If your machine is running hot, losing airflow, or showing rising coolant or hydraulic oil temperatures, the problem may be in the cooling system.
Common warning signs:
Cooling system parts support both engine and hydraulic cooling on heavy equipment. Performance depends on airflow, coolant circulation, and heat transfer — all of which are challenged in dusty environments, slow travel, or heavy-load conditions where heat builds quickly and airflow drops.
Instead of starting with a known failed part, you may begin with symptoms like overheating, poor radiator performance, weak airflow, or circulation issues. If overheating is tied to broader performance problems, inspect related engine parts.
Use this cooling system diagram as a quick reference when checking common problems such as overheating, poor radiator airflow, coolant leaks, or reduced heat transfer efficiency. It can also help identify common cooling system components, including radiators, cooling fans, water pumps, and oil coolers, before moving on to a more specific product category.
