Shane Posted January 18, 2009 Share Posted January 18, 2009 I had a similar prob afew months back. Mine was smokin. Replaced thermostat, battery & altenator(it needed that). Still when I cut it off I noticed a hissing sound. Alot of people said that it may be a cracked head gasket. I replaced the coolant jug and the coolant jug lid and the hissing stopped. Sometimes since the coolant system is pressurized and these trucks are 20 + years old these things happen. My advice start with the cheapest fix and go from there. Atleast then you have alot of new parts that in time would have need to be replaced. Link to comment Share on other sites More sharing options...
