Can't go 100% by the gauge. But should be below the 200 mark. Unless you are in hot weather and sitting still. My fans are set to kick on at like 178-185. I also have a 180* drilled thermostat. But you are in Canada, so I wouldn't worry too much of hot weather. But if your gauge is hitting 200 alot or higher, start checking out your coolant system.

stock thermostat is 195, I believe fans are set to turn on about 210, or if the A\C is on. I personally run a 195 Tstat Oct-Apr and a 180 May-Sep. I also cover 1/2 my radiator with cardboard when the temps dip below 30 degrees or so. The car heats up much faster, which equates to better MPG. My issue is that I leave work at 1am, and almost immediately drive 45mpg for 5 miles, then 65 for 10 miles, then 45 for 2 miles and then I am home. I may hit 1 or 2 very quick stop lights. Without the cardboard, my car does not reach full temp until I am over 1/2 way home. With it, I am at full temp when I reach the highway, 5 miles sooner.

i was going to do that this winter but i never had time to get the cardbord because i only drive maybe 10miles to work every day and when it was cold i would just get to work and my heat would start to get warm
