Ford products must survive rigorous testing for both cold & hot weather operations. For hot weather they get a brutal workout at the Arizona Proving Grounds in Wittmann, AZ. It was 112 degrees there this week. Not quite as warm as Death Valley but definitely in the neighborhood.

The Ford can handle heat with no problems.

We just traveled across Needles area and temps were 113 and the temp needle stayed in the middle.

Keep in mind that the gauges on Ford's not true "gauges". Their readings quickly rise to the mid point of the display and regardless of the actual temperature will remain in the middle. Once the temp gets extremely high the gauge will suddenly jump up into the red with little if any warning. For all intents and purposes they are not much more than so called "idiot" lights.

Coolant temperature is of the four displays I always have up on my Scan Gauge. The ability to see the actual temp displayed digitally is priceless. I live in Tucson and so see lots of temperature extremes. Even when the coolant temps reach 224 (which a 12 mile 6 to 8% grade will easily generate when the outside temp is 112 or more), the dash gauge is still reading right in the middle.

If you think those dash gauges are giving you an accurate reading think again. I cannot recommend a Scan Gauge highly enough. Another display I always use is transmission fluid temperature which can be a real eye opener and will tell you when to engage Tow Haul, locking up the torque converter and generating more efficient cooling of the transmission. Even on a seemingly slight grade this can easily result in a 10 degree drop in the trans fluid temp.

The V-10 loves to work and can handle higher temps than many realize but knowing what those temps are is crucial and that information will not be accurately found on the dash displays.
