Is there another place that maybe sepcializes in auto repair help that a person can ask specific questions? I wonder if I can call the dealership and ask. I started to replace the thermostat on my 2004 Dodge ram 1500 but can't figure out the radiator drain cock. It turns 90 degrees but that's it. Also, I got to thinking maybe the waterpump is causing my problems of overheating. I'd just like to talk to someone about some problems.
