Maintain proper sealing and prevent oil leaks with this Genuine Nissan Alternator Oil Seal, designed for early Nissan Patrol GQ Y60 TD42 models fitted with the rear-mounted alternator vacuum pump. This OEM seal is responsible for preventing engine oil from leaking through the vacuum pump and alternator assembly during operation.

Over time, the original oil seal can harden, crack, or wear from constant exposure to heat and engine oil. A failing seal may cause oil leaks around the alternator, contamination of surrounding components, or reduced reliability of the vacuum pump assembly. Replacing the seal helps restore proper sealing performance and protects critical engine bay components from oil contamination.

Manufactured to genuine Nissan specifications, this direct-fit replacement delivers precise fitment, long-lasting durability, and dependable sealing performance in harsh off-road, towing, and everyday driving conditions.
