Why does my Nissan engine sound different?

Strange under-the-hood noises can point to problems within your Nissan Pathfinder engine. Tapping or knocking could mean you're low on oil. Whistling could mean a belt is misaligned or there's an intake leak. Squealing can indicate a loose fan belt, and grinding could be a sign that something is wrong with your brakes — not the engine.

Can I add water to my Nissan Pathfinder radiator?
