I've noticed over the last 2 winters with my '09 HCH that it does not like to make heat. It takes 10-15 minutes of highway driving before the car starts to make noticeable heat at all, and longer to reach normal operating temp on the gauge. It also loses heat quickly. Auto stop won't work for me below about -5c, and just sitting for a minute at a light will drop the temp gauge from just below half to less than 1/4 of the way up the gauge. Last night I drove for 30 minutes in the city, and never got more than 5 notches lit up on the gauge. Coasting down a 1/2 mile hill dropped it back to nothing. It was only -9c. Normally I'd suspect thermostat, but the rad hoses don't seem to be pressurized when the car is below operating temp (and running) as would normally be the sign of an open stat. So I was wondering if this behaviour was normal or if I should replace the thermostat anyway.
