It will eventually, but its sort of normal to stay cold on shorter journeys. The stat stays closed until the engine gets to 90c, then it opens a small amount and starts bleeding water thru. The water in the rad is so cold that it will typically only let by at a very slow rate, and thus take a long time to get to the point that its heated the entire radiator up.

If you have climate control you can view the engine coolant temp on there, so long as its sitting at a sensible temperature it'll be fine.
