2W-8002 2W8002 Water Pump for Caterpillar 3306 3304 Engines

Stop Overheating in Your Heavy-Duty Caterpillar Fleet

The legendary Caterpillar 3304 and 3306 diesel engines are the relentless heartbeat of your most demanding equipment. However, when these workhorses are pushed to the limit in harsh quarries, dusty logging sites, or mass earthmoving projects, a worn water pump can lead to rapid coolant loss and catastrophic engine failure. Engineered to meet and exceed strict factory heavy-duty specifications, the 2W-8002 Water Pump restores maximum coolant circulation, ensuring your Cat fleet runs at optimal temperatures all day long.

The 2W-8002 Engineering Advantage

• Universal Drop-In Integration: Rebuilding a hard-working engine requires parts that fit right the first time without custom adjustments. This premium aftermarket assembly is engineered as a direct bolt-on replacement for massive OEM part numbers including 2W-8002, 172-7766, 155-0067, and 7N-5908. It guarantees flawless gasket alignment and pulley fitment on the 3304 and 3306 blocks.

• Maximum Flow Cast Iron Impeller: Constructed with a heavy-duty, precision-machined cast iron impeller designed to maximize fluid displacement. This effectively prevents block cavitation and dangerous hot spots, whether you are dragging timber with a 518 Skidder or hauling dirt in a D300B Articulated Truck.

• Severe-Duty Bearing & Seal System: Equipped with high-capacity, unitized bearings and an advanced mechanical seal assembly. It is specifically designed to withstand excessive fan belt tension, continuous heavy engine vibration, and aggressive job site elements for a leak-free lifespan.
