Detroit Diesel Fresh Water Pumps — Complete Catalog by Engine & Configuration

Keeping a Detroit Diesel two-stroke or four-stroke engine at its ideal operating temperature depends on one hard-working component: the fresh water pump. It continuously circulates coolant through the block and cylinder heads (and through a heat exchanger on marine engines) to prevent overheating, stabilize clearances, and protect gaskets and seals. When a pump wears out or begins to leak, temperature control suffers, leading to unnecessary downtime and costly repairs.

Diesel Pro Power makes getting the right pump simple. Our catalog is organized by engine series, model, and configuration (including turbo vs. non-turbo, and on Series 71: non-turbo 2-valve vs. non-turbo 4-valve). Choose your exact engine below and go straight to the compatible fresh water pumps, repair kits, and thermostats. Every item you see online is in stock, ready for fast worldwide shipping, and backed by 40,000+ satisfied customers and decades of cooling-system expertise.

Installation & Service Tips (All Detroit Diesel Engines)

• Confirm configuration: For Series 71, identify non-turbo 2-valve vs. non-turbo 4-valve or turbocharged before ordering. For other series, verify turbo vs. non-turbo and front accessory drive details.
  
  

• Inspect related parts: Replace thermostats, gaskets, O-rings, and belts with the pump. Check coolant quality and pressure-test the system.
  
  

• Look for warning signs: Coolant weep-hole drips, bearing noise, belt dust, rising operating temps, or temperature swings under load typically indicate a failing pump.
  
  

• Prime and bleed properly: After installation, refill with the correct coolant mixture, bleed air pockets, and recheck level after the first run-in cycle.
  
  

• Record details: Log engine hours/miles, coolant type, and service date to plan proactive maintenance intervals.
