Ensure precise cylinder head alignment with this Genuine Nissan Engine Block to Cylinder Head Dowel, designed specifically for Nissan Patrol GQ and GU models fitted with the RD28 diesel engine. This OEM locating dowel accurately positions the cylinder head on the engine block, ensuring correct head gasket alignment and even clamping during assembly.

During cylinder head removal or engine rebuilds, dowel pins can become corroded, damaged, or misplaced. Installing the cylinder head without correctly positioned dowels can result in head misalignment, poor gasket sealing, coolant or oil leaks, compression loss, and premature head gasket failure.
