07 Pilot leaking coolant under intake breather tube. Not coming from hoses. Doesn't appear to be coming from the thermostat. It's just puddling below breather tube.
Can anyone help identify?

There are two hoses that carry coolant in/out of the throttle body, they're small, check there also hose coming out from under the intake manifold as there's a coolant tube that runs under the manifolds.

You could "rent" a coolant system pressure tester that attaches to the radiator and pump some air into the system and look for leaks. You get it at any of the big three auto store then return it for a full refund. Make sure it'll fit your where your radiator cap goes.
