With how much you are trying to learn from such a basic starting point you should really try to find somebody you know to help you out. Most of the stuff you are asking is not specific to a Bronco, Ford or any vehicle so anybody with any mechanical experience should be able to help you. If you don't know anybody (even somebody in your family you could call to ask?) you could put up an ad on craigslist or something saying you'd like to pay somebody a little bit to come answer some questions. You might not get a seasoned mechanic because they are going to be able to make more money fixing stuff than teaching people but you'll probably get somebody that does their own work and can answer the simple stuff. Heck, you might even find a wrenching buddy. Anyhow, doing so would save everyone a lot of time most of all yourself. You just spent all day getting answers to things somebody could've shown you in about half an hour. Just a suggestion. You also might post a picture of the cover of your manual cause I'm kind of wondering if you bought the wrong book. None of mine have any diesel info in them but that could be different for the newer models. By the way, it's worth looking into the factory manual and the Haynes manual as well as the Chiltons you have. Each one will give you a little bit different of a view in the pictures and the writing so it helps to read all of them for whatever job you are doing then pick the most complete one for that given job to follow along with.
