Warm Up

burnsca:

Your engine is operating normally. There are 2-3 gallons (I don't recall the exact volume) of coolant that have to be heated up from ambient to >100 F before you start feeling some warm air from the vents in the winter. If you have not done it, flush your coolant system out and replace the t-stat (o-ring goes on top of the t-stat), and add a bottle or two of Water Wetter. A clean system transfers heat better.

My wife's '08 4.0 v6 Escape heats up much faster than my stang. I let the pony warm for 10 minutes on cold days and 5 minutes on warm days.

My 99 Cobra takes around 7 minutes to get from start up to the "normal tempurature" zone
