EGR, Oil & Water Cooling Components for Heavy-Duty Diesel Engines

Cooling components play a critical role in maintaining stable operating temperatures, protecting engine internals, and ensuring long-term durability in heavy-duty diesel engines. This category offers an extensive range of EGR coolers, oil pumps, oil pans, dipsticks, oil filter housings, water transfer tubes, cooling plates, EGR manifolds, filler necks, engine oil coolers, and water pump-related components for engines such as Cummins ISB, ISF, ISL, ISX; Detroit Diesel DD13, DD15, Series 60; Volvo D12 & D13; John Deere 6068; Caterpillar C13; International/Navistar MaxxForce and many additional commercial powertrain platforms.

Why cooling components are essential for engine reliability

Efficient EGR, oil, and water cooling systems help regulate temperature, reduce thermal stress, prevent component warping, and maintain ideal combustion conditions under heavy load. A failing EGR cooler may cause white smoke, coolant loss, overheating, and reduced fuel efficiency. Worn oil pumps or clogged oil coolers can lead to insufficient lubrication, bearing damage, and accelerated wear. Damaged water transfer tubes, leaky oil pans, or faulty housings can result in pressure drops, coolant contamination, and long-term engine failure issues especially critical for long-haul trucking, industrial machinery, agriculture, and severe-duty work cycles.

When evaluating replacement cooling components, consider:

• correct match to OEM specifications and engine platform
• component’s role in cooling, lubrication, or exhaust recirculation
• resistance to corrosion, internal clogging, or heat cycling
• integration with related systems (EGR valves, oil pumps, coolant hoses, thermostat housings)

Engineered to maintain stable temperature and lubrication under high load

Our cooling components are built from high-strength aluminum, cast iron, and corrosion-resistant alloys designed to withstand extreme pressure and temperature fluctuations. Many parts feature reinforced coolant passages, precision-machined oil channels, and OEM-grade sealing surfaces to ensure optimal flow and long-term integrity. Whether you are replacing a Detroit Diesel DD15 EGR manifold, upgrading a Cummins ISB oil cooler, restoring an engine oil pump drive gear, or repairing a John Deere cooling housing, each component supports efficient heat dissipation and stable engine lubrication for thousands of operating hours.
