VOLVO 20949868 Cylinder Head Gasket | VOE20949868 / 20798075 MLS Seal Specification

Genuine VOLVO Cylinder Head Gasket 20949868 Specification

The Genuine VOLVO Cylinder Head Gasket (20949868 / VOE20949868 / 20798075) is a high-performance MLS sealing part for inline diesel engines. Installed between cylinder block and cylinder head, it locks high combustion pressure and isolates coolant passages from lubrication oil channels. Multi-layer steel structure maintains stable elastic resilience. Replacing defective gasket prevents gas leakage and fluid mixing, balances cylinder compression and avoids engine deformation damage.

Core Technical Advantages

  • MLS Multi-Layer Steel Design Premium spring steel layers possess outstanding elasticity and recovery capacity to withstand frequent combustion impact pressure.

  • High Temperature Viton Coating Fine surface coating fills tiny gaps and realizes complete isolation of liquid and gas medium.

  • Reinforced Embossed Fire Ring Effectively resist high-temperature flame and block penetration of high-pressure combustion gas.

  • Strong Chemical Stability Resist corrosion from coolant, diesel fuel and synthetic oil, keep stable sealing performance under complex working conditions.

Critical B2B Procurement & Maintenance Guidelines

B2B Procurement Strategy

Cylinder head gasket is core upper engine overhaul component. Inferior gasket is prone to blowout, causing oil coolant mixing and internal wear failure. Engine disassembly and repair cost is extremely high. Suppliers and repair workshops are recommended to stock original 20949868 gaskets. Match with head bolts, manifold gaskets and valve seals to assemble complete top end overhaul kit.

Common Failure Symptoms

  • Thick white exhaust smoke appears, coolant consumption rises sharply due to medium channel crossing

  • Milky oil emulsion forms inside engine, mixed fluid generates corrosive sludge damaging internal moving parts

  • Continuous air bubbling inside expansion tank, combustion gas invades cooling circulation system

Standard Overhaul Installation Operation
Park machine on flat ground, retract working arm, shut down engine and disconnect power, cool down fully for over 2 hours. Drain coolant and remove intake and exhaust pipelines. Loosen head bolts following reverse torque sequence and lift cylinder head safely. Inspect joint flatness and conduct grinding correction if deformed. Clean mounting surface thoroughly without scratching metal surface. Install dry gasket without extra sealant. Use brand-new head bolts, tighten step by step per factory torque and angle standard. Reassemble accessories, refill oil and coolant, start engine and check no leakage, stable pressure and normal operating temperature.
