Product Features

• Structure: Cast from high-strength alloy cast iron, this is an inline 6-cylinder, 4-valve per cylinder design. It integrates intake/exhaust ports, injector bores, and coolant passages, with pre-installed valve guides and seats.

• Performance: Precision-machined combustion chambers and valve seats ensure optimal airflow and fuel atomization, supporting high engine efficiency and low emissions. The cast iron construction provides excellent heat resistance and rigidity.

• Design: Modular assembly with pre-installed valve components, simplifying engine overhaul and reducing maintenance time.

Core Function

• Seals the top of the cylinder block to form the combustion chamber, containing high-pressure gases during the power stroke.

• Houses the intake and exhaust valves, controlling airflow for efficient combustion and exhaust gas evacuation.

• Contains coolant passages to dissipate heat from the combustion process, preventing overheating and ensuring stable engine performance.

Key Features and Benefits of Engine Cylinder Head 202-03100-6455

Precision-Engineered for SINOTRUK MC Series Engines

This engine cylinder head is manufactured to match the exact dimensional tolerances and metallurgical standards required by SINOTRUK’s MC11 and MC13 engine platforms. Every combustion chamber, valve seat, and coolant passage is machined to ensure a perfect seal under extreme thermal and mechanical stress.

Superior Material Composition

Cast from high-grade alloyed gray iron with optimized carbon and silicon content, this cylinder head resists thermal fatigue, warping, and micro-cracking — even after tens of thousands of operating hours under heavy load conditions.

Core Functional Advantages

• Combustion Chamber Sealing: Maintains consistent compression ratios across all cylinders, preventing power loss and excessive fuel consumption.
• Valve Train Integration: Precisely machined valve guides and seat inserts ensure accurate valve timing, reducing emissions and maximizing torque output.
• Coolant & Oil Passage Integrity: Engineered internal channels deliver uniform cooling and lubrication, preventing hot spots that lead to premature head gasket failure.
• High Thermal Resistance: Withstands sustained operating temperatures exceeding 400°C at the combustion face without deformation.
• Drop-In Replacement: Bolt-on fitment with no modifications required — minimizes vehicle downtime and labor costs.

Frequently Asked Questions (FAQ)

What symptoms indicate that my engine cylinder head needs replacement?

Common signs include persistent coolant loss without visible external leaks, white smoke from the exhaust (coolant entering combustion chambers), engine overheating, milky residue on the oil filler cap, and noticeable compression loss across cylinders. A pressure test can confirm whether the cylinder head has cracked or warped beyond serviceable limits.

Is this engine cylinder head an exact match for OEM part 202-03100-6455?

Yes. This cylinder head is manufactured to replicate all critical dimensions, material properties, and performance characteristics of the original SINOTRUK OEM part number 202-03100-6455. It functions as a direct drop-in replacement with no machining or modification required.

What is the recommended torque sequence when installing this cylinder head?

Follow the SINOTRUK MC-series workshop manual torque procedure: tighten head bolts in three stages (initial 60 Nm → 120 Nm → final angle torque 90°+90°) using the factory-specified star pattern sequence from center outward. Always use new head bolts and a new head gasket during installation.

Can this cylinder head withstand high-altitude and extreme-temperature operating conditions?

Absolutely. The alloyed cast iron composition and precision heat treatment process ensure stable performance across a wide thermal range — from sub-zero cold starts to sustained high-load operation in hot climates or high-altitude environments where cooling efficiency is reduced.

Does the cylinder head come with valve seats and guides pre-installed?

Yes, this cylinder head is supplied as a bare head assembly with valve seat inserts and valve guides already pressed and finish-machined to specification. Valves, springs, and camshaft components are sold separately.

What is the typical lead time for bulk orders?

Standard stock orders ship within 3–5 business days. For bulk quantities (20+ units) or custom-packaged orders, typical lead time is 10–15 business days depending on current inventory levels.
