I own a 2003 Chevrolet 2500HD, with the 6.0l engine. During the summer time I do not have many problems with it, but when the weather starts getting cold it will run for 10 to 15 mins then go into reduced power mode. I have changed out the water pump and the thermostat. What do you think is wrong with it?
have the same problem?
