Honda Accord/Civic/Prelude 1973-1983 Repair Guide



Aluminum has become extremely popular for use in engines, due to its low weight. Observe the following precautions when handling aluminum parts:

Never hot tank aluminum parts (the caustic hot-tank solution will eat the aluminum).
Remove all aluminum parts (identification tag, etc.) from engine pats prior to hot-tanking.
Always coat threads lightly with engine oil or anti-seize compounds before installation, to prevent seizure.
Never over-torque bolts or spark plugs, especially in aluminum threads.

Stripped threads in any component can be repaired using any of several commercial repair kits (Heli-Coil®, Microdot®, Keenserts®, etc.).

When assembling the engine, any parts that will be in frictional contact must be prelubed to provide lubrication at initial start-up. Any product specifically formulated for this purpose can be used but engine oil is not recommended as a prelube.

When semi-permanent (locked, but removable) installation of bolts or nuts is desired, threads should be cleaned and coated with Loctite® or other similar, commercial non-hardening sealant.
