Here's a general guide, but this is not a substitute for a repair manual specific to your 1995 Ford Falcon's engine. You need to consult a workshop manual for your specific model and engine type (e.g., 4.0L inline-6, etc.) to get the exact location and procedures. Variations exist between models.
Before You Begin:
* Safety First: Let the engine cool completely before starting any work. Coolant is hot and under pressure, and can cause serious burns.
* Gather Supplies: You'll need the correct replacement ECT sensor (get the part number from your local parts store using your car's VIN), a socket wrench (likely a 10mm or 12mm, but check your manual), rags, possibly a small container to catch coolant, and potentially some new coolant if you lose some during the process. You might also need penetrating oil if the sensor is stuck.
General Steps (Consult your manual for precise details):
1. Locate the ECT Sensor: This sensor is typically located on the engine block or cylinder head, often near the thermostat housing. Your repair manual will show the exact location.
2. Disconnect the Electrical Connector: Carefully unplug the electrical connector from the ECT sensor.
3. Remove the Sensor: Use the appropriate socket wrench to carefully unscrew the sensor from its housing. It might be tight, so use penetrating oil if needed. Be prepared for some coolant leakage.
4. Clean the Area: Clean the sensor mounting area on the engine block with a clean rag.
5. Install the New Sensor: Carefully screw the new ECT sensor into place, tightening it to the manufacturer's specified torque (found in your repair manual). Do not overtighten!
6. Reconnect the Electrical Connector: Carefully plug the electrical connector back onto the new sensor.
7. Check for Leaks: Carefully inspect the area for any coolant leaks. Top up the coolant if needed.
8. Start the Engine: Start the engine and let it run for a few minutes to check for any issues. Monitor the coolant temperature gauge.
9. Check Coolant Level: After the engine has cooled down, check the coolant level and top it up to the correct level as indicated on your coolant reservoir.
Important Considerations:
* Coolant Type: Use the correct type of coolant specified for your Ford Falcon. Mixing different coolants can be detrimental.
* Torque Specifications: Overtightening the sensor can damage the engine block threads. Always use the correct torque specification from your repair manual.
* Air Pockets: Air pockets in the cooling system can cause overheating. Refer to your repair manual for bleeding the cooling system if necessary.
Again, this is a general guide. You absolutely must consult a repair manual specific to your 1995 Ford Falcon to ensure you have the correct procedure and part number for your vehicle. Working on your car's cooling system can be dangerous if not done correctly. If you are unsure about any step, seek professional help.
