Binding Type Binding: N/A (if digital/PDF) Paper Type Paper: N/A (if digital/PDF) ⚙️ Engine Specifications Primary Engine Engine Manufacturer: Detroit Diesel Corporation (DDC) Engine Family: EPA10 compliant DDC engines (Specific model not identified in product name, but common engines in this era include DD13, DD15, DD16). Performance Horsepower Range: Variable, typically 350-600+ HP depending on specific DDC engine model. Torque Range: Variable, typically 1250-2050+ lb-ft depending on specific DDC engine model. Fuel System Fuel Type: Diesel Injection System: Common Rail (typical for EPA10 DDC engines) Emissions Control Post Treatment: Diesel Particulate Filter (DPF), Selective Catalytic Reduction (SCR) system (standard for EPA10). 🔧 Transmission Standard Transmission Options: Multiple, including Eaton Fuller manual transmissions and Allison automatic transmissions (specific models depend on truck configuration). Optional Automatic Transmission: Detroit DT12 (proprietary automated manual transmission) became prominent later, but earlier EPA10 models would use Eaton or Allison. Features Features: Depending on configuration: overdrive, PTO capabilities, various gear ratios for vocational and line-haul applications. 📐 Dimensions Exterior Cab Configurations: Conventional, Aerodynamic COE (Cab-Over-Engine) variants (e.g., Argosy, Century Class). Wheelbase: Highly variable, dependent on truck configuration and intended use (e.g., 132-270+ inches). Weights Gvwr: Ranges from Class 7 (e.g., 108SD) up to heavy Class 8 configurations, typically 33,000 lbs to 80,000+ lbs GCWR. 🛡️ Safety Features Ratings Safety Focus: Designed for commercial use, meeting stringent safety standards for driver and road safety. Active Features Active Safety: ABS (Anti-lock Braking System) is standard. Optional features may include stability control, lane departure warning, adaptive cruise control depending on specific truck build. Passive Features Passive Safety: Reinforced cab structures, driver and passenger airbags (in some configurations), seatbelt pre-tensioners. 💡 Technology Features Infotainment Infotainment Systems: Basic radio, CD player, optional navigation and communication systems available on higher trims. Focus is on functionality for long-haul drivers. Driver Assistance Adas Features: Availability varies significantly by model year and trim. May include features like lane keeping assist, collision mitigation systems (e.g., Bendix Wingman), adaptive cruise control. Connectivity Telematics: Fleet management telematics systems (e.g., Detroit Connect) often available for monitoring vehicle performance, diagnostics, and location. 🔧 Maintenance Service Intervals Cooling System Maintenance: Typically involves coolant checks, hose inspections, and coolant flushes every 30,000-100,000 miles, depending on coolant type and operating conditions. Specific intervals for the update itself would be detailed in the bulletin. Fluid Specifications Coolant Type: Heavy-duty Extended Life Coolant (ELC), typically Organic Acid Technology (OAT), often specified as a John Deere Cool-Gard II equivalent or similar. Refer to Freightliner specifications for precise type. Coolant Capacity: Highly variable by model and radiator size, typically 10-15 gallons or more.
