I have a 2004 V6 4runner SR5 with about 200k miles now. I noticed recently that one of the small hoses is leaking a bit of coolant (see attached picture). It is leaking from the one under the throttle body.
Browse a bit and found GGeezer's video that shows how to remove the throttle body to get to the the 2 coolant hoses.
How to replace Coolant By-Pass Hoses
Do you know what size of a hose i need in this application? The local Autozone carries both 5/16" and 3/8" transmission coolant hoses but i am unsure which one to use. Would i be better off getting OEM since these hoses since the hoses seem to have a slight curve to get to the throttle body?
