Loss of power when accelerating and loud roaring noise. The heat quit working. It all started after I replaced water pump and fan clutch.

Good afternoon,

I would go over what you connected and disconnected and make sure you did not leave anything disconnected.

Check the mass air flow sensor and be sure it is plugged and and tight and secure.

Is the check engine light on?
