Coolant hose under the intake manifold leak - 2004 4RUNNER V6

[PTPT2002]

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.

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?

If you don’t mind me asking what size hose did you end up going with? Currently having same issue after changing water pump

Trim off 1/2” from the end and use a worm gear hose clamp. Done!

If you want to buy a new hose, buy both sizes and use the best fit. It’ll set you back all of $5 for 2’ of radiator hose.
