The cooling system is another vital area to maintain. Check the coolant level and condition, and flush the system as recommended in your owner’s manual. This helps prevent overheating and keeps your engine running smoothly. The electrical system needs periodic checks as well. Inspect the battery terminals for corrosion, and make sure all the lights are working correctly. If you experience any electrical problems, it's always best to seek professional help. Routine maintenance also includes checking and replacing air filters. A clean air filter improves engine performance and fuel efficiency. It is also important to regularly inspect the tires.
