What happens when a 53 block cracks?
53 Block Casting Identification & Information The cracks can grow several inches in length and result in coolant loss. If the problem goes unnoticed long enough, overheating from coolant loss may occur.
Where are the cracks on the 53 Block?
Cracks commonly develop on the passenger side of the 53″ blocks, right below the freeze plugs. Automatic transmission owners may have difficulty viewing cracks because they often occur directly beneath the automatic transmission heat exchanger. Cummins “53” blocks can be identified by a “53” casting number located on the side of the block.
What causes a ISB 53 block to crack?
Simply, the worry is that the block will crack. These blocks have thinner water jacket walls than other blocks so with coolant cavitation, corrosion, coolant pressure in the block, and torque, they may crack, spilling your coolant.
What causes the 53 block of coolant to crack?
Due to the lack of material in this area, the 53 blocks are susceptible to cracking — thereby leaking coolant — when the engine is exposed to heavy towing, high torque levels, elevated coolant pressure and instances of overheating. Cracking commonly occurs on the passenger side, just below the freeze plugs.
What causes cracks in cast iron engine blocks?
The problem for the 5.9 #53 Cummins engine blocks occurs during the warm up period and not during high load periods. Heat causes thermal expansion. Thermal expansion can develop enough pressure to cause cracks in cast iron.
