Product Description
C3973511 Oil Filler Cap is a threaded sealing cover installed on the engine oil filler neck of DFCV 6L diesel engine. It seals the oil adding opening and maintains proper internal pressure of crankcase ventilation system, preventing engine oil splashing out and stopping dirt and rainwater from entering the crankcase. This aftermarket replacement cap solves oil spattering, pressure imbalance and sludge buildup caused by broken locking teeth, aging sealing ring and cap cracking of original filler caps. Reliable sealing protects engine lubricating oil quality and avoids abnormal oil consumption for heavy trucks running long-hour highway freight missions.
Product Advantages Adopts high-strength modified plastic main body with integrated rubber sealing ring. The thread structure is precisely molded for smooth screwing and tight locking. The built-in pressure balancing structure matches crankcase ventilation requirements. Each oil filler cap undergoes air tightness test and thread inspection before packing, OEM thread size and outline for direct replacement.
