After oil change on 2010 mercury mariner I hear a whistle when i accellerate


Did you remove any plastic/metal splash shields under there to get to the oil plug/filter?
Make sure you put those back in correctly as they could catch air and make noise if put in wrong.

Other than that, I can't think of anything oil change related that would cause a whisteling sound.

It sounds that the horizontal output section circuit to your TV is to be checked. It is really a skilled work. Contact any service technician.

Whistling on startup - Madza 121


Sounds like a fan belt problem if its burning that bad for that long it's likely to need to be replaced by now. Tightened the same day it started may have saved the belt

High pitched whistling on startup - madza121


The symptoms sound like a loose fan belt to me. That is normally described as a screech instead of a whistle but everything else matches.

This should not be hard to fix your self. Also a mechanic should be able to do it in 10 minutes including chatting to you.

If it is a fan belt your mechanic will know the sound 4 streets away too :)

For a short term fix and to prove if this really is the problem you can get your self something called "Belt Grip" It is in a spray on can. Follow the instructions on the can and if it fixed the problem you have the cause. Either get someone else to tighten your belt up or figure out how it's done. Basicaly you just loosen an adjusting bolt normally on the alternator and slide it out a little bit on it's track then tighten it up again.

Hope this helps

My 2002 Kia Sedona started making a whistling sound when driving or turning, if I keep the wheel just right it doesn't then it got louder and louder and now there's a grinding sound and feel, which is made...


I have a similar problem with my kia sedona 2003. The kia dealer told me to have the disc pads replaced. I brought it to a brake pads bonding shop cause its cheaper to replace there. But the thinnest pad are still half thick. The real problem was on the back plate, it's touching on the brake disc making the sound and scratching it. Just push the back plate away from the disc to solve the problem. If I have known this I could have used those disc pads for a few more months.

Noise in trans or in primary chain


It sounds like the primary drive chain is loose. The way I adjust mine is to take off the upper left inspection cover, start the bike and slowly tighten the adjuster until it starts to wine, then back off until it stops. Rev it slowly and listen for a wine. No wine good to go.

Occasional 'whistling/whining' from back of TV


I wonder if there is enough air circulating around your equipment?? My DVD recorder makes a sound unless I open the doors on the cabinet that contains all of my equipment. The cable company says it is a fan to cool down the units.
