I've had my 4720 with the factory cab almost a year now and it seemed like it took a long time to warm the cab to a comfortable level. It was about 20 degrees last night and it was nearly 20 minutes before I had reasonably warm air coming from the heat ducts.
Last winter it was much colder and the warm up time seemed much faster. I don't know if it might be a problem with the thermostat because the coolant temp guage seemed to take forever to move and it never got beyond about a third of the way into the normal range.
I just had the factory radio/CD player replaced and the roof has to be removed so I was thinking it might be the famous sealing issue that has been discussed here before.
Just curious, for those of you with the 4000 cab tractors where does your temp guage run say after about 15 minutes? Under normal conditions mine runs just a tad over the half way point on the guage. It was well under that last night and I was operating for about 45 minutes so I'm thinking its a thermostat issue.
