Strange under-the-hood noises can point to problems within your Mercury Cougar engine. Tapping or knocking could mean you need an oil change. Whistling could mean a belt is misaligned or there's an intake leak. 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.
