Re: Lower radiator hose does not get warm
When you say the upper hose gets hot, how hot is "hot"?
When the truck's up to temp, you shouldn't be able to keep your hand on the upper hose for more than a second or two...that's HOT.
If, in that condition, the lower hose is cool, then your radiator is doing it's job.
If you loosen/remove the lower hose (at the radiator), does the coolant drain? If so, then it should all be good...
