Strange temp problem
Yesterday when I was driving home from work I noticed my temp gauge went from about the A in normal down to cold and then back up again to the A in normal. The truck was idleing rough and after it did that it seemed to settle down and it seems to be okay now but it kind of scared me. Any ideas of what could cause the problem and should I be concerned? BTW we are in a major heat wave with temps around 37 degrees celsius and
the humidex being about 40 celsius.87 F150 2wd
4.9 Litre 285000 Km
4 Speed Transmission with overdrive.
Thanks in advance
