Replacing a serpentine belt on your 1986 Lincoln Town Car is a relatively straightforward task that you can usually complete in about 30 minutes. Here are the general steps involved:
1. Gather Necessary Tools:
- Replacement Serpentine Belt
- Ratchet
- Socket Set
- Extension
- Replacement Belt Tensioner (if needed)
2. Locate the Serpentine Belt:
- The serpentine belt is the single, long belt that wraps around the pulleys of your engine's components, such as the alternator, power steering pump, and air conditioning compressor.
3. Locate and Release the Tensioner:
- The serpentine belt tensioner is a pulley with a spring-loaded arm. It is usually located near the belt's path.
- Push down on the tensioner with the socket and ratchet to release its tension and loosen the belt.
4. Remove the Old Belt:
- With the tensioner released, you should be able to slip the old belt off the pulleys and remove it from the engine.
5. Check and Inspect Pulleys:
- Inspect the pulleys and idler wheels for any damage or wear, especially if the belt has snapped. If any worn or damaged components are found, replace them before installing the new belt.
6. Install New Belt:
- Start with one of the end pulleys and wrap the new belt around according to the correct diagram.
- Make sure the belt sits properly in all grooves on the pulleys.
7. Tension the Belt:
- Push down on the tensioner once more to take up the slack and tension the belt. Ensure the belt is taut but not overly tight.
8. Double-Check Route and Tension:
- Double-check that the belt is properly routed according to the diagram and make sure the belt tension is still correct. It should be firm with a slight give.
9. Finalize Installation:
- Release the tensioner slowly and allow it to lock in place.
10. Double-Check Operation:
- Start your car and check if the belt is smoothly rotating without slipping or squealing.
11. Verify with Drive:
- Take your car for a short drive to ensure the belt doesn't slip or cause any unusual noises.
If the belt performs properly and there are no additional problems, you've successfully changed the serpentine belt on your 1986 Lincoln Town Car. Always refer to your vehicle's service manual for specific instructions related to your model and any safety precautions that may apply.
