Parts For Detroit Diesel 12V149 Non-Turbo for Canada - Oil Cooler Section

Parts for Detroit Diesel 12V149 Non-Turbo – Oil Cooler Section

The Detroit Diesel 12V149 Non-Turbo engine stands as one of the most robust and powerful members of the legendary 149 Series, designed to handle the most demanding industrial, marine, and power generation applications. With its twelve cylinders arranged in a 90-degree V configuration and a total displacement of 1,794 cubic inches (29.4 liters), this two-stroke diesel engine was engineered for endurance and steady performance under heavy load. Whether used in large vessels, generator sets, or heavy-duty equipment, maintaining an optimal oil cooling system is essential for keeping this engine performing at peak efficiency.

At the core of the lubrication and thermal management system lies the oil cooler, which ensures that engine oil maintains the correct temperature to protect internal components and extend the engine’s operational lifespan. The 12V149 Non-Turbo, due to its large displacement and continuous power output, depends heavily on a clean, efficient oil cooler, compatible gaskets, and pressure components that regulate and protect its internal flow systems. Below, we explore the key components that make up the Oil Cooler Section for the Detroit Diesel 12V149 Non-Turbo and how each contributes to engine reliability, followed by detailed insight into Diesel Pro Power’s high-quality replacement parts.

Detroit Diesel Oil Cooler – 30 Plates

The Detroit Diesel 12V149 Oil Cooler (30 Plates) is a precision-engineered heat exchanger designed to regulate oil temperature by transferring excess heat into the coolant system. In an engine as large and powerful as the 12V149, oil temperature stability is critical — overheating can rapidly degrade oil viscosity, leading to insufficient lubrication and metal-to-metal contact within bearings, crankshaft journals, and camshaft assemblies.

This 30-plate cooler features a stacked-plate design, providing a large surface area for optimal heat exchange efficiency while maintaining a compact profile suitable for the 149 Series block. Constructed from high-grade materials designed to resist corrosion and fatigue, the cooler is built to handle high oil pressure and continuous operation under marine or industrial conditions.

Diesel Pro Power supplies brand-new oil coolers that match OEM specifications, ensuring direct fitment without modifications. Each unit undergoes thorough quality testing to confirm leak-free operation and heat transfer performance comparable to factory standards.

Key Advantages:

• Designed for high-capacity Detroit Diesel 12V149 Non-Turbo engines.

• 30-plate design provides superior thermal efficiency.

Detroit Diesel Oil Cooler Gasket Kit for 8V149, 12V149 & 16V149 Engines

No oil cooler installation or maintenance is complete without a high-quality gasket kit. Diesel Pro Power’s Oil Cooler Gasket Kit is designed for the 8V149, 12V149, and 16V149 engines, offering precision-fit seals to prevent oil and coolant cross-contamination. Each gasket is made from advanced composite materials capable of withstanding extreme temperature fluctuations, high pressure, and continuous vibration.

Proper gasket performance is vital to maintaining system integrity. A leaking oil cooler gasket can result in coolant entering the oil passages or vice versa — a situation that can cause catastrophic engine damage. Using new, high-quality gaskets during service ensures the longevity of your oil cooler assembly and the entire lubrication circuit.

Gasket Kit Features:

• Includes all necessary seals and gaskets for complete oil cooler installation.

• Engineered to resist oil, coolant, and thermal breakdown.

• Suitable for multiple 149 Series configurations (8V149, 12V149, 16V149).

• Precision cut for perfect alignment and sealing surfaces.

• One kit required per oil cooler unit.

By installing a fresh gasket set, operators can restore full sealing integrity to their cooling system, preventing leaks and ensuring efficient oil circulation under heavy-duty operation.

Detroit Diesel Gasket Kit for Oil Pan – 12V149 Engines

The oil pan gasket kit for the Detroit Diesel 12V149 Non-Turbo engine ensures proper sealing between the oil pan and the engine block. Given the massive oil capacity of the 12V149 — necessary to lubricate twelve cylinders and multiple moving assemblies — maintaining a secure, leak-free oil pan is crucial to system health.

Diesel Pro Power’s Oil Pan Gasket Kit provides all required gaskets for resealing the oil pan after maintenance or overhaul. The design focuses on durability and precision fitment, eliminating oil seepage and pressure loss that could compromise lubrication efficiency.

Benefits of Using a New Oil Pan Gasket Kit:

• Prevents oil leaks and contamination.

• Manufactured to OEM standards for 12V149 engines.

• Resistant to expansion, shrinkage, and heat cycling.

• Ensures proper oil pressure retention for all operating conditions.

This gasket kit is particularly important during full engine rebuilds or when replacing the oil cooler assembly, as the oil pan may need removal for cleaning or inspection of internal components.

Oil Filter for Detroit Diesel & Cummins Engines – Spin-On Type

An oil filter serves as the first line of defense against contaminants that can harm the Detroit Diesel 12V149 engine. Diesel Pro Power supplies spin-on oil filters that combine high filtration efficiency with easy installation. These filters trap microscopic particles, carbon residue, and sludge that accumulate through regular engine operation.

Maintaining a clean oil supply reduces wear on bearings, pistons, and camshaft lobes, ensuring smooth operation and extending overhaul intervals. The spin-on design simplifies filter changes, making it ideal for both field service and onboard marine maintenance.

Oil Filter Highlights:

• Designed for both Detroit Diesel and Cummins applications.

• Spin-on type simplifies installation and replacement.

• Maintains optimal oil cleanliness and pressure balance.

• Built to withstand high oil temperatures and flow rates of large diesel engines.

Operators should replace oil filters according to manufacturer recommendations or after every oil change to maintain top lubrication system performance.

Fuel & Oil Pressure Switches (5, 10, 20, and 27 PSI Make/Break)

Pressure switches are critical components in monitoring oil and fuel pressure levels, ensuring the engine’s lubrication and fuel systems operate within safe limits. Diesel Pro Power offers a range of make/break pressure switches calibrated at 5, 10, 20, and 27 PSI for Detroit Diesel and Cummins applications.

Each switch is built with a durable brass housing and reliable internal contacts to ensure consistent activation and deactivation points. These switches can be used to control warning alarms, safety shutdown systems, or indicator lights, providing essential real-time feedback to the operator.

Available Variants:

• 5 PSI Make/Break Switch: Ideal for low-pressure alarm systems, ensuring early detection of oil pressure loss.

• 10 PSI Make/Break Switch: Commonly used for general engine oil pressure warning circuits.

• 20 PSI Make/Break Switch: Provides mid-range monitoring suitable for large displacement engines under variable loads.

• 27 PSI Make/Break Switch: Used in high-performance or continuous-duty configurations requiring higher pressure sensitivity.

Each pressure switch features a 1/8” NPT thread for universal fitment and compatibility across multiple Detroit Diesel configurations.

Mechanical & Electric Gauges for Pressure Monitoring

For complete visibility over the 12V149’s lubrication and cooling systems, Diesel Pro Power provides a full line of mechanical and electric gauges, available in both 12-volt and 24-volt versions. These gauges measure oil pressure, oil temperature, and other vital parameters that ensure your Detroit Diesel engine is operating safely.

Types of Gauges:

• Mechanical Standard Gauges: Ideal for direct engine installations where electrical power is not required.

• Mechanical Gauges with Alarm: Provide both real-time readings and warning triggers when pressures deviate from safe ranges.

• Electrical Gauges (12V and 24V): Designed for marine control panels, offering accurate and stable readings for remote engine monitoring.

By integrating gauges with pressure switches, operators gain comprehensive protection against low oil pressure or overheating events that could damage the 12V149’s internal components.
