What engines does the Black Series Water Pump (381807) fit?
This water pump is designed specifically for the Caterpillar C15, C16, and C18 diesel engines. Because diesel engine parts are engine-specific, HHP recommends confirming your engine serial number before ordering to ensure correct fitment. If you need fh3>What makes the Black Series Water Pump (381807) better than a standard replacement?
The Black Series designation reflects a higher manufacturing standard than a typical aftermarket water pump. This pump is manufactured in an ISO 9001:2015 certified facility using hard-wearing materials engineered for long-lasting durability under the demanding conditions of heavy-duty diesel operation. It is guaranteed for OEM fit and function, meaning it installs correctly and performs to the same standard as the original Caterpillar part, at a significantly lower price.
Why does my Caterpillar C15, C16, or C18 need a new water pump?
The water pump is the core of your engine’s cooling system. It circulates coolant continuously through the engine to prevent overheating under load. When the pump wears out or fails, coolant circulation is reduced or lost entirely, which leads to rising coolant temperatures, steam from under the hood, and potentially catastrophic engine damage. Common warning signs of a failing water pump on a C15, C16, or C18 include a rising temperature gauge, steam rising from the engine compartment, coolant leaks near the front of the engine, a grinding or whining noise from the pump bearing, and unexplained coolant loss between service intervals. Replacing a failing pump promptly is far less costly than repairing the heat-related engine damage that follows.
Is this water pump new or remanufactured?
This is a brand new Black Series water pump. It is not remanufactured, reconditioned, or rebuilt from a used core. Starting with a new pump means no residual metal fatigue from prior heat cycles or mechanical stress, giving your C15, C16, or C18 cooling system the best possible foundation for reliable long-term performance.
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 keeps the purchase simple and eliminates the core deposit tracking that comes with remanufactured parts.
What warranty comes with this water pump?
This Black Series Water Pump is backed by a 2-year unlimited mileage parts and labor warranty. This covers both the part and the labor to replace it, which is stronger coverage than the parts-only warranties common among aftermarket competitors. HHP’s ASE-certified technicians are also available to support you from purchase through installation at no additional charge.
How does this water pump compare to other Black Series water pumps HHP offers for Caterpillar engines?
HHP carries Black Series water pumps across multiple Caterpillar engine families. The 381807 is engineered specifically for the C15, C16, and C18 and carries a 2-year unlimited mileage parts and labor warranty, matching the coverage of the 3406E pump (381802) and exceeding the 1-year coverage on the C15 and C15 Acert pump (10R8660). All three are manufactured to the same ISO 9001:2015 certified standard, but the internal dimensions, impeller design, and mounting configurations differ by engine family and must not be interchanged.
What are the signs that my C15, C16, or C18 cooling system is failing?
Beyond a rising temperature gauge and steam from the hood, other signs of cooling system trouble on a C15, C16, or C18 include coolant leaking from the weep hole or pump housing at the front of the engine, a grinding or rumbling noise from the pump bearing area, sweet-smelling exhaust indicating coolant burning internally, and repeated low coolant warnings without a visible external leak. If your engine is showing any of these symptoms, inspect the water pump immediately. A failed pump left unaddressed on a high-output engine like the C16 or C18 can result in warped cylinder heads, blown head gaskets, and severe internal engine damage that costs far more to repair than a timely pump replacement.
How quickly will this water pump ship?
Orders placed by 2 PM EST on business days will ship same day for in-stock items. HHP ships nationwide via UPS and FedEx. If you need to confirm availability before ordering, contact our team at 844.215.3406.

Yes. HHP offers financing through PayPal Pay Later and Sezzle at checkout. PayPal Pay Later lets you split the purchase into 4 interest-free bi-weekly payments or choose a monthly installment plan ranging from 3 to 24 months. Sezzle offers similar flexible options with no credit check required on select plans. HHP will finance your repair so a cooling system failure does not keep your C15, C16, or C18 sidelined any longer than necessary.
