This is a genuine Nissan long stud, a critical fastening component for the ZD30DI engine. It is located on the front of the engine, passing through the water pump and timing cover to secure them firmly to the engine block. As a precision-engineered, high-tensile steel stud, it is designed to provide the exact clamping force and alignment required for these vital components, ensuring a leak-free seal.
Over time, these studs can corrode, stretch, or become damaged, particularly during a water pump or timing chain replacement. A compromised stud can cause significant coolant leaks, leading to engine overheating and potential water pump misalignment. This stud is usually replaced along with the water pump, timing cover gaskets, and fresh coolant during a major service. Replacement is considered a workshop-level job that requires significant engine disassembly.
Please check vehicle fitment to confirm compatibility with your vehicle. Please contact us with your VIN details if you require further assistance to confirm fitment.
When you're working on critical engine components, there is no substitute for Genuine Nissan quality. This stud is manufactured from high-tensile steel to Nissan's exacting standards, providing the correct clamping force that many aftermarket alternatives fail to achieve. Using an inferior, non-spec stud risks incorrect tension, coolant leaks, overheating, and potentially catastrophic engine failure if it breaks. Stick with the part designed for your Patrol.
