car noises
Saturday, May 25th, 2013 11:39 amMy car was making an odd noise this last month, which it turns out was the alternator going bad. Normally, the engine is a low-pitched rumble. This was a higher pitched sort of whiny noise on top of the normal noise, and it increased in pitch as the car drove faster. It wasn't loud enough for me to be sure that something was wrong, but it was different enough to make me wonder. The sound was like the noise a small electric motor can make; sort of like a sound-effect in a video game.
The noise started after we had a bunch of other work done on the car, including new spark plugs, getting the power steering pump and oil pan gasket replaced (due to fluid leaks), and getting the A/C compressor replaced (as the A/C hasn't worked in forever). (There must still be a freon leak somewhere else, as it all leaked out again, and smelled nasty while it was doing so.)
So I was thinking, maybe the car simply sounds different due to having new parts.
This week, one day the battery light came on for just a few seconds and went out again, and the next day it came on and stayed on. So I had the car checked, and they said the alternator was bad. After getting it replaced, the odd noise is gone, and my car sounds like normal again. Yay.
From what I've read, power steering fluid or other fluids leaking onto the alternator can cause it to go bad. Yet, my car doesn't seem to have any hoses by the alternator that could drip onto it. Maybe it was just coincidence.
...Oooh. While going through my notes now, it turns out that I already had my alternator replaced 2 years ago, along with my belt and battery... so it wasn't a 17 year old alternator after all, like I was thinking! Hmmm.
Oh well. Hopefully it's all good now. I like my little car, and now that I've decided to keep it, I want it to keep running a long time.
