A few weeks ago I changed my engine belt and noticed a a gurgling sound coming from the center of the dash slightly below the climate control unit. This noise happens when the truck is started cold and initially driven after the usual warm up period (about two minutes). When I accelerate I hear the noise for a brief second or two and then it goes away. This only happens after initial start up or after the truck has been run and may have been idiling for a few minutes. This has not effected the heating or cooling ability of the climate control. Could there be an air lock in the system somehow causing this? Is it a fluid system which air passes over to generate heat? Hmmmm...... :confused On a lighter note I just came back from opening weekend at Sugarloaf. Figured me and the truck needed to hit some less urban roads than Jersey City and scince I work out of No. Reading, Mass and the better half was in Florida I could escape for some pre-thanksgiving turns. Found a great bunk house in Stratton-Eustis for twenty bucks a night with free longdistance, internet, and laundry. Ahh the simple life.
