Product Features

• Structure: Made of high-quality nitrile rubber (NBR), with a precision-molded circular cross-section. The material offers excellent oil resistance, heat resistance, and elasticity.

• Performance: Maintains a tight, reliable seal between the cylinder liner and block, preventing coolant and oil from mixing. Its elasticity ensures a consistent seal even under thermal expansion and vibration.

• Design: Engineered for a precise fit with the MC11/MC13 cylinder liner, ensuring easy installation and long service life.

Core Function

• Seals the interface between the cylinder liner and engine block to prevent coolant from leaking into the crankcase and oil from entering the cooling system.

• Protects the engine’s lubrication and cooling systems from contamination, ensuring reliable operation and extending component life.

• Withstands the mechanical stress and temperature fluctuations of heavy-duty engine operation.

Key Functions & Benefits of Cylinder Liner Seal 200V96501-0534

What This Seal Does for Your Engine

The Cylinder Liner Seal 200V96501-0534 performs a critical sealing function within the SINOTRUK engine cooling system. It sits at the interface between the wet cylinder liner and the engine block, creating a watertight barrier that prevents coolant from entering the crankcase or combustion chamber.

• Prevents Coolant Leakage: Maintains a hermetic seal between the cylinder liner outer surface and the block bore, eliminating the risk of coolant contamination in engine oil.
• Withstands Extreme Temperatures: Engineered from high-grade fluoroelastomer/silicone compounds that resist thermal degradation from -40°C to +200°C continuous operation.
• Resists Chemical Attack: Formulated to withstand prolonged exposure to ethylene glycol coolants, engine oils, and combustion byproducts without swelling or hardening.
• Maintains Compression Integrity: By keeping the liner properly seated and sealed, it indirectly supports consistent cylinder compression across all operating conditions.
• Extended Service Life: Designed to match OEM replacement intervals of 300,000–500,000 km under normal heavy-duty operating conditions.
• Drop-In Fitment: Precision-dimensioned for direct installation — no machining, trimming, or adapter components required.

Benefits for Procurement Managers

• Factory-Direct Pricing: Eliminate middleman markups — source directly from our verified manufacturing partners in China.
• Bulk Order Flexibility: Whether you need 50 pieces or 50,000, we scale to your demand with consistent lead times.
• Reduced Downtime Costs: Reliable sealing performance means fewer unscheduled engine teardowns and lower total cost of ownership for your fleet.
• Full Traceability: Every batch comes with quality inspection records and material certifications upon request.

System Application

Within the engine assembly, this cylinder liner seal operates as part of the wet liner cooling system. In wet-liner engine designs, coolant flows directly around the outer surface of the cylinder liner. The 200V96501-0534 seal creates the critical barrier at the lower liner register, preventing coolant from bypassing into the oil sump. A failed seal in this position leads to coolant-oil mixing — one of the most costly and damaging failure modes in heavy-duty diesel engines.

Frequently Asked Questions (FAQ)

What are the symptoms of a failing Cylinder Liner Seal 200V96501-0534?

The most common indicators include milky discoloration in engine oil (coolant contamination), unexplained coolant level drops without visible external leaks, white exhaust smoke during warm-up, and in severe cases, engine overheating due to coolant loss. If you observe any of these symptoms in a SINOTRUK MC or D-series engine, the cylinder liner seal should be inspected immediately.

Is this Cylinder Liner Seal 200V96501-0534 an OEM-original part or aftermarket?

We supply OEM-specification replacement parts manufactured to the exact dimensional and material standards as the factory-installed seal. They are produced in ISO-certified facilities using the same grade of fluoroelastomer compounds, ensuring identical sealing performance and service life at a significantly lower procurement cost.

How many cylinder liner seals does one SINOTRUK engine require?

A standard 6-cylinder SINOTRUK MC11 or D12 engine uses one cylinder liner seal per cylinder at the lower register position — meaning 6 pieces per complete engine overhaul. Some configurations also use an upper O-ring seal (separate part number). We recommend replacing all 6 simultaneously during any liner service.

What is the recommended replacement interval for this seal?

Under normal heavy-duty operating conditions, the Cylinder Liner Seal 200V96501-0534 should be inspected at every major service interval (approximately 300,000–500,000 km) and replaced whenever the cylinder liner is removed. Seals should never be reused after liner removal, as the compression set makes them unable to re-seal reliably.

Can this seal be used with different coolant types?

Yes. The FKM-based compound is compatible with all standard ethylene glycol and propylene glycol-based coolants, including extended-life (OAT) formulations. It also resists degradation from supplemental coolant additives (SCAs) commonly used in heavy-duty diesel applications.

What is the lead time for bulk orders?

Standard stock orders ship within 3–7 business days. Large volume orders (10,000+ pieces) or custom-packaged orders typically require 15–20 business days. We maintain safety stock of high-demand SINOTRUK engine sealing components to minimize your wait time.
