@sooxies, one of your best indicators of cooling system problems can be observed by watching the coolant level in the overflow container.  If it is checked first thing before you drive it for the day, it should be at its lowest level.  If you check it after you just parked the truck, it should be at its highest level.  If you check the level two days from now before you start the truck and it is 20 degrees colder outside, then the coolant level will be even lower than the two days previous.  The point is, is that the coolant level will probably never be the same and that is normal.  If the coolant level remains the same when checking the level under different conditions, that is a strong indicator there is a  problem.  So, the question always is - is the coolant level at the level it should be for the current conditions?  You get the picture...

 

I hope all is well.
