i have a ST4 which shows around 177 on the temp gauge for normal running as soon as i hit any traffic in goes up to 195 sometimes 200, could someone tell me the normal running temperature for highway and then city. when the gauge touched 200 i expected the fan to come on it didn't, also at what temperature would the rad fan normally come on.

fan(s) on at 207

Hey, my ST3 runs at 76 c on the highway and never above 103 c in town. The fan starts at 102 c and shuts down at 98 c. hope this helps

Coolant problems? What coolant problems??

My Duc 2003 ss 1000 ds has read 294 (F) stuck on QE pl (queen lizzie parking lot). I have been told that is not too far off normal

The highest oil temperature reading I've seen is 125 C (257 F) in stop-and-go traffic on a 30 C day.

When the oil temperature hits 160 C (320 F) the high temperature warning light is supposed to light up.

So watch out if you ever get caught in a traffic jam in the Sahara/Gobi Desert/Death Valley on a hot summer day.
