My neighbor pulled up next to me coming the other way and started talking about stuff while we sat at idle the other day. He took longer than I expected or I would have shut down the engine. I looked over at the Ultragage and was shocked to see the engine temp display was sitting on 212F and the cooling fans up front were NOT running.
I quickly excused myself from his conversation and turned on the A/C to get those cooling fans running. The temperature took a while to drop, but did come back to their normal, for this hot year, 186 to 195F value.
Now, as I have a temperature reading from the OBDII port on the Ultragage, the temperature sensor on the end of the engine head must be working. The fans, their control relay(s) and wiring must be connected because they come on the instant the A/C is started. Doesn't this mean it's all hooked up and working but the SOFTWARE isn't satisfied it's hot enough in a stopped, idling Smart to turn on the fans at 212F....which seems stupid?
How hot does it have to be before the computer turns on the fans with no A/C running in 102F outside air temp??
Thanks for anyone who can enlighten me. I think they should have been running before we got to 200F!
