Cylinder head bolts are the critical fasteners that clamp the cylinder head to the block on the Land Rover 2.25 petrol engine, maintaining the head gasket seal against combustion p ressure and coolant passages. On the Series 3 2.25 petrol, stretched or fatigued head bolts are a common cause of head gasket failure, resulting in coolant loss, overheating, or combustion gas contamination of the cooling system. Correct replacement bolts ensure the specified torque is achieved and maintained throughout the engine's service life. Key Features Manufactured to suit the medium cylinder head bolt specification for the 2.25 petrol engine Head bolts should always be replaced rather than reused when the cylinder head is removed, as bolts stretch under torque cycles Matched to OEM fitment requirements for the Series 3 2.25 petrol application Replace as a complete set; inspect the head gasket, thermostat, and water pump concurrently during head removal Vehicle Fitment This part fits the Land Rover Series 3 equipped with the 2.25 Petrol engine, Medium specification.
