Maintain precise injector alignment and fuel sealing in your Nissan Patrol’s diesel engine with this Genuine Nissan Injector Thimble Seat, designed for TD42, TD42T, and TD42Ti engines in GQ Y60 and GU Y61 models. This OEM injector seat sits between the injector and cylinder head, helping support the injector, ensure correct spray pattern seating, and prevent combustion gas and oil leakage.

Over time, injector thimble seats can wear, corrode, or become compressed from heat cycles, high combustion pressure, and long-term use. A worn or damaged thimble seat can lead to injector leaks, poor fuel atomisation, rough idle, reduced power, increased smoke, and even misfires.

Manufactured to Nissan’s original specifications, this direct-fit replacement ensures accurate injector seating, reliable performance, and long-lasting durability without modification.
