It is a very important part of the vehicles pollution-control system. The Lincoln Town Car PCV valve also helps the engine run efficiently, extending the life of your motor. Replacing the PCV valve in your vehicle is easy to do and should be done regularly to keep your car running smoothly. It can be replaced in less than 15 minutes.
How to Replace the PCV Valve in a Lincoln Town Car
Locate the PCV valve of your Lincoln Town Car on the top of the intake manifold under your air cleaner. The end of the PCV valve plugs into the top of the intake manifold and has two vacuum hoses attached to it.
Carefully disconnect the two vacuum hoses that are attached to the PCV valve to prevent the plastic outlet valves from breaking off. Remember which hose attaches to each outlet valve so you can reattach the hoses correctly on the new valve.
Unplug the PCV valve from the intake manifold by pulling it straight out of the manifold. Check the valve port to verify that there are no broken pieces left behind.
Plug the new PCV valve in to the intake manifold valve port until you hear the PCV valve click into place. Verify that it is seated properly in the manifold.
Reconnect the vacuum hoses to the PCV valve outlet ports and check the vacuum hoses to verify that there are no holes or leaks in them.
- Do not attempt to work on a hot vehicle. Allow the engine to cool completely before beginning any maintenance.
