GE Locomotive Cylinder Head – Complete Guide & Global Supply
The GE Locomotive Cylinder Head is one of the most essential components in GE 7FDL and GEVO engines, responsible for combustion efficiency, fuel control, and overall engine performance. ASA Engine Equipments has been supplying premium-quality GE cylinder heads worldwide for more than 20 years, supporting railway operators across the USA, Canada, Australia, Germany, France, Bangladesh, UK, Mexico, Italy, Romania, Austria, Turkey, Mozambique, Sri Lanka, Senegal, and Republic of Liana.
This comprehensive guide covers construction, design, benefits, specifications, troubleshooting, installation tips, and global supply details — all optimized for ranking on Google SERP.
What is a GE Locomotive Cylinder Head?
A cylinder head is mounted above the engine block, sealing the top of the cylinder and forming the combustion chamber. It houses essential components such as:
- Fuel injectors
- Valves
- Valve seats
- Rocker arm assemblies
- Ports & cooling passages
A well-engineered GE cylinder head ensures proper air–fuel mixture, pressure control, heat management, and efficient combustion.

Our GE cylinder heads are compatible with:
Compatible GE Engine Models
Our GE cylinder heads are compatible with a wide range of locomotive engines, including:
GE 7FDL Engines (12, 16 & 20 Cylinder)
The 7FDL series is widely used in heavy freight locomotives around the world. Cylinder heads for these engines are designed to handle extreme pressure, high temperatures, and long-hour operations.
GEVO Engine Series – Evolution Series
These are advanced, fuel-efficient, low-emission engines used in modern rail systems. GEVO cylinder heads offer improved airflow, combustion precision, and better fuel performance.
Dash-8 & Dash-9 Series
These locomotives are known for reliability and durability. High-strength cylinder heads ensure long operational life and reduced downtime.
Key Features of GE Locomotive Cylinder Heads
1. High-Strength Alloy Steel Construction
Every cylinder head is manufactured using heat-resistant alloy steel designed to withstand extreme combustion temperature cycles and structural stress.
This reduces the risk of thermal cracking and ensures stable long-term performance.
2. Precision CNC-Machined Surfaces
All sealing surfaces are CNC-machined to achieve perfect alignment with the engine block.
This minimizes compression leakage and guarantees smooth engine operation.
3. Optimized Intake & Exhaust Port Design
The port geometry is engineered for maximum airflow efficiency.
Improved air intake and exhaust flow result in better combustion, reduced emissions, and increased engine power.
4. Advanced Cooling Channels
Integrated coolant passages maintain consistent engine temperature.
This helps prevent overheating and keeps the engine stable, especially in demanding environments like Australia, Bangladesh, Mozambique, and Sri Lanka.
5. Pre-Fitted Valve Seats & Guides
Each cylinder head includes hardened valve seats and guides for extended durability.
These components ensure smooth valve movement, minimal pressure loss, and long service intervals.

Benefits of High-Quality GE Cylinder Heads
- Improved Combustion Efficiency
A good cylinder head controls airflow and fuel burn more efficiently.
This results in better engine power, smoother operation, and reduced fuel costs.
- Reduced Engine Downtime
Strong materials and tested durability ensure long service cycles.
Rail operators benefit from fewer breakdowns and lower maintenance costs.
- Extended Engine Lifespan
When the cylinder head is high-quality, it supports pistons, valves, and injectors perfectly.
This prevents premature wear and increases the entire engine’s operational lifespan.
- Lower Fuel Consumption
Optimized combustion chambers increase energy extraction from fuel.
Rail operators save significantly on fuel over long-distance operations.
- Better Heat Management
Cooling channels and heat-resistant design prevent thermal distortion.
This is crucial in hot climates like Australia, Bangladesh, Mozambique, and Sri Lanka.
Common Issues & Troubleshooting
- Cylinder Head Cracks
High temperature cycles can cause cracks.
Fix: Regular temperature monitoring & coolant system checks.
- Valve Leakage
Worn-out valve seats may cause power loss.
Fix: Replace seats or switch to hardened seats included in ASA heads.
- Coolant Leakage
Failed gaskets can cause coolant to enter combustion chambers.
Fix: Ensure proper torque tightening during installation.
- Injector Sleeve Wear
Leads to fuel mixture inconsistency.
Fix: Replace sleeves at regular intervals.
Installation Tips for Long-Term Performance
- Use GE-approved torque sequence when tightening cylinder head bolts
- Clean engine block surface before installation
- Ensure correct gasket placement
- Prime the cooling system before starting
- Check valve clearance after installation
- Inspect injector sleeve seating
- Use certified lubricants and coolant
These steps significantly extend the life of the cylinder head.
