Why is my Nissan Patrol overheating?

I noticed that my Nissan Patrol's temperature gauge is way above normal. What could be causing this and what should I do about it?

The first thing you should do is check the coolant level and make sure it is topped up. If the level is low, it could be a sign of a leak in the system. You should also check the radiator cap and hoses for any cracks or damage. If everything seems fine, then it could be a problem with the thermostat or water pump.

Another common cause of overheating in Nissan Patrols is a faulty radiator. It could be clogged with debris or have a leak. It's important to get this checked and replaced if necessary to prevent further damage to your engine.

If you have recently replaced the coolant and the problem still persists, it could be an issue with the head gasket. This may require professional help to fix.
