Does anyone know what this cap/ port is called? Its leaking what appears to be ATF fluid or coolant?. It's below the exhaust manifold next to the oil filter. Thanks!

My guess was coolant because of the location? But it also seems thicker/oily, like ATF to the touch? Strange...

red in color is usually either trans fluid or coolant. In either case u definitely want to attend to it right away especially if its coolant as losing too much of that equals overheating.

as long as its cool to the touch like in the morning; I would take the radiator cap off and fill it with coolant. Same with the overflow tank; but u again u definitely want to get that leak fixed asap.

just make sure the rtv u use is made specifically for high temps; otherwise it may not last that long.

At your mileage, may as well do a complete coolant drain and fill, make your coolant mess at the radiator drain plug and block drain plugs. BTW, Toyota SM specs a different FIPG (Form In Place Gasket, aka RTV) for coolant contact as compared to oil contact, but seems people use the oil one everywhere without problems.
