The second potentially deadly flaw occurs in '99 to '02 5.9L Cummins 24-valve engines. It's known as the 53 block problem, because these engine blocks have the number 53 cast into the side of the crankcase. After years of use, the 53 blocks tend to crack until coolant starts to pour out the side of the block.
Keeping this in consideration, what's wrong with a 53 block Cummins?
The # 53 block casting has inherently thin water jacket walls that are susceptible to cracking. Frequent and/or heavy towing, failing to let an engine properly warm after a cold start, and engine overheating can contribute to the development and propagation of cracks in the water jackets of these engine blocks.
Also Know, do all 53 blocks crack? Yes all of the 53 block cracks are occurring on the right rear of the motor(except for a few on the left rear). But who knows if yours will crack. Mine was cracked for 10,000 miles that I know of with a very small amount of coolant loss.
In this manner, how do I know if my Cummins is a 53 block?
Cummins "53" blocks can be identified by a "53" casting number located on the side of the block. The casting number is commonly seen on the passenger side, below the injection pump, although some #53 blocks have the casting number located on the driver side near the front of the engine.
