Why does my Montero Sport’s check engine light come on when I start it?

Squealing can indicate a loose fan belt, and grinding could be a sign that something is wrong with your brakes — not the engine.

What could damage my Mitsubishi Montero Sport engine?

Can I put water in my Mitsubishi Montero Sport radiator?
