Casting Number Basics
Finding the casting numbers on a Jeep 6 cylinder engine block helps identify the engine model and its production date. These numbers are usually raised or stamped on the metal surface of the block. Knowing the exact location makes it easier to read and verify the engine details. Below are the main places where you can find these casting numbers.
Rear Of The Engine Block
The rear of the engine block is a common place for casting numbers. Look just below the cylinder head at the back side. The numbers here are often raised and easy to spot. This location is ideal because it stays clean and visible even after years of use.
Passenger Side Positions
On the passenger side of the engine block, casting numbers may appear near the oil filter or towards the front. These numbers are usually large and raised from the metal. Checking this side helps if the rear location is hard to reach or covered by other parts.
Other Common Locations
Besides the rear and passenger side, casting numbers can also be found on the top deck or the sides of the engine block. Sometimes, they appear near the water pump or below the cylinder head. Inspect these areas carefully, especially if the usual spots have dirt or rust.

Avoid reading numbers covered in dirt or rust without cleaning the block first. Never rely on blurry photos or faded markings alone. Check the exact location of the casting number, usually on the rear or side of the block. Mistaking the location leads to incorrect identification.
Verifying With Multiple Sources
Check casting numbers against official Jeep manuals or trusted Jeep forums. Mopar’s website provides factory build details using the casting number and VIN.
