I'm about to pull this coolant line completely and wanted to get a quick sanity check before doing it. It's the original line that is routed to the throttle body for TB heating when cold. It then exits the top of the TB and passes behind it and back down into the rear housing.

I've done the TB coolant bypass/FIC adjustment a while ago and have no issues with that - I just wanted to check with other knowledgable folks as to if removing that coolant path would be an issue. My thinking is that it will not be an issue as it appears to be for TB pre-heating only and does not represent the core of coolant flow within the engine based on the hose-sizing and exit/re-entry points. If you look at the flow-path it should be exiting the cooling system mid coolant-flow and then re-entering near the t-stat exit where heated coolant exits anyways.

 

It's nice to finally remove all the crap from under there too.

 

This coolant line has been capped at each end on my 7 for several years.

 

Thanks twok, I figured it was TB only. Just wanted to make sure.

 

U can route the coolant hose from the back of the motor to the front. Then u can cut the metal lines off the bracket to make it nicer under the manifold.
