I know this sounds crazy but at idle... i'm hearing a running water sound.. its coming from behind the dash next to the pasengers feet. I know that sounds crazy but i can hear it as clear as day when i put my head down there. it increases in sound as the motor is revved. I also hear a hum from what sounds to be an electric motor coming from the same area.. It is a very clear running water sound... is it posibly part of the heating system... and is there any way to make it quieter? Is my car going to flood? Any help is GREATLY appreciated

Thank you

Sounds like the heater...Normal.

You have air in the cooling system. Turn heater on full and bleed the system. This may have to be done 5 or 6 times.

Agree, that is air in the cooling system and I bet you started to notice it right after turning on the heater.

Tom's directions are correct. Leave the heater on and bleed the system.
