Water Pump Assemblies for Cummins 6B Engines

The engine water pump plays a central role in maintaining coolant circulation throughout the Cummins 6B engine block and cylinder head. Our selection includes:

Freshwater Pump Options:

• Direct-fit replacement pumps for a wide range of CPL configurations (including 1975, 2122, 8266, 8306, 2893, and more)

• Marine-grade corrosion resistance for use in saltwater environments

• Long-life bearing systems and high-efficiency impellers

• Designed to meet or exceed OEM specifications

These pumps are essential for maintaining consistent operating temperatures and avoiding engine overheating, especially during high-load or continuous operation.

Water Pump Sealing Components

Even the highest-quality water pump can fail prematurely without proper seals. Diesel Pro Power provides:

Seal Ring:

• Designed for the Cummins 6B water pan

• Resists coolant erosion and prevents leaks

Replacing seals during pump installation ensures long-term coolant containment and optimal pump performance.

Thermostats & Temperature Regulation Components

The Cummins 6B engine requires precise thermal regulation. We stock both 165°F and 180°F thermostats to suit a variety of operating conditions.

Available Thermostats:

• 165°F: For warm environments or heavy-duty applications

• 180°F: Ideal for rapid warm-up in colder conditions

Thermostat Components:

• Thermostat seals designed for ISB and QSB compatibility

• Housing gaskets for leak-free installation

Thermostats play a vital role in regulating engine temperature and must be replaced periodically to maintain performance.

Coolant Filtration

Over time, coolant can carry particulates that degrade system performance. Diesel Pro Power carries:

Coolant Filter:

• Helps remove rust, scale, and debris from the coolant loop

• Extends the lifespan of the water pump, thermostat, and radiator

Adding or replacing a coolant filter is an excellent preventive measure for marine and industrial Cummins 6B engines.

Belt Tensioners for Pump & Accessory Drive

Proper belt tension ensures that accessories such as the water pump, alternator, and cooling fan operate at the correct speed. Options include:

Tensioner Options:

• Plain pulley tensioners

• Grooved pulley tensioners for improved grip and alignment

These components help maintain consistent belt performance, reducing wear and preventing misalignment.

Drive Belts for Cummins 6B Engine Accessories

Our inventory includes serpentine V-belts with an 8-rib design, engineered to drive water pumps, alternators, and fans:

Available Belt Lengths:

• 53.50”, 57.5”, 59”, 59.5”, 60.0”, 66.53”, 66.92”, 69.0”

Each belt is manufactured to handle high loads and frequent cycling, offering optimal durability in industrial environments.

Radiator & Cooling System Maintenance

Proper cooling system function goes beyond hardware:

Radiator Cleaner:

• Removes rust, limescale, and debris

• Improves coolant flow and heat transfer

Temperature Switch:

• Activates fans or alarms at 205°F

• Suitable for Cummins, Detroit Diesel, and Caterpillar engines

These maintenance components help prevent overheating and keep your system clean and responsive.

Silicone Coolant Hoses

Durable silicone hoses resist high temperatures and chemicals better than standard rubber:

Available Inside Diameters:

• 3/4", 1", 1 3/4", 1 7/8", 2", 2 1/8", 2 1/4", 2 3/8", 2 1/2", 2 3/4", 3", 3 1/2", 4"

Each hose is sold in 1-foot lengths and reinforced for long-term use in high-demand cooling systems.

Hose Clamps for Coolant & Fuel Systems

Pair your hoses with our selection of heavy-duty clamps:

Clamp Features:

• Stainless steel for corrosion resistance

• Adjustable diameter ranges from 9/16" to 3.5"

• Secure grip for marine and industrial applications

These clamps ensure a leak-proof seal under vibration and thermal cycling.
