Would it make any difference if I disconnect and plug the hose the comes off the "T" on the lower radiator hose? Then replace it with a hose with NO T installed......
I am tired of always having leaking problems with all the connections........
I have read it does not effect heating or cooling of engine.
Has anyone else done this?
Please advise
Thanks.

 

It depends where you are, where's Oak Creek ?
I think these are the small hoses that connect into the upper intake manifold to warm it in colder climates, if it's warm where you are all year around, then disconnecting them won't affect the over-all cooling of the engine.
As for the "T" in the lower rad hose, that should be left alone, it circulates through that until the thermostat opens.
