- Often visible without removing major components
- May be stamped into the metal or on a metal plate attached with rivets or screws
How to locate:
1. Open the hood and look towards the rear of the engine block near the transmission.
2. Examine the area around the bell housing, where the engine mates with the transmission.
3. Look for a metal pad or flat surface with stamped characters.
Tip: Use a flashlight and mirror if necessary to see into tight spots.
Serial Number Plate on the Valve Cover
In some models, the serial number is affixed to a metal or plastic plate on the valve cover.
Details:
- Usually a small metal tag riveted or bolted onto the valve cover
- Contains a barcode, serial number, and sometimes additional engine info
Procedure:
- Locate the valve cover at the top of the engine
