- Disconnect the negative battery cable.
- Remove the reservoir cap and disconnect the return (lower) hose from the
fluid reservoir. Drain the fluid into a clean pan.
- Depending on the access for your particular vehicle, raise the vehicle and
support it safely on jackstands, if necessary.
- If the pulley is to be removed from the pump, loosen the bolts now. Leave
them finger-tight in place.
- Loosen the pump mounting bolts, move the pump towards the engine and remove
the belt. On 3.0L (24 valve) and 3.5L engine-equipped Monteros, loosen the
drive belt tensioner adjusting bolt, then remove the belt. Turn the pump by
hand to eliminate the fluid from the system.
- Disconnect the pressure hose at the top of the pump and the suction hose
at the side of the pump. Allow the fluid to drain into the container.
- Remove the pump attaching bolts and lift the pump from the brackets.
- When reinstalling, make certain the bracket-to-engine bolts are tight, then
install the pump to the brackets.
- If the pulley was removed, reinstall it and tighten its nuts securely.
- Install the drive belt and adjust its tension correctly — refer
to Section 1.
- Connect the pressure and return hoses. Make sure the hoses are not twisted
and do not contact any other parts so as to avoid chafing. When installing
the pressure hose, make certain that the notch of the fitting contacts the
suction connector of the oil pump. The pressure hose may use O-rings to help
it seal, remove the old ones and install new ones before installation.
- Pour power steering fluid into the reservoir to the lower mark, then bleed
the system.
- Inspect all the fluid line connections for any sign of leakage.
