Tacoma Posted August 13, 2007 Share Posted August 13, 2007 Lately I'm getting a subtle high pitch "Wherring" sound in my engine compartment. Under the hood it sounds like it is coming from the timing belt area. It increases and decreases when I step on the gas feed and /or let up on it.It dosn't seem to effect the engine operation,Electrical or anything else that I can determine.Any suggestions as to Link to comment Share on other sites More sharing options...
Guest MauiWowee Posted August 13, 2007 Share Posted August 13, 2007 When the alternator in my van did that, I had one day before it was fried. Carefully, hold a LONG screwdriver to your ear, then the alternator. (unless you have a stethescope). Link to comment Share on other sites More sharing options...
Vincent Vega Posted August 14, 2007 Share Posted August 14, 2007 Anything that rotates in that area can be the problem. Alternator, ps pump, water pump, AC compressor, or tensioner. The stethoscope/screwdriver is a great idea. Be careful. First thing I would do is disconnect the serpentine belt and run it for a few minutes. That could eliminate all of the above. Past that use the method above to see if any of the components are the source. Link to comment Share on other sites More sharing options...
Tacoma Posted August 14, 2007 Author Share Posted August 14, 2007 Thanx Guy'sI disconnected the serpentine belt, ran the engine for about 15 seconds and did not get the high pitch sound. Is there any way that I could have the belt too tight and is there an adjustment for the tensioner (or other things on the belt such as PS,AC etc:) on the belt. Thanx Link to comment Share on other sites More sharing options...
Guest MauiWowee Posted August 14, 2007 Share Posted August 14, 2007 What you have done is to narrow your search down to the things listed in Vincent Vega's post. Use my method (I can't stress enough how dangerous this is) to find exactly which one of the above it is.Good luck Link to comment Share on other sites More sharing options...
Roadster90 Posted August 14, 2007 Share Posted August 14, 2007 I bought an actually 1/2 way decent automotive stethascope (sp) at Harbor Freight for $1.99 to replace a real one a nurse gave me...It has an attachment, and was almost quality made even if it was manufactured in china.....think it is about $4.00 regular price.I am on the coupon mailing list for Harbor Freight...some far out bargins every week over and above their regular sales paper....HF is now my favorite "Toy Store" If you are not a professional technician or a showman, HF products that you may use a couple of times are just fine.

Tacoma Posted August 14, 2007 Author Share Posted August 14, 2007 Thanks again guys. I put the belt back on and the whine has receded grately. Don't know what it was but the alternator seems to be charging fine. Took it for a test drive. (A little cowel shake at 110 mph but thata all) Only kidding. Seems OK so far. Wonder if the belt may have been off track a bit.My daughter is an RN at St Joseph hospital here, She is bringing her stethoscope over tommorow. Hopefully I can narrow it down more then.
