Condition
Some owners may experience high temperature gauge readings.
Cause
Insufficient coolant flow from the left leg of the water pump.
Correction
To eliminate all other areas that may be suspect (such as coolant temperature sensors. gauge clusters, and electrical circuits, etc.) perform all diagnostics
listed in the Service Manual. To aid in diagnostics, technicians may want to use instrument panel gauge testers such as Kent-Moore J-33431-C or
J-24538-B. If the overheat condition persists, install a new water pump which optimizes coolant flow from both water pump legs.
