upper hose very hot, lower hose very cold, no overheating


Recommended Posts

hi all,

i have 2007 tahoe 5.3 4x4 automatic.

everything was doing great until three weeks ago my truck start loosing water from the radiator.

troubleshooting done and found that waterpump seal was leaking. so water pump was replaced

after few days i noticed that the upper hose is very hot and lower hose is very cold,

i thought its tstat, replaced tstat , still same situation

car is not over heating, the gauge stays around 85 degrees,

now the only chance is that either water pump is not working or radiator is blocked?

kindly help

Upper hose should be hot and lower hose should be colder than the upper. Your temp sounds about right. With no overheating I wouldn't be worried. Just make sure you have no trapped air in the system
