How to Service the Power Steering Cooler on Mercury Mountaineer?

Raising the vehicle and supporting it first will start the process of servicing the power steering cooler. The power steering gear-to-cooler hose requires disconnection by loosening its clamp to drain fluid into an appropriate container. After disconnecting the cooler-to-reservoir hose, you should loosen its clamp. Start the process by unfastening the bolts which secure the power steering cooler. Attach the gear-to-cooler hose to the top inlet position and the cooler-to-reservoir hose to the bottom outlet of the power steering cooler when reinstalling it. Perform a leak test after filling and purging the system before finishing with a reverse order of removal steps for proper operation verification.
