I need some advise please. Recently this happens. During warm up and idling in the yard, the coolant temp indicator points straight down or back if you will. It fluctuates a little overand under the temp symbol. However when riding the needle points to the second marker on the gauge.Isnt that too cool for the engine? The fan turns on and off as normal, the coolant reservoir is full and I can see the coolant when I remove the filler cap when the engine is Cold. I have searched and seen many post about overheating, but not this. The temperature here now is around 15C(59F) and 17c(63F) When it was around 25C (77F) the temp gauge behaved "normal" Is it something to worry about at all?
