• Pontiac marketed its Phoenix, a compact car, from 1977 until 1984. During its short lifespan, it progressed through two generations of frames. In 1978, the Phoenix was a rear-wheel-drive car, and was available as a two-door coupe or a four-door sedan. It had a three-speed manual, a three-speed automatic or a four-speed manual transmission. To ensure engine stability, engine bolts must be torqued or bolted down to a certain weight specification under manufacturer guidelines.
  
  

Cylinder Head

• In an engine, the cylinder head, also known simply as the head, sits atop the cylinders on the cylinder block. The apparatus consists of a platform that includes valves and spark plugs.
  
  

Torque Specifications

• The main bearing caps of the cylinder head require 92 foot-pounds of torque to bolt properly to the engine block.
  
  The intake manifold, which distributes air or a combustion mixture to the intake ports of the cylinder heads, requires 37 foot-pounds of torque to join to the cylinder head.
  
  The exhaust manifold, which collects the engine exhaust from the cylinders and expels it through the exhaust pipe, bolts to the cylinder head with 39 foot-pounds of torque.
  
  

Other Specifications

• The alternator joins to the cylinder head with 33 foot-pounds of torque. The rocker arm requires 20 foot-pounds of torque to join to the cylinder head. The spark-plug-to-cylinder-head joints require 20 foot-pounds of torque. The thermostat housing bolts to the cylinder head with 22 foot-pounds of torque. The valve cover requires 7 foot-pounds of torque to join to the cylinder head.
