Parts For Detroit Diesel 16V149 Non-Turbo – Engine Fresh Water Pump (Coolant Pump) Catalog

The Detroit Diesel 16V149 Non-Turbo engine relies on a robust closed-loop fresh water (coolant) pump system to maintain stable operating temperatures under heavy-duty use. Unlike raw water pumps, which draw seawater for marine cooling, the fresh water pump continuously circulates coolant through the engine block, cylinder heads, and radiators or heat exchangers. For an engine as large and powerful as the 16V149, coolant circulation is critical to preventing overheating, maintaining consistent combustion chamber conditions, and extending the life of internal components.

Below is the complete catalog of fresh water pump assemblies, gaskets, seals, thermostats, radiator components, hoses, clamps, and supporting hardware available for the Detroit Diesel 16V149 Non-Turbo engine. All items are premium aftermarket quality, engineered to meet or exceed Detroit Diesel specifications, and are backed by Diesel Pro Power’s proven track record with over 40,000 satisfied customers worldwide.

Fresh Water Pump Assembly for Detroit Diesel 16V149

Detroit Diesel Engine Water Pump – Rebuilt

• Sold with refundable core deposit

• Heavy-duty construction to withstand the demands of the 149 Series engines

• Precision balanced impeller for efficient coolant flow

• Designed for continuous-duty marine and industrial use

This pump ensures proper circulation of coolant throughout the 16-cylinder V-block, helping to dissipate the immense heat generated under load. Proper water pump function is essential for preventing cylinder liner scoring, piston overheating, and head gasket failure.

Gaskets & Seals for Fresh Water Pump System

Detroit Diesel Gasket for Fresh Water Cover

• Ensures a leak-free seal between the coolant pump cover and housing

• Resistant to heat, pressure, and long-term coolant exposure

Thermostat Seal

• Provides a tight fit around the thermostat to prevent coolant bypass leaks

• Maintains system pressure and improves temperature regulation

These gaskets and seals are small but critical components. A compromised seal can lead to coolant loss, air intrusion, or reduced pump efficiency, all of which put the 16V149 at risk of overheating.

Thermostats for Detroit Diesel 16V149

Thermostat – 170 Degrees

• Maintains optimal coolant temperature for performance and fuel efficiency

Thermostat – 160 Degrees (for V71 & V92 compatibility)

• Alternate rating for cooler operation in marine or high-load environments

Thermostats regulate the flow of coolant between the engine and the radiator or heat exchanger. On an engine the size of the 16V149, proper thermostat selection ensures stable operating temperature whether the engine is used for propulsion, power generation, or industrial duty.

Radiator Components

Detroit Diesel Radiator Cap (7 lbs pressure)

• Regulates pressure inside the cooling system to prevent boiling

• Maintains system integrity for consistent coolant flow

Radiator Cap Neck

• Heavy-duty housing designed for small-cap fitment

Radiator Cleaner

• Safe cleaning solution to remove scale and deposits from cooling passages

• Improves heat transfer and system efficiency

Detroit Diesel Green Engine Paint

• Protective finish designed for Detroit Diesel engines

• Maintains OEM look and provides corrosion resistance on cooling components

Coolant Hoses – Silicone Reinforced

The catalog includes a full range of premium silicone coolant hoses for the Detroit Diesel 16V149 Non-Turbo engine. Silicone hoses are superior to rubber alternatives because they withstand extreme heat, pressure, and long-term chemical exposure.

Available sizes:

• 3/4" ID

• 1" ID

• 1 3/4" ID

• 1 7/8" ID

• 2" ID

• 2 1/8" ID

• 2 1/4" ID

• 2 3/8" ID

• 2 1/2" ID

• 2 3/4" ID

• 3" ID

• 3 1/2" ID

• 4" ID

Each size is available by the foot, allowing operators to replace sections of coolant line as needed without purchasing full-length industrial hose.

Hose Clamps

To secure coolant hoses under heavy vibration and high-pressure circulation, the catalog includes multiple heavy-duty hose clamps.

• Small-diameter clamps (effective range 9/16" – 1 1/16") for smaller bypass hoses

• Mid-size clamps (effective range 1" – 2 1/4") for radiator and circulation lines

• Large clamps (effective range up to 3.5") for main coolant lines

These clamps ensure leak-free connections and reduce the risk of hose blow-off under load.

Supplemental Cooling Accessories

Drain Cock Fitting (1/4")

• Allows controlled draining of coolant from the system

• Useful for maintenance, winterization, or coolant replacement

Mechanical & Electrical Gauges

• Mechanical gauges with alarm functions

• Electrical gauges for 12V and 24V systems

• Allow operators to monitor coolant temperature and pressure in real time
