Cooling gremlins

Noticed the other day while out for a drive that my temp gauge was reading lower than usual. As I continued to drive it would creep back up to normal operating temp then drop back down again.

my best guess is a stuck thermostat, would I be correct in that assumption?

A sticking thermostat would seem like a good bet, so a replacement thermostat (195 deg, non-failsafe) would be the first thing I would try.

Edit...I see you're in Canada...do they refer to them as 90 degC thermostats?

I honestly don't know if they do or not It's still somewhat blended with our use of metric and imperial up here still.

But that will be my first thing to replace before i check other systems. the radiator is only three years old and its never leaked a drop since i bought it.
