Condition/Concern
Some customers may comment that they may smell coolant while driving or outside the truck. This could include a coolant leak under the front of the truck.
Recommendation/Instructions
Technicians should start by inspecting the radiator for signs of leaks. Normally, signs of leaks can be found where the tubes attach to the headers.
4082319
4082322
This condition may be the result of excessive thermocycles within the cooling system caused by excessive cycling of the thermostat. These excessive thermocycles within the coolant system may cause the tubes to fatigue, crack and leak at the radiator headers. To correct this condition, a new thermostat has been designed that eliminates the thermostats excessive cycling.
If this condition is found, in addition to replacing the radiator, the engine coolant thermostat housing (w/thermostat) must also be replaced. Refer to Engine Coolant Thermostat Housing Replacement in SI, which is located in the Engine Heating and Cooling section.

Hello,
I was recently informed that I have a leak in my radiator with the symptoms listed here.
I see there is a service bulletin (15829) for 5.3L and 6.2L engines. I have the 4.3L. Is the 4.3L not covered despite having the same issue?
