94 Tbird, 107000 miles, 4.6L engine. Normally will stay dead center in the temp guage but on any uphill, will begin heating up rapidly. It got hot enough today to trip the " check guages" warning light, first time for that. Turning off AC does not help. Coolant was checked recently during an oil change and showed to be still in good shape. However, idling, even today in 115 degree heat, the temp guage stays pretty stable right in the middle. Only moves while driving.
