiring and carefully pull the bumper forward from its fender clips.
Drain the power steering fluid
Raise and support the vehicle and place a drain pan underneath. Pump fluid from the reservoir, then disconnect the upper hose and allow remaining fluid to drain.
Remove the old cooler
Loosen the hose clamps and pull the hoses from the cooler while catching fluid. Release the cooler retaining clips and remove the cooler from its mounts.
Install the replacement cooler
Seat the new cooler in its retaining clips and reconnect both hoses. Position the clamps over the hose ends and tighten them securely without damaging the hoses.
Reinstall the bumper and bleed the system
Reconnect the bumper wiring and align its tabs with the fenders. Reinstall the bolts, clips, and lower shield, then refill with the specified fluid and turn the steering slowly from side to side until the system is quiet and the level stabilizes.
Check your vehicle’s repair manual for exact specifications and fit.
