How to properly maintain my Toyota Camry's engine?

I've been noticing my Toyota Camry's engine making strange sounds and I'm not sure how to properly maintain it. What are some steps I can take to ensure my engine stays in good condition and doesn't cause any issues in the future?

Regularly change your engine's oil and filter to keep it running smoothly and prevent any potential damage. It's recommended to do this every 5,000 miles or as per your vehicle's manual.

Pay attention to any warning lights on your dashboard and get them checked out by a certified mechanic if they appear. Ignoring them could result in more serious engine problems.

Keep an eye on your engine's coolant levels and make sure to refill it if it's low. Low coolant levels can lead to overheating and potential engine damage.
