Torque cylinder head hold-down bolts.
Initial change.
Check that AC connections are secure with no chafing.
Adjust as needed. Lubricate linkage.
Adjust belt tension (3/8 - t/2 deflection).
Inspect for proper tension (3/8' to 1/2' deflection) and adjust if needed. Check belt
for slipping, cracking and wear. Adjust tension or replace as needed. Replace cover.
Check electrolyte levels. Make ~ure cables and connections are in good order. Clean
off corrosion if needed. Apply petroleum jelly to terminals for corrosion protection.
