Product Description
Product Introduction C5558311 Cylinder Liner O-Ring is a critical annular seal fitted at the bottom groove of wet cylinder liner on ISZ14 diesel engine. It seals the gap between cylinder liner and engine block to block coolant from entering the crankcase, while also stopping engine oil from mixing into the cooling circuit. This aftermarket replacement O-ring fixes coolant contamination in lubricating oil, milky oil appearance and liner bottom seepage faults caused by rubber aging, compression set and chemical corrosion of old seals. Stable separation of oil and coolant circuits protects crankshaft bearings and other moving parts for heavy-duty long-haul transport fleets.
Product Advantages Made of high-performance coolant-resistant elastomer, maintaining elasticity under sustained fluctuating operating temperatures. Consistent cross-section creates uniform clamping force after repeated heating and cooling cycles. It shows strong resistance against glycol antifreeze and common coolant additives. Every batch is sampled for compression recovery and hot soak aging testing before shipment, precise dimensions for smooth installation during engine rebuild.

FAQ
Q1: What severe engine damage may happen once the liner O-ring fails completely?
A1: Coolant rushes into crankcase, dilutes lubricant and leads to bearing melting and engine seizure.
Q2: Why should technicians check the liner groove surface before placing this new O-ring?
A2: Rust pits or scratches on the groove will abrade the seal and cause recurring leakage.
Q3: Can over-tightening of cylinder head bolts exert indirect stress on the liner O-ring?
A3: Excessive bolt load distorts liner geometry, squeezing the ring unevenly and breaking the seal.
