The question is the outlet radiator hose from the engine to the radiator never gets HOTTT.

The upper inlet radiator hose is HOTTTT. And it, the upper hose, expands a bit when the vehicle has been driven.

What could be the cause of this?

Radiator? Cap? Thermostate? Leak?

Any help would be appreciated.

 

the thremo might be stuck closed. whens the last time you changed it?

 

Piece of shit is BRAND. Just installed it five months ago.

Pardon my French.
