How to Identify Chevy Parts

How to Identify Chevy Parts

If you own a Chevy or simply enjoy working on cars, you most likely need to know how to identify Chevy parts. Whether you are repairing a part, replacing a part or upgrading a part, it is essential that you correctly identify the Chevy part to accurately repair or replace it. Replacing a part with an incompatible part can be detrimental to your vehicles performance. With a few guidelines, however, identifying a Chevy part is as simple as locating and decoding information on the part itself.

Instructions

Identifying a Chevy Engine

    1

    Locate the engine ID number on the engine. You may need to remove or reposition parts to view the engine ID number. The engine ID number is a seven- to eight-digit number that includes letters and numbers (for example, V0525CNR). Depending on the engine size, the location of the number varies. It is typically on the passenger side, either at the front of the block near the head, or on the block behind the distributor.

    2

    Identify the first letter of the engine ID number. This letter represents the engine assembly plant location. For example, the V in the code V0525CNR represents the Flint engine plant. You can find a listing of plant codes on websites such as Chevy-Camaro.com or by calling the parts department at your local Chevy dealer.

    3

    Locate the date the engine was manufactured. This is the series of four numbers following the plant location code in the engine ID number. For example, in the engine ID number V0525CNR, the number 05 represents the month (May), and the number 25 represents the day of the month (the 25th).

    4

    Decode the final digits of the engine ID number. These letters identify the engine type. You will need to consult an online code list or contact your local parts dealer to decode these digits.

Identifying a Chevy Transmission

    5

    Measure the length of the transmission, from the bellhousing to the tailshaft. The longest Chevy transmissions are the 700R4s, at 30 inches. The TH400 measures 28 inches. The Powerglide, 200-4R and TH350 each measures 27 inches.

    6

    Examine the shape of the transmission pan. The TH700-R4 and TH350 have the most square pans. The TH200-4R has a two-section pan. The TH400 pan has a more irregular shape. You can find pictures of additional pan shapes online.

    7

    Count the number of bolts on the transmission pan. Compare the count with pictures of transmission pans to find the right match. For example, the TH700-R4 has 16 bolts on the pan.
