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.
I hooked up a scan gage to my 2005 F-250 and the readings really surprised me. My factory temperature gage is running around the middle of the gage, but the scan gage tells me the coolant temperature is at 220 degrees and the oil temp is around 250.
