    Hello,
    Would anyone be able to help me identify which part I need to replace to repair the coolant leak on my 2005 V6 4Runner? It is coming from a brass line fitting that is under the airbox on the front side of the engine and looks to be going to the intake manifold. Here are a couple pics. Thanks very much in advance.

    I, for one, can't see the leak in these photos. Maybe you could get some better pics or draw an arrow/circle the specific areas? Hopefully that will spur a better response for you! Is the air box easy to remove in order to get better access for photos?

    Kind of hard to see where we are in the pictures... Pretty sure the plastic thing in the immediate field of view is your radiator fan shroud? Leak there is annoying but reasonable. Just looks like engine coolant from one of the small lines around your water pump/thermostat housing. Id be willing to bet the hose clamp is not doing its job or missing. Or you can do a quick ebay search for 1GR-FE coolant hoses and buy new. :cheers:
