• Water Manifold to Oil Cooler Housing Seals: Available in multiple diameters to match your configuration, these seals maintain tight connections and prevent coolant or oil leaks.

• Thermostat Seals and Housing Gaskets: Ensure tight connections between the thermostat housing and coolant passages, maintaining system pressure and efficiency.

• Gasket for Block Water Outlet: Engineered to provide reliable sealing at the block outlet, suitable for use with block heaters or direct coolant outlets.

These gaskets and seals are made from heat- and chemical-resistant materials to withstand years of continuous operation in both marine and industrial environments.

Detroit Diesel 6V71 Turbo Thermostats

Maintaining precise engine temperature is critical for turbocharged Detroit Diesel engines. Diesel Pro Power provides several thermostat options to fit your operating environment and performance requirements.

• 160-Degree Thermostat: Best suited for engines operating in colder climates or light-duty applications.

• 170-Degree Thermostat: Commonly used for marine engines where cooling water is abundant and consistent temperature regulation is required.

• 180-Degree Thermostat: Ideal for heavy-duty truck and industrial applications that require higher operating temperatures for efficiency.

Each thermostat is precision-calibrated to ensure consistent temperature control. Replacing thermostats at regular intervals prevents overheating, ensures efficient combustion, and promotes longer engine life.

Detroit Diesel Radiator Components and Caps

Radiator caps and neck assemblies are small but vital components of the 6V71 Turbo cooling system. They maintain proper coolant pressure, helping prevent boiling and minimizing air intrusion.

• Radiator Cap – Small: Standard cap with seven-pound pressure setting for compact cooling systems.

• Radiator Cap Neck – Small: Designed for smaller cooling systems with limited space.

• Radiator Cap Neck – Large: Used on larger marine cooling systems that require higher flow and volume.

Together, these components ensure proper pressure balance and reliable heat exchange, particularly important for turbocharged engines running at higher temperatures.

Cooling System Accessories

Diesel Pro Power carries a wide selection of accessories that complement your Detroit Diesel 6V71 Turbo water pump and cooling system.

• Drain Cock Fittings: Allows easy drainage of the cooling system for servicing or winterization.

• Radiator Cleaner: A professional-grade cleaning solution formulated to remove scale, rust, and contaminants from the cooling system, restoring flow efficiency.

• Temperature Switch: Activates warning lights or alarms when coolant temperature exceeds safe operating limits.

• Detroit Diesel Engine Paint – Green: OEM-style paint that restores the original Detroit Diesel look and provides corrosion resistance on engine components.

These accessories are essential for routine maintenance and long-term system protection, keeping your engine running cooler and cleaner.

Silicone Coolant Hoses

Turbocharged engines demand durable coolant hoses that can withstand higher heat and pressure. Diesel Pro Power offers a full range of silicone coolant hoses for the Detroit Diesel 6V71 Turbo engine, available in multiple diameters and one-foot lengths for custom applications.

These hoses provide superior resistance to oil, ozone, and temperature extremes. Whether used for marine, industrial, or truck applications, they deliver reliability far beyond standard rubber hoses.

Common sizes include hoses with internal diameters from three-quarters of an inch up to four inches, covering all major coolant and bypass connections. Each hose is reinforced for pressure resistance and designed to handle constant thermal cycling without degradation.
