Mack E7 Engine Oil Cooler

An engine oil cooler transfers excess heat from circulating engine oil to coolant or ambient air, keeping oil temperatures within a safe operating range. This prevents oil breakdown, reduces friction-related wear on internal components, and helps the Mack E7 maintain consistent performance during heavy-duty, high-load, and extended-duty-cycle operation.

Yes, our oil coolers are designed as OEM-equivalent, direct-fit replacements, matching original mounting points, port configurations, and thermal performance specifications. This allows for straightforward installation without modification, helping minimize downtime while restoring factory-level cooling performance to your Mack E7 engine.

Mack E7 engines are commonly found in heavy-duty commercial trucks, buses, motorhomes, and vocational vehicles used in construction, waste hauling, and fleet operations. Our broader oil cooler catalog also supports construction equipment, agricultural machinery, and industrial air compressors requiring reliable oil temperature management.

Common warning signs include rising oil temperatures, oil in the coolant (or vice versa), visible leaks around the cooler housing, reduced engine performance, or frequent overheating. If you notice any of these symptoms, inspect the cooler for corrosion, cracked cores, or clogged passages and replace it promptly to prevent engine damage.

Yes, we stock combo units that integrate the radiator and oil cooler into a single assembly, simplifying installation and saving space on equipment such as excavators, compactors, and air compressors. These units range from approximately $1,361 to $9,995 depending on manufacturer and model compatibility.

Oil coolers in our catalog range from approximately $1,297 to $22,591 depending on the equipment application, manufacturer, and cooler size. Pricing varies for heavy construction machinery, agricultural equipment, trucks, and industrial compressors, so contact our team for an exact quote based on your specific model.
