But all gauges were normal.
Oh and this...
Lot of vehicles these days have dumb gauges that appear steady but reality is they just don't move from either one position (Ford oil pressure), or they have a huge dead spot around normal range (Ford coolant temperature). Note I'm singling out Ford, but there are others.
That's why I installed a scan gauge in my 03 Ford Class B for the first time I took it through the western mountains. Dash gauges never moved. Scan gauge told a different story. As I understand it the stock coolant temp gauge on my Ford won't move up until you are on the verge of overheating.
