Some vehicles described above may exhibit a condition where temperature gauge readings fluctuate in the normal range. These gauge fluctuations may
be as much as 1/4 of the scale, however, the indicator should never enter the red high temperature warning area of the gauge under normal operating
conditions.
Coolant temperature sensor location combined with the thermostat cycling characteristics contribute to this sensitivity. The condition is considered a
normal characteristic of this engine and should not be cause for instrument panel cluster, gauge, indicator sender, or engine coolant thermostat
replacement or alteration.
