This is a replacement cylinder head bolt washer for Nissan Patrol GQ and GU models fitted with the RD28 diesel engine. It is located on top of the cylinder head, between the cylinder head and the head of the bolt. This washer is a critical component for achieving the correct clamping force and distributing the load evenly.
These washers are often damaged or lost during engine work, such as a cylinder head service or a full engine rebuild. To ensure a reliable repair, they must be replaced if they are visually damaged or missing.
This washer should be replaced as part of a complete cylinder head service. Please note that this is a complex job requiring specialised tools, including a precision torque wrench, and extensive mechanical knowledge. For a complete service, you may also require a new head gasket set, cylinder head bolts, engine oil, and coolant. Manifold gaskets may also be needed, depending on the scope of the work.
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.
