Browse by component type and part number to narrow your search and identify parts listed for your specific engine application.

C15 Fuel System and Engine Components

The collection includes fuel injectors, fuel pumps, a fuel primer pump, a fuel priming pump base assembly, a throttle position sensor, a camshaft, and an overhaul gasket set. Verified examples include fuel injector 253-0614, fuel transfer pump 394-1245 / 20R-1523, and camshaft 10R3323 / 2500740 / 3327299.

Turbochargers, Cooling, and Supporting Components

For air intake and cooling-related repairs, listings include turbochargers, turbocharger intake elbow 7W3144, water pump 1615719 / 161-5719, thermostat 247-7133, fuel cooler core 129-5429, oil cooler 391-6411, radiators, and A/C condensers.

These parts serve different engine and equipment applications; a shared C15 designation alone does not establish compatibility. 

Find the Correct Caterpillar C15 Replacement Part

Before ordering, compare the part number on your existing component with the product listing. Confirm the engine model and serial number where applicable, along with the equipment application and any relevant configuration details. For fuel injectors, turbochargers, and engine rebuild components, review the product description carefully to verify the component type, condition, and included parts.

Frequently Asked Questions

How can I make sure a replacement part fits my Caterpillar C15 engine?

We recommend starting with your engine serial number and the part number on the original component. Compare those details with the Caterpillar C15 replacement part listing and confirm the engine application. Different C15 configurations may require different parts, even when the components appear similar. If the listing does not provide enough information, send us your engine details and original part number for review.

What should I check before ordering a C15 engine rebuild kit?

Check your engine identification, the kit's component list, and any specified dimensions or machining requirements. Rebuild kits can differ in their included pistons, liners, bearings, gaskets, and seals. We recommend comparing the kit specifications with your engine's service information before ordering, particularly if your engine has been rebuilt or modified previously.

Are all Caterpillar C15 fuel injectors interchangeable?

No. Our Caterpillar C15-related collection include injectors with different reference numbers and product conditions. You should not choose an injector based only on the C15 engine designation. Compare the original injector part number, engine identification, and stated application. Also check whether the product is supplied individually or as a multi-piece set.

What if the replacement C15 part looks different from the one I removed?

Do not install it until the difference has been checked. Compare the reference numbers, mounting or connection details, and any relevant specifications. Some replacement components may have different appearances, but that does not establish compatibility. If you cannot confirm the match, provide photographs and identification details before proceeding.

What should I do if my C15 engine still has the same problem after replacing a part?

First, verify that the replacement matches your engine application and that installation followed the applicable service instructions. Continued symptoms may indicate another fault in the fuel, cooling, lubrication, electrical, or air intake system. We recommend following the appropriate Caterpillar diagnostic procedures rather than replacing additional components without identifying the cause.
