Just curious as to what is a good running temp, I have recently purchased a Garmin Ecoroute HD (Basicly a Bluetooth OBDII Scanner for your garmin nuvi) and while at idle its not unusuall to see my coolant temp at or over 100 degrees C. temp gauge In dash appears normal (and does work fine).

Should I be worried? Themo Fans Kick In Around 95-97 Degrees.

after 6 years I never really worried about the coolant temp. We drove to QLD and bank the the heat and car was fine. Fan will kick on in very hot/humid days, dont worry, car knows what it has to do :)
