LML Duramax Water Pump 2011-2016 - Fleece

Overview

This is an engine water pump for the Chevrolet, GMC LML Duramax diesel (2011-2016). Built to OEM specification and engineered as a direct-fit replacement for a professional-grade LML Duramax repair or service. Every order ships fast and is backed by our support team.

What It Does & How It Helps

The water pump circulates coolant through the block, heads and radiator to carry heat away from the engine. A worn bearing gets noisy, the shaft seal starts weeping coolant, and a failing impeller lets the engine overheat under load. A new OE-spec water pump, with its gasket or seal, restores full coolant flow and reliable engine cooling — best replaced at the first sign of a leak or bearing noise, before it strands you.
