How long does it take to go into the red with the A/C off? What kind of driving are you talking about with the A/C off when it goes into the red? Or will that happen just sitting idling with the A/C off?
This may sound like a dumb question, but when the "temp guage" goes towards the red zone.....is the engine actually getting hot? Can you keep your hand on the intake without burning your hand.
A bad "coolant temp sensor" can cause the temp guage to do weird ****, but it doesn't mean the coolant is actually getting hot.
Or...if the temp sensor is bad it can actually get hot and it won't turn the fans on.....and then a cycle starts where the t-stat can't keep up and will slowly start to NOT close fully, then it will stay full open...then you will over heat.
