BFCA Posted August 17, 2015 Share Posted August 17, 2015 Hi All - Replaced timing belts, idler , tensioner etc. Drove the car 300 miles and let it sit for a day.Got back in and heard a distinctive hi pitched whine, lower at idle higher at speed coming from engine. Not discernable at freeway speed (too high pitched?). Got back in the car the following day and didnt hear the noise. The noise was way too obvious to be "normal". If I knew more I might suspect a problem with the alternator...but then it could be any of the other items replaced? Any thoughts would be most welcome!

lstevens76 Posted August 17, 2015 Share Posted August 17, 2015 The first thing I would do is check all the belts and make sure they're correctly tight. Then while it is running I would look at the crank pulley and make sure it's not moving. 1 Link to comment Share on other sites More sharing options...
desertsubaru Posted August 17, 2015 Share Posted August 17, 2015 Did you change the water pump? Link to comment Share on other sites More sharing options...
BFCA Posted August 17, 2015 Author Share Posted August 17, 2015 Yes I changed the water pump. Not sure why it would be so obvious and then go away ... Link to comment Share on other sites More sharing options...
1 Lucky Texan Posted August 17, 2015 Share Posted August 17, 2015 change the air filter? check the tabs on the far end of the box. you can run the car briefly with the belts off. many people find air in the power steering after they've 'disturbed' the hose. look for bubbles/foam in the tank while idling.
