  • Tip of the Week (1) for October 4-10, 2015

    For the first Tip, let's start at the beginning. It's a good idea to know as much about your truck as possible. I created a notebook and in that book is everything that pertains to my truck. I started off with writing down the information on the ID Plate located inside the driver's side door jamb. Next, based on the year of the truck, I went to the GM Heritage site and downloaded the PDF File that corresponds to my year of truck. Get yours here:

    Included in this package is a decipher page that will help you understand everything that ID Plate says. The bonus is, there is a lot more than that in this package. Next, I wrote down the number on the passenger side of the engine just to the left of the road draft tube and just under and to the right of the Distributor. This usually 7 digit number is the Engine Casting Number and you can find out what years your engine was made here:

    Once you have the years your engine was made, get the numbers off the flat part of the Distributor mounting area to narrow it down even further. This information is important when it comes to purchasing engine parts or learning about nuances. You can identify your engine down to what day it was made by following the instruction here:

    Put all of this information in your notebook so you have it handy. After you have done this, there is one more identification item that is important. You need to determine the number of teeth on your flywheel's Ring Gear. This is important for when you need to purchase a new starter. A 4 tooth per inch, 139 tooth flywheel equals a 6 volt starter, while a 5 teeth per inch, 168 tooth ring equals a 12 volt starter. You can read all about it here:

    The idea of the Tip of the Week is not only to educate and learn, but to get you all to post your thoughts!
