    coolant dumping out under exhaust manifold

    coolant is still leaking out fast and furious under the passenger side exhaust manifold cover, I found a heater plug missing on the opposite side, replaced, and still a leak some where. I can grab the HCV and twist it around, it does not appear to be leaking...any ideas?

    It is most likely the HCV or maybe a hose came off.
