Re: Possible Hose?
The empty ports were used to warm the TB in cold weather by running coolant through them in other applications.
Problem is that it runs hot coolant through the TB even in teh summer time.
You will see a lot of the LT1/LS1 TB guys referring to a TB coolant bypass, those are the ports that get bypassed. GM jsut did it in advance for us SyTys.
Funny story.
I failed my EPA roller dyno emissions and the dip$hit at the facility told me I had to have those ports connected to pass my visual even if they weren't used from the factory.
They hire any moron at those places.
