1609874 Liner O Ring — Volvo FH12 FH16

This Liner O-ring is specifically designed to seal the cylinder liner within the engine block, preventing coolant from entering the combustion chamber or crankcase. It is constructed from heat-resistant and chemically stable materials that maintain their sealing properties under extreme engine operating conditions, unlike a hardened or cracked original O-ring. Operators may notice white smoke from the exhaust, coolant loss, or an increase in engine oil level if this O-ring fails.

Installation & Application Notes

Always match seal material to fluid type — NBR for petroleum, FKM (Viton) for high-temperature/chemical applications. Lubricate seals with clean fluid before fitting — never grease. Check shaft surface for scoring — rough surfaces destroy new seals within hours.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

The initial symptom of a failed liner O-ring is often the presence of white smoke from the exhaust due to coolant entering the combustion chamber. This can progress to a noticeable loss of coolant without external leaks and potential contamination of the engine oil. If left unaddressed, this condition can lead to severe internal engine damage, including bearing failure and cylinder wall scoring.

Installation Tip

Thoroughly clean the cylinder liner bore and the liner itself, ensuring no debris remains that could compromise the seal. Carefully seat the O-ring without stretching or twisting it to prevent premature failure.

Service Note

When replacing liner O-rings, it is essential to inspect the cylinder liners for wear or damage and check the condition of the engine block sealing surfaces.
