Alright.
If you spend 15 mins reading through this forum and use the search button located conveniently at the top of the screen for ease of use, you'll answer your questions. In fact, you'll answer questions that you'll have after you've found the answers to your first questions.
We're here to help, but take some initiative and learn. It gets very tiring answering the same questions over and over.
And
www.howstuffworks.com is an awesome site if you're just getting started learning about cars.
Good luck dude.
