1. Spark Plugs:
* Replacement: This is arguably the most important part. Spark plugs wear out and need replacing according to the manufacturer's recommended interval (check your owner's manual). Use the correct type and gap specified in the manual. Incorrect plugs can severely impact performance and fuel economy.
* Inspection: Before replacing, inspect the existing plugs for wear, fouling, or damage. This can give clues about other potential problems.
2. Wires (Ignition Cables):
* Inspection: Check for cracks, fraying, or corrosion in the ignition wires (spark plug wires). Replace any damaged wires. Damaged wires can lead to misfires and poor performance.
3. Air Filter:
* Replacement: A clogged air filter restricts airflow to the engine, reducing performance and fuel economy. Replace it with a new filter of the correct type. Frequency depends on driving conditions; check your owner's manual or consider replacing annually or every 12,000-15,000 miles.
4. PCV Valve (Positive Crankcase Ventilation):
* Inspection/Replacement: A faulty PCV valve can lead to increased engine wear and oil consumption. Inspect it for proper operation and replace if necessary. It's a relatively inexpensive and easy part to replace.
5. Fuel Filter:
* Replacement: A clogged fuel filter restricts fuel flow, leading to poor engine performance. The replacement interval is longer than the air filter, often every 30,000-60,000 miles (check your owner's manual).
6. Throttle Body Cleaning:
* Cleaning: The throttle body can become clogged with deposits, affecting engine responsiveness. Cleaning it with a throttle body cleaner (following the instructions carefully) can improve performance.
7. Mass Airflow Sensor (MAF) Sensor Cleaning:
* Cleaning: The MAF sensor measures the amount of air entering the engine. A dirty sensor can lead to poor performance. Clean it carefully with a MAF sensor cleaner (following instructions precisely, as these sensors are delicate).
8. Checking Fluids:
* Engine Oil: Check the oil level and change it according to the recommended intervals (check your owner's manual). Use the correct type and weight of oil.
* Coolant: Check the coolant level and condition. Top off if necessary and replace if needed based on your vehicle's age.
* Brake Fluid: Check the brake fluid level and condition. Flush and replace brake fluid as recommended.
* Power Steering Fluid: Check and top off as needed.
Important Considerations:
* Owner's Manual: Always consult your 2002 Ford Escape's owner's manual for specific maintenance schedules and recommendations. It's your best source of information.
* Professional Help: If you're not comfortable performing these tasks yourself, take your Escape to a qualified mechanic. Some procedures, like replacing the fuel filter, can be challenging.
* Year and Engine: The specifics of your tune-up might vary slightly depending on the exact engine in your 2002 Ford Escape (it had a few options).
This list covers the major aspects of maintaining your 2002 Ford Escape. Remember that regular maintenance is key to prolonging the life and performance of your vehicle. Don't neglect these items, as neglecting them can lead to more serious and costly repairs down the line.
