Throttle body coolant flow direction - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

I searched around and could not find an answer other than "it doesn't matter". But I'm curious, for the two coolant ports at the front of the TB, does coolant come out the top or the bottom outlet?

I have no idea, but if you undo the hose, pull the fuel pump fuse, and turn the car over, the end spewing water out will tell you where the inlet is.

Thanks for the idea! I can now confirm that the bottom port is the where the coolant comes out.
