To reset the check engine light, disconnect the negative battery cable for about 15 minutes. Reconnect it, and the light should be reset. If the light returns, it's best to diagnose the issue using an OBD-II scanner.
The recommended oil type for the 2004 Acura RSX is 5W-20. The engine oil capacity with a filter is approximately 4.4 quarts (4.2 liters).
To replace the cabin air filter, open the glove box and remove the retaining arms. Then, remove the filter cover and replace the old filter with a new one, ensuring the airflow direction is correct.
Check the transmission fluid level and condition. If it's low or dirty, consider a fluid change. Persistent issues may require professional inspection or a transmission rebuild.
Ensure regular maintenance such as timely oil changes, air filter replacements, and proper tire inflation. Driving habits like smooth acceleration and maintaining a steady speed can also improve fuel efficiency.
Engine knocking could be due to low-quality fuel, carbon buildup, or issues with the spark plugs. Try using higher octane fuel and check the condition of spark plugs. Persistent knocking should be evaluated by a mechanic.
Open the hood and locate the back of the headlight assembly. Twist and remove the bulb holder, replace the old bulb with a new one, and reassemble. Ensure not to touch the glass of the new bulb with bare hands.
Squealing brakes can be caused by worn brake pads, glazing, or debris on the rotors. Inspect the brake pads for wear and replace if necessary. Cleaning the rotors can also help resolve the issue.
Check the coolant level and look for leaks in the radiator and hoses. The thermostat and radiator fan should also be tested to ensure they are functioning correctly. Persistent issues may indicate a water pump problem.
Follow the manufacturer's maintenance schedule, which typically includes oil changes every 5,000-7,500 miles, tire rotations, brake inspections, and fluid checks. Refer to the owner's manual for detailed intervals.
