The recommended oil type for a 2003 Mazda Protege 5 is 5W-30, which is suitable for most climates.
It is advisable to replace the timing belt every 60,000 to 100,000 miles to prevent potential engine damage.
The recommended tire pressure is 32 psi for both front and rear tires.
To reset the Check Engine Light, disconnect the battery for about 15 minutes, then reconnect it. If the light persists, have the vehicle checked for error codes.
Common issues include transmission slipping and rough shifting, often due to low transmission fluid or worn components.
To replace the headlight bulb, open the hood, disconnect the power connector from the bulb, remove the rubber boot, unclip the bulb, and replace it with a new one. Ensure it's securely fastened before reconnecting the power.
At 100,000 miles, it's recommended to check and possibly replace the timing belt, inspect the water pump, replace the spark plugs, and perform a comprehensive inspection of the vehicle's systems.
Improving fuel efficiency can be achieved by maintaining proper tire pressure, performing regular engine tune-ups, using high-quality fuel, and ensuring the air filter is clean.
Mazda recommends using a high-quality ethylene glycol-based coolant to prevent corrosion and overheating.
Poor acceleration can be caused by a clogged air filter, faulty spark plugs, or issues with the fuel delivery system. A diagnostic check can help identify the specific issue.
