ChiltonDIY Tips for Taking on a Car Repair
Before you start working on your car or truck here are some tips to guide you through the process.
First, identify the job at hand. Are you trying to fix something (stop a leak, quiet a noise, start the vehicle) or perform routine maintenance? Do you have the time, tools and skills needed to do this work? If you have the time but aren’t sure whether you have the skills, are you willing to acquire the skills on the job with some help from a friend and/or with a repair manual, such as Chilton? If you are missing some of the tools needed, can you buy or borrow them in time to finish the work?
Okay, if you are willing to learn the skills and acquire the tools to complete the job in your spare time, let’s begin. Write down any symptoms with details about when they occur. Note the vehicle mileage so you can find the right maintenance schedule to use.
Whether you are fixing a problem or performing maintenance, check the owner’s manual and a repair manual resource (such as ChiltonDIY, available online) for specifications, procedures and illustrations. These will help you determine what needs attention and provide cautions and warnings to heed.
Before getting parts, write down the Vehicle Identification Number (VIN). You can see it from outside the vehicle in the lower corner of the driver’s side windshield. This number is very important when ordering parts and finding the correct procedures and specifications. To avoid mistakes when writing it down, you may want to take a picture of it.

The vehicle identification number (VIN) is usually visible from outside of the driver's side window.
Open the driver’s door and record the certification information that is found on the door or pillar, such as the year and month of the vehicle’s manufacture because you may need the exact month when ordering parts.

Now you have the basic information to isolate issues and order parts.
After reading the repair procedure in ChiltonDIY, check what tools are needed to perform the job. If you need additional tools, make sure you have the time to buy or borrow quality tools, because they will make the job so much easier than if you use inadequate tools. Here is some more information on basic hand tools.
If you lack much experience, ask other DIYers and research on the internet which parts are best to use for your job, based on other people’s experiences. Check the price of the OEM (original equipment manufacturer) part, and then check to see if there is a quality aftermarket part that others have used successfully. Buyers beware! How does the old saying go? “You get what you pay for!” Save all your receipts and record all of your repairs, especially if your vehicle is under warranty.
After finishing the job, congratulate yourself on saving money while gaining experience and learning additional skills. If you acquired some new information and tools in the process, they might have already paid for themselves with this one job; or certainly they will with a few more. Your friends and neighbors might need your help fixing their cars soon. Now you can show them how!
