The D 89103 radiator is designed for the engine cooling system of CASE 580 C backhoe loader.
Its primary function is to dissipate engine heat and maintain a stable operating temperature during daily and heavy-duty machine operation.
This radiator is directly interchangeable with part number D77843 and can be installed without any modification.
It is installed at the front cooling / fan side of the engine compartment.
The radiator is manufactured with:
-
high-density cooling fins
-
reinforced core structure
-
durable aluminium and metal construction
to ensure:
-
efficient heat dissipation
-
stable coolant circulation
-
reliable cooling performance under continuous working conditions
This radiator is suitable for replacement, overhaul and cooling system restoration for CASE 580 C machines.
Troubleshooting – When should this radiator be replaced?
Replacement or inspection is recommended when the following conditions occur:
-
engine temperature rises abnormally
-
frequent overheating during operation
-
coolant level drops without visible hose leakage
-
coolant stains or wet marks found on the radiator core or tank
-
radiator fins are severely blocked, bent or damaged
A faulty radiator can reduce cooling efficiency and may lead to engine overheating and internal engine damage.
