Product Information "Cylinder head bolt"

Jaguar: XJS 4.0 with AJ16 engine from engine no. B100136 (1994-96) • X300 (XJ) 3.2 and 4.0 from VIN...720125 to 812255 (1993-97)

These so-called stretch bolts are specifically designed to give a set length under the right torque. As such they should never be used a second time. The desired bias requires careful installation. The cylinder head bolts are assembled in several stages with a specific tightening torque. When this torque is reached, the bolts are turned further through a defined angle which pre-loads them into a plastic region. We recommend that new cylinder head stretch bolts be used and any work carried out to your engine is done in accordance with a factory workshop manual. Whilst you are doing this job we consider it advisable to replace the water pump and expansion cap to minimise any future problems.
