Replacing Coolant Hoses
My truck is now 5 years old so as a preventative measure I am replacing all hoses that carry coolant. I have the 4.7L. There is a small hose that runs to the throtle body and then a U shaped hose that runs from the top to bottom of the TB. Does anyone know if both these hoses are for coolant? I can't find the U shaped one on the parts list I am using.
