What i meant by bypassing heater core was to disconnect the water flow to the heater core and plug the other hose so no water would flow through the core.water still leaked from under the car,not just dripped but poured out. When the car got hot,heard some type of sensor buzz sound from inside the car appears to come from the passenger side,faint but noticeable.Can you tell me what climate hoses you are refering to.Would like to stop the water from leaking but difficult to trace from under the hood to where the water actually leakes on the ground.Hoses dissapear into the body of the car from the battery area
