How to properly maintain the radiator in my Nissan Patrol?

I recently noticed my Nissan Patrol's radiator is starting to look a little rusty. How can I ensure it lasts longer and doesn't cause any damage to my car?

Regularly check for any rust or corrosion on your radiator. If you see any, take your car to a mechanic as soon as possible to prevent any further damage.

Flush your radiator system and replace the coolant every 2-3 years. This will help remove any built-up debris and prevent overheating.

Make sure to keep the radiator cap tightly sealed and regularly check the coolant level. Low coolant can cause your engine to overheat.
