Stellar Industries 106185 Oil Cooler for 30P and 40P Air Compressors

If you’re unsure whether this part is compatible with your truck or equipment, please contact us to confirm fitment before purchasing.

The Stellar Industries 106185 Oil Cooler is designed for compatible Stellar 30P and 40P hydraulic air compressors. This air-to-oil heat exchanger removes excess heat from the circulating compressor oil to help maintain the correct operating temperature under demanding service conditions.

Proper oil cooling preserves lubrication performance and protects the compressor’s seals, bearings, and internal components from heat-related damage. Part 106185 is also the specified service replacement when a 30P application references the earlier C1129 cooler.

What This Part Is Used For

The Stellar 106185 cooler transfers heat from the compressor oil into the surrounding airflow. Maintaining a controlled oil temperature helps prevent overheating, premature lubricant breakdown, reduced compressor performance, and automatic high-temperature shutdowns.

Common Reasons For Replacement

Compressor oil temperature is excessively high
Oil leaks from the cooler core
Cooler fins are bent, clogged, or damaged
Cooling performance has decreased
Oil passages are contaminated or restricted
Connection ports or fittings are damaged
Cooler core is cracked or corroded
Assembly is damaged by vibration or impact
Compressor repeatedly shuts down from overheating
