Question about 2004 Mazda 6
My Mazda 6, 2.3L is making a horrendous loud humming or whining noise, I think at the exhaust intake, any ideas?
Most humming whinning noises come from the belt area and are caused by worn out bearings in pulleys. ( alternator,tensioner pulley. idler pulley etc ). I would remove the belt and spin all the pulleys one at a time with my hand to see if one is noisy and replace it if so
