It is recommended to change the oil every 3,000 to 5,000 miles, depending on your driving conditions. Using synthetic oil can extend this interval. Always refer to the owner’s manual for specific guidance.
The recommended brake fluid for the 2004 Subaru Impreza WRX is DOT 3 or DOT 4. Always ensure the fluid meets the necessary specifications and check your owner’s manual for confirmation.
To reset the check engine light, disconnect the negative battery terminal for about 15 minutes. Reconnect it, start the car, and the light should be reset. If it persists, a diagnostic check is recommended.
The recommended tire pressure is typically 32 psi for the front tires and 29 psi for the rear tires. Always check the sticker on the driver’s side door jamb for the most accurate information.
To improve fuel efficiency, maintain proper tire pressure, use recommended oil, and ensure regular maintenance such as air filter replacements. Avoid excessive idling and aggressive driving.
If your car is overheating, pull over safely, turn off the engine, and allow it to cool. Check the coolant level once it’s safe. If necessary, add coolant and inspect for leaks. Seek professional help if the problem persists.
To replace the headlight bulb, open the hood, disconnect the electrical connector from the back of the headlight assembly, remove the rubber boot, and release the bulb retaining clip. Replace the bulb, ensuring not to touch the glass, and reassemble.
Symptoms of a failing turbo include a loss of power, excessive exhaust smoke, unusual noises from the turbo, and increased oil consumption. A check engine light may also illuminate.
To check the transmission fluid level, ensure the engine is warm and the car is on a level surface. Remove the dipstick, wipe it clean, reinsert it fully, then remove it again to check the level. The fluid should be between the “Full” and “Add” marks.
The timing belt should generally be replaced every 105,000 miles or 8 years, whichever comes first. Regular inspection for wear and tear is also advisable.
