Hi, I can't figure out where the coolant line under the throttle body on a 3vze goes. If anybody knows, please help.
Thanks.

 

Will double check in a bit, but I'm pretty sure you need part number 16282-65010 which is the small coolant hose that runs from the throttle body to the lower intake plenum. That barb you see goes to the IAC valve in the throttle body. See attached.



I actually just replaced this hose on my 3VZ truck a couple months ago as the old one was falling apart when I removed the TB to replace the TPS.
