Crystal, I have to give you props on wanting to work on your cars by yourself. Many women are intimidated by auto repair, and the more women that get under the hood and do their own work will put a dent in all those unscrupulous shops that see a girl coming in and think of her as an easy mark to make mucho bucks.
I used to work at a shop, and when I got a woman who needed her car worked on, I always showed them (if they wanted to know) exactly what was wrong, and gave them an explanation on how the problem affected their car. My boss was a real shyster (in his 80s), and encouraged me to throw on extra repairs that were unnecessary when it came to women. I couldn't do it; I'm too honest of a person.
The shop is now out of business, and good riddance in my opinion. Long before I started working for this putz, he went from 4 shops down to 1, spent time in jail for odometer and VIN tampering, and was the epitome of the sleazy used car salesman. Seriously, in 2009 he was selling a 1984 Ford F-150 2wd, 1989 Honda Accord LX, and other vehicles ALL for $3500 ($600 down, $60 a week, buy here, cry here). Most of these he bought for $15 from Adesa, whom handles vehicles donated to the American Cancer Society. I wish I could say I was making this up, but I am not...
I digress. Anyhow, bravo to you for being a woman who wants to know the workings of the engine bay, and learning how to do repairs yourself! It'* amazing how much money people could save by learning even the most basic of repairs! I am always in support of people who are willing to shatter the gender roles of society.
