Many fail and owner's do not even realize that they are not functioning.

Could this be another reason for owners seeing higher engine temps in some of these cars?
Also, if the coolant has a shorter path it is not cooling down as much as it should before it heads to the block to warm up again (more)....the longer system with the hoses and heater core would allow the coolant to cool down more and have a lower temp reading than the shortened system.
Or is it possible that I am over thinking the issue?
