PROBLEM

In some high load factor applications, high ambient temperature conditions may cause the engine coolant to overheat on certain 320C and 320C L Excavators that are equipped with EPA Tier-II emission engines. The machine controller group needs to be re-flashed with new software. The oil cooler/radiator compartment service door may also need to be replaced with a perforated 2084108/">208-4108 Door Group or 192-6582 Door Group, if the machine is not already equipped with these doors. The 2084108/">208-4108 Door Group and 192-6582 Door Group, allows more airflow through the radiator and hydraulic oil cooler.
