About Engine oil cooler

Explore replacement engine oil coolers and related components for diesel engines, construction equipment, agricultural machinery, trucks, and selected passenger vehicles at Fab Heavy Parts. This collection includes engine oil cooler assemblies, oil cooler cores, covers, and other application-specific replacement components.

Engine Oil Coolers for Diesel Engines and Heavy Equipment

An engine oil cooler helps manage engine oil temperature by transferring heat away from the oil. Different engines use different cooler designs, mounting arrangements, and connections, so selecting the correct replacement is important.

Our collection includes oil coolers listed for a variety of applications, including:

  • Caterpillar: C15, C18, 3306, and selected 3406-series engines.

  • Deutz: F3L2011, F4L2011, BF4M1013, and selected TCD-series engines.

  • Isuzu: 4BG1, 4BD1, and 6HK1 engines, including selected Hitachi excavator applications.

  • Yanmar: 4TNV82, 4TNV84, 4TNV88, 4TNV94, and 4TNV98 engines.

  • Kubota: V3307 engine applications, including selected compact excavators and loaders.

  • Cummins: Selected 6B5.9, ISL9, and QSL9 applications.

These examples reflect individual product listings. Confirm the exact part number and engine configuration before choosing a replacement.

Oil Cooler Assemblies, Cores, and Covers

Not every product in this collection is a complete engine oil cooler assembly. Depending on the application, you may find an oil cooler core, a complete cooler unit, a side cover, or a related component.

An oil cooler core and a complete assembly serve different replacement needs. Before ordering, review the product title, photos, and included components to confirm whether you are replacing the entire unit or a specific part.

Choosing the Correct Replacement Engine Oil Cooler

Start with the engine manufacturer, exact engine model, and original cooler part number. Compare the replacement listing with the existing component's mounting points, connection arrangement, dimensions, and included parts.

Similar engines may use different cooler configurations. Do not assume that products with similar appearances or overlapping model descriptions are interchangeable.

Before installation, inspect the associated oil and coolant passages, seals, and mounting surfaces as required by the manufacturer's service instructions. If you are unsure which replacement is needed, gather your engine identification information and photos of the original component for further review.

Frequently Asked Questions

How do I know which engine oil cooler fits my equipment?

Start by checking your engine manufacturer, exact engine model, and the part number on your original oil cooler. Compare those details with the replacement engine oil cooler listing, including the mounting arrangement and oil or coolant connections. Equipment models alone may not provide enough information to confirm compatibility, especially when different engine configurations are available.

What's the difference between an oil cooler core and a complete oil cooler assembly?

An oil cooler core is the heat-exchanging component, while a complete assembly may include additional housing or mounting components, depending on the design. Our collection includes both types, along with selected covers and related parts. Check the product description and photos carefully to confirm what is included before ordering.

Can you help me find a replacement oil cooler if I only have the old part number?

You can use the original part number to search our collection or provide it when requesting compatibility assistance. If the number is incomplete or difficult to read, include your engine model, equipment details, and clear photos of the existing cooler. These details can help identify potential replacements, but the final fitment still needs to be confirmed.

Do I need to replace the gaskets or seals when installing a new engine oil cooler?

The sealing requirements depend on your engine and oil cooler design. Some installations require replacement gaskets, O-rings, or other sealing components, but you should not assume they are included with every cooler. Check the engine oil cooler listing and follow the engine manufacturer's service instructions for the correct parts and installation requirements.

What should I check if I still notice oil and coolant mixing after replacing the oil cooler?

Stop operating the engine until the cause has been identified. Oil and coolant contamination can result from more than one component or sealing issue. A qualified technician should inspect the cooling and lubrication systems, verify the installation, and follow the engine manufacturer's diagnostic procedures. Replacing the oil cooler alone does not guarantee that the underlying problem has been resolved.
