Disclosure – This is a recommended process that we found online from other Lincoln Experts (John Cashman?) and have performed this task many times. Do it at your own risk. 

Step 1:  Flushing the Lincoln Continental Power Steering System

It is extremely important to flush the power steering system thoroughly in order to remove all contamination, particulates, and metals that have entered the system over the years. To do this requires putting the pressure side of the hose into a bucket of transmission fluid and an empty bucket on the return line so that you can flush your system properly. With the wheels of your car off the ground and your power steering pump removed, turn your steering wheel back and forth several times until no more old fluid and contaminants come out. Remember to have a container to catch the fluid. Dispose of the old fluid in a safe and responsible manner. When you’re sure that the system has been flushed out completely, you’re ready to install the rebuilt power steering pump.

Step 2: Installing the rebuilt power steering pump and bleeding it

• Install a new front engine seal

• Add transmission fluid to the reservoir until full (approximately one quart)

• With the wheels still off the ground, turn the steering wheel back and forth several times and check and refill the reservoir level

• Repeat this several times until you are sure that the system is full

• Next, start the engine and run for approximately five to six seconds 

• Stop, check fluid level again and top off the reservoir 

• Start the engine again for approximately ten to 15 seconds

• Stop, check levels, and refill as needed 

• Start the engine again and let it idle for several minutes, making sure that the wheels stay centered, and that they do not try and turn to one side or the other

• Next, gently turn the steering wheel from left to right, being extremely careful-not to lock the steering wheel in either direction for more than a fraction of a second

• Stop the engine. Check the power steering fluid levels and fill as needed. 

• Restart the engine and let it run for several minutes to give the system a chance to remove any air blockages that may occur. This is a good time to turn on any 7 hydraulically operated systems, such as the wiper motor, with the wiper arms and blades removed. Turn off the engine, wait five 10 10 minutes, put the car on the ground, and go for a ride. 

• Pay attention to any unusual whining or groaning of the system. It could be a sign of a problem.

• After you’ve taken your ride, let the car sit for a period of time. Then check for any leaks or drips under the engine.
