If your "normal" driving is leisurely like mine is, it may never fully open. Unless you are driving uphill. Or accelerate rapidly. Basically anything that calls for more power makes more heat which makes the thermostat open more.

Many people think these things go from closed to open and just stay that way. And that isn't necessarily true. I've watched the thermostat on a stock type-1 engine on the dyno opening during a power pull, then closing a bit between pulls. It's a regulator.
