[QUOTE="Andrew Homar, post: 1040178, member: 65202"] I am the original owner of a 2004 XLT. Before you go crazy check the basics. I had the same problem about a year ago. I actually got a "check engine" light throwing a code P0128 indicating "Coolant Temp. Below Spec." I replaced the thermostat along with the upper and lower thermostat housings (this is a sixteen year old truck, the housings can get pitted with age and are not that expensive to replace), replaced the housing O-ring, the temperature gauge sensor and refilled the coolant system with new G05 Zerex coolant (proper coolant to water ratio) all of which cleared the code and returned the truck to putting out proper heat in the cab. I am in New York and it can get cold here in the winter too. Cab temperature has been fine ever since. [/QUOTE]
