Tools You'll Likely Need:
* Socket wrench set (metric)
* Screwdrivers (Phillips and flathead)
* Pliers
* Wire brush (for cleaning contacts)
* New ignition module (make sure it's the correct part for your engine)
* Possibly a multimeter (for testing the old module and confirming proper installation)
* Shop rags or paper towels
Steps (General):
1. Disconnect the Battery: This is crucial to prevent electrical shocks and damage. Disconnect the negative (-) terminal first.
2. Locate the Ignition Module: The location varies slightly by year and engine type. On many Ford Tempos, it's mounted on the distributor or near the distributor on the engine. Your repair manual will show the exact location.
3. Disconnect Electrical Connections: Carefully disconnect any wiring harnesses connected to the ignition module. Take note of their positions or take pictures so you can reconnect them correctly. A wire diagram from your repair manual will be invaluable here.
4. Remove the Ignition Module: Depending on how it's attached, this might involve removing mounting screws or bolts. The module is usually held in place with a few screws or clips.
5. Clean Contacts: Use a wire brush to clean the contacts on both the module and the wiring harness connections. This helps ensure a good electrical connection with the new module.
6. Install the New Ignition Module: Carefully align the new module and secure it in place using the mounting hardware. Ensure it's firmly seated.
7. Reconnect Electrical Connections: Reconnect the wiring harnesses, making sure each wire is in its correct location. Reference your diagrams or pictures if needed.
8. Reconnect the Battery: Carefully reconnect the battery's positive (+) terminal.
9. Test the System: Start the engine and check for proper operation. Listen for any unusual noises and ensure the engine runs smoothly. If you have a multimeter, you can test the ignition system for proper voltage and signal to verify correct installation.
Important Considerations:
* Year and Engine: This is crucial! A repair manual specific to your Ford Tempo's year and engine is essential. The location and installation procedure can vary significantly between model years and engine types.
* Distributorless Ignition Systems (DIS): Some later-model Tempos may have a DIS system where the ignition module is integrated differently. The procedure will differ slightly.
* Professional Help: If you're uncomfortable working on your car's electrical system, it's best to take it to a qualified mechanic. Improper installation can lead to serious damage to your vehicle.
Remember: This is a general guide. Always consult a repair manual specific to your Ford Tempo for detailed instructions and safety precautions. Failing to do so could lead to damage to your vehicle or personal injury.
