Caterpillar 3304 Freshwater Pumps and Cooling System Components

The Caterpillar 3304 is a widely used engine found in industrial, construction, and marine applications. To keep this engine operating efficiently, its cooling system must perform at peak capacity under demanding workloads. A properly functioning freshwater pump ensures coolant is circulated through the block, cylinder head, and heat exchanger, preventing overheating and protecting critical engine components.

Diesel Pro Power provides a full selection of freshwater pumps, coolant hoses, and clamps specifically designed for Caterpillar 3304 engines. Each part is engineered to OEM-quality standards, ensuring reliable operation and long service life.

Freshwater Pumps for Caterpillar 3304

The engine water pump is the heart of the Caterpillar 3304 cooling system. Without efficient coolant circulation, engine temperatures would quickly rise, leading to head gasket failure, warped cylinder heads, or even complete engine breakdown.

Our inventory of Caterpillar 3304 freshwater pumps includes:

• Standard replacement pumps – Designed to match OEM flow rates and fitment for the 3304 engine.

• Heavy-duty pumps – Built for applications where the 3304 is pushed to its limits, such as mining, construction, or continuous-duty marine service.

• Versatile compatibility – Several pumps are also suitable for related Caterpillar engines such as the 3306 and D330, but each option in this catalog is selected for direct use on the 3304 to ensure proper fit and function.

Every pump comes ready to install and designed to restore full cooling performance to Caterpillar 3304 engines.

Coolant Hoses for Caterpillar 3304

Alongside the water pump, coolant hoses form the arteries of the engine cooling system. Over time, hoses can become brittle, crack, or collapse under pressure, restricting coolant flow. Diesel Pro Power offers premium silicone hoses for the Caterpillar 3304 that resist high temperatures, coolant additives, and long-term wear.

Available hose sizes for Caterpillar 3304 include:

• Small-diameter hoses – 3/4" and 1" options ideal for bypass and smaller coolant lines.

• Medium-diameter hoses – 1 3/4", 1 7/8", 2", and 2 1/4" hoses for primary circulation lines.

• Large-diameter hoses – Up to 4" inside diameter, ensuring reliable flow in heavy-duty applications.

These hoses are sold by the foot, making it easy to order the exact length required for your 3304 installation. Silicone construction ensures durability, flexibility, and resistance to cracking, even in high-heat conditions.

Hose Clamps for Caterpillar 3304

Every hose installation requires durable clamps to maintain a leak-free seal. Our clamps for the Caterpillar 3304 cooling system are made from corrosion-resistant materials, with smooth tightening action and a wide effective range.

Options include:

• Fuel and coolant hose clamps – Designed for secure fitment on smaller hoses (as little as 9/16").

• Heavy-duty clamps – Capable of handling larger hoses up to 3" in diameter.

• Versatile fitment – A full range ensures you can properly secure every coolant line in the Caterpillar 3304 cooling system.

With the right clamp selection, engine vibration and pressure fluctuations will not compromise your cooling system’s integrity.

Applications of the Caterpillar 3304 Cooling System

The Caterpillar 3304 engine powers equipment across multiple industries. The cooling system, driven by the freshwater pump, is essential to these demanding applications:

• Construction equipment – Excavators, loaders, and bulldozers operating in hot, dusty environments.

• Industrial machinery – Pumps, compressors, and generators running for extended hours in stationary installations.

• Marine service – Fishing boats, tugboats, and workboats relying on the 3304 for propulsion or auxiliary power.

In every case, a dependable cooling system ensures the engine runs at the correct temperature for optimal performance and extended life.

Maintenance Tips for Caterpillar 3304 Cooling System

1. Inspect hoses regularly – Look for cracks, bulges, or soft spots that indicate hose wear.

2. Check coolant levels – Low coolant can cause cavitation inside the water pump, leading to early failure.

3. Tighten clamps – Ensure all hose clamps are secure to prevent leaks.

4. Replace the water pump proactively – Pumps can wear over time; replacing before failure avoids costly downtime.

5. Use high-quality coolant – Proper coolant mixture reduces corrosion and improves thermal transfer.
