overheat due to the engine coolant pump pulley
slipping.
Check and adjust the V-belt tension (deflection) as
follows:
1. Press the V-belt down with your thumb with a
force of approximately 22 ft-lb (98 N·m, 10
kgf/m) to check the deflection.
There are three positions to check for V-belt
tension (Figure 4, (A), (B) and (C)). You can
check the tension at whichever position is the
most accessible. The proper deflection of a used
V-belt at each position is:
Note: A “Used V-Belt” refers to a V-belt which
has been used on a running engine for
five minutes or more.
