If I plan on doing the TB bypass with my new TB, do I need to transfer the old bottom piece with the coolant tubes attached? It has a sensor on it, so I'm thinking I will have to, but I wanted to make sure.
Thanks

 

Remove the hose from the TB that comes from the radiator and connect it direct to the cross-over metal tube on the passengers side valve cover. You need to maintain that coolant flow. That is the most simple and easy TB bypass.

The IAC is on that so yes.
