Problem
In some applications, dust or debris can cause air side plugging of the folded core modules in certain IT18, IT18B, IT28, IT28B Toolcarriers; 916, 926/926E, G926, 936/936E, and G936 Loaders. If this plugging occurs frequently, it will result in decreased maintenance intervals and increased downtime. The Affected Product equipped with a folded core radiator or an earlier version of the multiple row module radiator can be updated to the current multiple row module radiator design. The current multiple row module radiator design has increased strength and rigidity to prevent the radiator cracking due to machine vibration.
