Product Introduction: Toyota 15B Cylinder Head
Overview
The Toyota 15B Cylinder Head is a high-quality engine component designed for the Toyota 15B series engines, specifically the 15B-F and 15B-FT (turbocharged) variants. These 4.1-liter, inline four-cylinder diesel engines were introduced in 1994 and are commonly found in Toyota’s heavy-duty vehicles, such as the Coaster bus, Mega Cruiser, and Dyna truck. Manufactured to OEM specifications, the 15B Cylinder Head is available in bare or complete configurations (with valves and camshafts), making it an ideal choice for engine repairs or rebuilds in industrial and commercial applications. Known for its robust construction, this cylinder head ensures reliable performance under demanding conditions.
Key Features
- Material: Constructed from cast iron, offering superior durability, heat resistance, and strength, which is essential for diesel engine longevity and high-torque output.
- Design: Features a single overhead camshaft (SOHC) configuration with 16 valves (4 per cylinder), precision-machined intake and exhaust ports for optimized airflow, and compatibility with direct injection systems.
- Compatibility: Engineered for Toyota 15B series engines, including:
- Toyota Coaster (BB50, BB58; 1994-2000)
- Toyota Mega Cruiser (BXD10; military and civilian models)
- Toyota Dyna (BU212, BU222; 2000+)
- Variants: 15B-F (naturally aspirated) and 15B-FT (turbocharged)
- Part Numbers: Common OEM references include 11101-58100 and 11101-58091.
- Configuration Options: Available as a bare cylinder head or fully assembled with valves, springs, and camshafts, catering to diverse repair needs.
Technical Specifications
- Engine Fitment: Toyota 15B-F, 15B-FT (4.1L, 4-cylinder diesel)
- Material: Cast iron
- Valve Configuration: 16-valve SOHC (specific valve sizes vary by supplier, typically larger for diesel efficiency).
- Displacement: 4,104 cc (4.1 liters)
- Power Output: Supports 130-155 HP, depending on turbocharging and tuning.
- Weight: Approximately 50-60 lbs (22-27 kg), varying by configuration (bare vs. complete).
Performance Benefits
The Toyota 15B Cylinder Head enhances engine performance by:
- Ensuring robust sealing of the combustion chamber, maintaining high compression ratios (typically 18.6:1 for the 15B series) for efficient diesel combustion.
- Supporting enhanced airflow through well-designed ports, improving torque and fuel efficiency, critical for heavy-duty applications.
- Providing thermal stability under high operating loads, especially in turbocharged 15B-FT models, which produce up to 155 HP and 382 Nm of torque.
Applications
This cylinder head is vital for maintaining the operational reliability of Toyota vehicles powered by the 15B engine, including:
- Medium-duty buses (e.g., Coaster) for passenger transport.
- Military and off-road vehicles (e.g., Mega Cruiser) for rugged terrain.
- Commercial trucks (e.g., Dyna) for logistics and delivery.
- Aftermarket rebuilds and OEM replacements in industrial settings.
Installation Considerations
- Compatibility Check: Verify engine variant (15B-F or 15B-FT) and part number (e.g., 11101-58100) for proper fitment.
- Required Components: Installation typically requires a new head gasket, head bolt set (e.g., torque-to-yield bolts), and possibly a full engine overhaul kit.
- Torque Specifications: Follow Toyota’s multi-stage torque sequence (e.g., initial torque of 40 Nm, followed by angle tightening of +90° twice) to ensure proper seating.
- Professional Installation: Advised due to the complexity of diesel engine assembly and the need for precise alignment and sealing.
Why Choose the Toyota 15B Cylinder Head?
Cost-Effective Solution: Provides a practical alternative to full engine replacement, extending vehicle lifespan.
