You know that uneasy feeling you get when your car starts making a weird noise? You don't know where it's coming from and, whatever it is, you certainly won't know how to fix it.
Your best-case scenario is that you get to where you're going before anything goes wrong. Then, you'll take it to a mechanic who'll charge you $50 just to look at it. If there's a problem, even a minor one like a dying battery, it'll end up costing you a couple of hundred dollars for parts and labor, if not a lot more.
Fortunately there are alternatives. You can check YouTube and other sites for how-to videos, for everything from changing a tire to changing your timing belt. Who knows, maybe you'll be able to fix that noise on your own.
One heads-up, though: Those instructional videos can be intimidating, especially when the instructor is covered in grease and lifting parts that weigh 15 pounds or more. There is an easier way to find out what's going on with your car, and it's a lot of fun, too.
It's a site called How A Car Works, and it highlights each part of a car with 800 color illustrations. It explains what each part does, what can go wrong with it, and how to fix it.
