Why does the check engine light come on when I start my Diamante?

Why is my Mitsubishi Diamante making engine noise?

Strange under-the-hood noises can point to problems within your Mitsubishi Diamante engine. Tapping or knocking could mean you're low on oil. Whistling sounds could mean you have an intake leak or misaligned belt. Squealing can be traced back to 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 Diamante engine?

Can I add water to my Mitsubishi Diamante radiator?

It’s not recommended you put water in your Diamante radiator unless it’s an emergency. Under normal circumstances, use a 50/50 mix of water and coolant or a pre-mixed coolant. But, if you need to keep driving while out of coolant, using water is better than driving with an empty coolant reservoir.
