I just noticed water leaking from the passenger side of the engine compartment of my 2006 dually with 42000 miles. It drips quite steadily when the engine is running. It appears to originate at the black cylinder up near the fire wall, or maybe at a fitting on the hose running into it. It doesn’t appear to have antifreeze in it. Anyone know what this is or how to fix it?
