Here's a general outline. Specifics might vary slightly depending on the exact engine (3.8L V6 is common for this model). Always consult a repair manual specific to your vehicle's year and engine for precise instructions and diagrams:
1. Preparation:
* Gather Tools: You'll need a socket set (likely metric), wrenches, a screwdriver (possibly Phillips and flathead), and possibly a ratchet with extensions to reach the ICM. A shop manual with wiring diagrams is highly recommended.
* Locate the ICM: The ICM is usually mounted on the distributor itself. The distributor is located on the top of the engine, under the engine cover (if equipped).
* Identify the ICM Connector: Locate the electrical connector that plugs into the ICM.
2. Removal:
* Disconnect the Battery: This is crucial to prevent electrical shock and damage.
* Remove the Engine Cover (if applicable): Carefully remove any plastic engine cover to access the distributor.
* Locate and Disconnect the ICM Connector: Carefully unplug the electrical connector from the ICM. Take note of its orientation for correct reinstallation.
* Remove the ICM: Depending on the specific model, the ICM might be held on by screws or clips. Carefully remove these fasteners to release the ICM from the distributor. You may need to use extensions on your ratchet or wrenches to reach it.
* Inspect the ICM: Once removed, visually inspect the ICM for any obvious signs of damage, such as cracks, burns, or corrosion.
3. Installation:
* Install the New ICM: Carefully install the new ICM in the same position as the old one. Ensure it's securely fastened.
* Reconnect the ICM Connector: Carefully plug the electrical connector back into the new ICM, ensuring it's securely seated and oriented correctly.
* Reinstall Engine Cover (if applicable): Put the engine cover back on.
* Reconnect the Battery: Reconnect the negative battery cable.
4. Testing:
* Start the Engine: Try to start the engine. If it starts and runs smoothly, the ICM replacement was successful.
* Test Drive: Take the car for a short test drive to ensure the problem is resolved.
Important Considerations:
* Distributor Cap and Rotor: While you're in there, it's a good idea to inspect the distributor cap and rotor for wear or damage. These are relatively inexpensive and replacing them at the same time might prevent future issues.
* Professional Help: If you're not comfortable working on your car's electrical system or you're unsure about any step, it's best to seek professional help from a qualified mechanic. Incorrect installation could lead to further damage.
* Repair Manual: A repair manual specific to your 1996 Mercury Cougar XR7 is invaluable. It provides detailed diagrams, torque specifications, and troubleshooting steps.
This is a general guide. Always consult a repair manual specific to your vehicle before attempting any repairs. Improper procedures can lead to damage or injury.
