I did a search and couldn't find anything on this, so I thought I would start a thread to help anyone who is thinking of beginning to do some basic maintenance /repairs on their cars at home. The information here will be VERY BASIC and in simple language so as to not confuse people who have never done this sort of thing before, or who have done very little of it. If you want to chime in and offer other suggestions, please do so. Some of the things I am going to suggest might seem odd to people who are professional mechanics or serious hobbyists, but this thread is aimed at the guy or girl who is not as familiar with this stuff as some of us.
First the basics:
1) Cars today can be held together with either METRIC or SAE (inch increment) sized bolts and nuts. Some cars have both types of fasteners on them, so you have to sometimes try fitting a couple of different sockets or wrenches on to know what one fits the tightest.
2) You can borrow some tools from places like Advance Auto or Autozone, you simply pay a deposit and when you return it you get your money back. I do this occasionally, even though I have a shop full of almost every tool that exists, because there are some tools you will only need once in your lifetime, and it doesn't make sense to own it.
3) Autozone and Advance Auto will also provide a free scan of your car if it is showing a warning light on the dash. It will narrow down what area is causing the code to be thrown and then you will know where to begin.
4) The internet is a HUGE resource for information. Whenever I have something going on with a car, and am not familiar with that area, I turn to the internet. You can also go on YouTube and find a video or two on every repair you are going to make. I use YouTube for everything I am doing , from fixing stuff to cooking dinner.
5) Know your limitations. I build cars, but sometimes I take my family car to a local shop because I am an old school hot rodder and things like fuel injection, computers, and sensors are over my head. On some repairs, you really can't do anything without very expensive diagnostic equipment, not something we at home generally have.
6) A Chlltons or similar shop manual for your specific car can be a great help, and are available at most auto parts stores. They are not nearly as good as the expensive shop manuals put out by GM, Ford, etc for their own cars, but for about $20 or so, they will get you through most jobs.
Tools to own:
You DO NOT NEED PROFESSIONAL GRADE TOOLS to do most home repairs. I have a lot of expensive SnapOn, MAC, MATCO, etc tools in my shop, but the average home tinkerer doesn't need those for the occasional jobs they will be doing. Sears sells some very nice tool sets that come in a plastic case, and they will do most anything you need to do. Other places are Lowes (their Kolbalt tools are actually not bad at all and reasonable) and even Harbor Freight.
Ok, let's talk about Harbor Freight. A lot of car nuts scoff at Harbor Freight and say they sell Chinese crap...........and I will admit SOME of their stuff is junk, but not ALL OF IT. You have to pick and choose. For example, I have a $ 300 Craftsman floor jack that failed after one year and Sears would not stand behind it. However, I have two Harbor Freight floor jacks that were under $100 each, and they work great and have lasted for years. For a lot of tools and a lot of hobbyists, HF is a great source for tools.
What kind of tools do I need?
A good, basic tools set will contain socket sets in 1/4 inch drive and 3/8 inch drive sizes, and will include a complete assortment of sockets in both metric and sae sizes. It will also have extensions to enable you to reach into tight spots, and a U joint to let the socket angle to reach into strange spots. Socket sets also come in 1/2 inch drive sizes, and larger, but, for most basic repairs, a 3/8 set will do the job.
It will also contain a complete set of metric and sae combination wrenches (open end on one side and box end on the other), a couple of sizes of flat bladed screw drivers and a couple of sizes of Phillips screw drivers.
Those would be the most basic needs. Beyond that, you should have a Cresent (adjustable wrench), a good pair of Vice Grip brand vice grips ( most knock offs suck) and some various pliers, like needle nose, and side cuts (to cut wiring and things like that). Also, a medium size ball peen hammer (don't use a claw hammer to work on a car, people will know you are a beginner !
) Other nice tools to have would be a set of Allen wrenches (hex head),
Something I have come to love is the headlight I bought......it is one of those LED flashlights that has a strap to hold it on your head (like a sweat band) and you can aim it at the work you are doing without holding a light. The first time I saw my Son with his I laughed, until I tried it and it sure makes things a lot easier.
Safety:
This is a biggie, and something not to be taken lightly. If you are going to be doing ANY work under or near a jacked up car, you need to block the car up correctly. A set of heavy duty jack stands MUST be placed under the frame to make it safe enough to climb under there.......even to change the oil. I have a bunch of them, mostly from Harbor Freight, and they are fine, but I also keep the floor jack under the car at the same time just to be safe. MAKE SURE THE CAR IS ON A LEVEL, HARD SURFACE SO THE JACK STANDS DON'T KICK OUT OR FALL ! Put the car in park and also apply the emergency brake. Before you climb under, grab the car and try shaking it to make sure it is securely supported. Have someone else near by in case the worst should happen and you need help.
It is also a good idea to have a fire extinquisher nearby if you are doing a lot of jobs.........one has save me more than once !
Where to get started:
For the purposes of this discussion, we are assuming you know little or nothing at all about fixing your own car, so don't jump right in and do a brake job. Start small. Learn to check the fluid levels.....then maybe move up to changing your own oil. You can also do minor tune ups (cars today are pretty much limited to just changing spark plugs, and even those last a very long time now). Change burned out light bulbs, and do other repairs like that to give you more confidence to move onto other tasks.
Why even do this at all ?
Because it can be fun and very satisfying. There is something about dragging out your toolbox on a Saturday morning and the sense of accomplishment when it actually works when you are done. Is it for everyone ? Nope, and some people are just better off taking their car to a professional. But you just might learn something and save a few bucks along the way.
I hope some others join in with suggestions and questions about this subject.
