A coolant leak may develop from the radiator. Ford has released and updated radiator and powertrain control module (PCM) software update to address this issue. The software update includes revised cooling fan operating parameters. Failure to complete both service procedures may result in repeated radiator failures.Google+

Average Mileage: 77,870 mi (20,000 mi - 135,000 mi)
2007 sport trac temp gage light goes on, truck slows down, transmission does not change gear and sounds like the fan is running loudly.The truck does not want to speed up when this happens. I park to the side of the road and let it sit for a few seconds and it will go back to normal. Has happened every morning for two weeks. Changed Thermostat but no change so far.
Also leaking power steering fluid from somewhere but cannot find the reason. Everything is clean and nothing looks torn.

radiator leak (third one in 2.5 years), had it "reprogrammed" but it happened again. Does it need to be "reprogrammed" again??????

Same overheating and radiator leak problems reported by others. I have already gone thru 4 radiators in this truck and it only has 65,000 miles: the original factory-installed radiator, plus three replacements over time (all of which I had to pay). It seems that the radiators only hold up for ~ 15,000 miles. The cooling system on this truck is a BUST!
The plastic housing cracked, had to have it replaced.

Exact same problem as stated by Rookie. Sound like the engine is running really loud and started overheating by leaking fluid from the radiator cover next to lower radiator hose connector and side cover.

Radiator leak causing overheating. I thought it was leaking from lower hose and replaced hose. Antifreeze now streaming into bucket under loer hose outlet. It looks like the leak is hidden by the plaastic sid cover.

My truck just died on me, would crank but not turn over, no alerts to truck overheating, mechanic tells me it looks like it has been run hot! I service my truck religiously!
