First thing is to determine if the gauge is telling the truth, or is it that @#$@#$ temp comp board?

If the yellow wire connected to the temp sender on the engine is grounded, the gauge should read full hot. See if that happens.

When the "almost red" situation occurs again, try to get out and pop the hood and see if the engine really seems that hot. Any coolant loss?

My next step would be to jump the temp comp board. If the "Almost red" happenings still happen, then it's time to check things like the fan clutch, or flush clean the engine or clear any obstructions to air flow through the rad and a/c condenser. Or, worst case, check for a head gasket problem.

Good Luck,

Bob
