throttle body coolant hose question
Hi all!
When cleaning the throttle body plates today on my 92 LT1 & I noticed previous owner had already re-routed the throttle body coolant line (which I was planning to do).
Looked carefully in the FSM at the drawings & my question in there is the hose connection on bottom right (4 o'clock position) but where did the coolant circulate to? FSM showed only one connection point for coolant at throttle body? If that was the inlet where was the outlet or was there not one? I assume there was not one or...?
The "T" connection where the hose to the throttle body was was routed w/ a long hose piece up under coolant reservoir & am taking that off tomorrow for a good cleaning during the flush process so I can see where that went to then.
Thanks in advance for the help!

i am planning on just removing the whole throttle body coolant hoses at their t-sources, as OP suggested. questions:
1. will i have to drain all my coolant to do it? or:
2. can i just pull off the TB hoses, drain whats in them, cap the T junctions they came off, and bleed the coolant system where the little brass thing is on the water pump?
3. do i need to cap the holes in the TB where the hoses were connected?
thank you!

What does running coolant to the TB do anyway. Mine is disconnected, but it has an irratic idle. Idles and 550 but will jump up and down up to 1200 when sitting at stoplights. ??? Help
