Re: Noise vibration V70-XC70 2001

posted by  someone claiming to be Steve P. on  Mon Dec 3 18:07 CST 2001 [RELATED]

Hi there,

I think I know where your noise is coming from - I have the exact same issue. Under the engine compartment is a plastic "belly-pan" cover that protects the engine and also has some integrated NACA ducts for cooling. This cover is secured with approx. 5 or 6 bolts to the frame of the car. Everytime I go in for an oil change I have to crawl under the car to make sure that they fully tightened the bolts. While I was tightening the last time I decided to tap on it to see if it was loose and long and behold I heard that annoying vibrating sound. There are a few "touch-points" that cause the cover to vibrate when the engine is at very low rpm or under a lot of load under low rpm. So what I did to fix it was simply add some aluminum spacers around the outer edges between the cover and the frame - guess what the vibration is now gone....

I hope this helps....

Steve
