Heavy Equipment Cooling Specialist
Semi truck oil coolers from Radiator Supply House cover a wide range of heavy-duty applications, including Freightliner, Kenworth, Peterbilt, and International truck models. These OEM-compatible engine and transmission oil coolers help regulate operating temperatures, extend engine life, and prevent costly overheating during long-haul and fleet operations.
An oil cooler regulates engine or transmission oil temperature by dissipating excess heat generated during operation. In semi trucks, this is critical for preventing oil breakdown, reducing engine wear, and maintaining safe operating temperatures during long-haul runs. Without a functioning oil cooler, elevated oil temps can lead to engine damage, transmission failure, and costly unplanned downtime.
