6.6L LLY Waterpump

2001 – 2004 6.6L Chev/GMC LLY Duramax Waterpump

Is your 6.6L LLY due for some upgrades? Consider replacing your engine’s water pump with the DFC Diesel 6.6L LLY water pump for 2001 – 2004 models! Over time, your engine’s water pump sealing and gaskets can break down or wear out, resulting in vibrations from the pump, overheating, and coolant leaks. Replacing your engine’s aging OEM pump with a DFC 6.6L LLY water pump means upgrading your engine with quality materials and remanufacturing processes to ensure your engine can handle higher temperatures and engine stress.

Designed for longevity, our water pumps feature improved impeller design and bearings for coolant circulation and efficiency, even under the most demanding towing or heavy-duty driving applications.

If you purchase a new DFC Diesel 6.6L LLY diesel engine, we recommend upgrading your water pump if your engine is over 200,000 km (125,000 miles).
