Failure to maintain your coolant at the proper level will cause potentially serious
engine damage. The warranty does not cover engine damage due to overheating or
any other cause associated with improper coolant levels.
Because this process should be completed while the engine is cool (in order to avoid burns), it is
recommended that this check be completed prior to starting the engine. On engines with serpentine belt
systems, however, no change is necessary. Belt tension is maintained by the automatic belt tensioner.

Note: if the belt is too tight, excessive belt and bearing wear can
occur. If the belt is too loose, slippage can occur, resulting in low
alternator output and rapid belt wear.
