C15 Acert, C15 Black Series Water Pumps, 10R8660, Caterpillar, New

Caterpillar C15 and C15 Acert Black Series Water Pump FAQ, Part Number 10R8660

What engines does the Black Series Water Pump (10R8660) fit?

This water pump is designed specifically for the Caterpillar C15 and C15 Acert diesel engines. It cross-references a wide range of OEM and aftermarket part numbers including 10R2776, 10R3326, 10R6225, 10R8662, 2243236, 2243237, 2243238, 2243239, 3145155, 3362213, 2282322, and many others. Because diesel engine parts are engine-specific, HHP recommends confirming your engine serial number before ordering. If you need fitment assistance, our ASE-certified technicians are available at 844.215.3406.

What makes the Black Series Water Pump better than a standard replacement?

The Black Series designation reflects a higher manufacturing standard than a typical aftermarket replacement. This water pump features a new casting, which eliminates the metal fatigue that accumulates in used or remanufactured housings from repeated heat cycles and mechanical stress over time. It is manufactured in an ISO 9001:2015 certified facility using hard-wearing materials engineered for long-lasting durability, and it is guaranteed for OEM fit and function. The result is a water pump that meets or exceeds OEM performance specifications at a significantly lower price than the Caterpillar dealer equivalent.

Why does my Caterpillar C15 or C15 Acert need a new water pump?

The water pump is the core of your C15 and C15 Acert cooling system. It circulates coolant through the engine continuously to maintain safe operating temperatures under load. When the pump wears out or fails, coolant flow is compromised, leading to overheating, steam from under the hood, coolant leaks, and potentially catastrophic engine damage. Common symptoms of a failing C15 or C15 Acert water pump include engine overheating, coolant leaking near the front of the engine, a grinding or whining noise from the pump bearing, and unexplained coolant loss. Addressing a failing pump promptly protects your engine from far more expensive damage downstream.

What warranty comes with this water pump?

This Black Series Water Pump is backed by a 1-year unlimited mileage parts and labor warranty. This covers both the part itself and the labor required to replace it, which is a stronger coverage than the parts-only warranties offered by many competitors. ASE-certified technician support is also available from purchase through installation at no additional charge.

Is this water pump new or remanufactured?

This is a brand new water pump with a new casting. It is not remanufactured, reconditioned, or rebuilt from a used core. This distinction matters because remanufactured pump housings carry residual metal fatigue from prior heat cycles and mechanical stress, which can compromise service life. With this Black Series pump, you are installing a component with no prior wear history, giving your C15 or C15 Acert the best possible foundation for long-term cooling system reliability.

Is there a core charge on this water pump?

No. Because this is a completely new unit, there is no core charge. You pay for the pump, it ships, and there is nothing to return. This simplifies the purchase and eliminates the core deposit tracking that comes with remanufactured parts.

What are the OEM cross-reference part numbers for this water pump?

This water pump replaces a broad range of OEM and aftermarket part numbers including 10R2776, 10R3326, 10R6225, 10R8660, 10R8662, 2243236, 2243237, 2243238, 2243239, 2282322, 2463132, 2463434, 2533438, 2640536, 2764755, 2807373, 2807374, 3145155, 3362213, 3528589, 381809, 6031668, 6V7703, AK3145155, FP3362213, M3362213, RW1017X, and US6342, among others. Use these numbers to confirm you are ordering the correct replacement for your specific C15 or C15 Acert application.

How is this water pump different from the Black Series Water Pump for the 3406E (part number 381802)?

Both are Black Series water pumps built to the same ISO 9001:2015 certified manufacturing standard with new castings and no core charge. The key difference is engine fitment and warranty coverage. The 381802 is engineered for the Caterpillar 3406E and carries a 2-year unlimited mileage parts and labor warranty, while the 10R8660 is built specifically for the C15 and C15 Acert and carries a 1-year unlimited mileage parts and labor warranty. The internal and external dimensions, impeller design, and mounting configuration differ between the two engines, so the pumps must not be interchanged.

What are the signs that my C15 or C15 Acert water pump is failing?

The most common warning signs of a failing water pump on a Caterpillar C15 or C15 Acert include engine overheating, coolant leaking from the weep hole or pump housing at the front of the engine, a grinding or rumbling noise from the pump bearing, steam rising from under the hood, and unexplained coolant loss between service intervals. If your C15 or C15 Acert is running hotter than normal or losing coolant without a visible external leak, inspect the water pump immediately. Ignoring early warning signs can lead to head gasket failure, warped cylinder heads, and severe internal engine damage.
