Installing a Cylinder Head
Installing a new or remanufactured cylinder head on an engine is relatively simple and requires no advanced skills. This Foley Tech Tip, one of an ongoing series, provides a guide to cylinder head installation.
Installing the Head
Carefully check the head gasket to ensure it is correct and not covering coolant holes. Place the new gasket onto the cylinder block, checking for proper alignment. Lay the head down on top of the gasket. To avoid altering torque readings clean all bolt holes. Use clean but not pre-lubed bolts or studs.
Torque Sequence
Using a torque wrench, carefully tighten the fasteners in a circular pattern starting in the center and working out to the edges. Consult Foley Tech Tip #5 for recommended torque values. Retorque the head after the initial warm up and again after 50 hours of operation. Adjust the valves at the same intervals.
