QUESTION:  It sounds like you are telling me that you will not answer my question or either you don't know. You will not get my business. I thought this site was to answer questions not try to drum up business.

Answer
u do as u wish   what I do on here  I dont get paid for. U tell me how I am suppose to tell u whats wrong  and be right on the money when I am not there to see it first hand  and I am telling u to make sure the coolant is full at the radiator because I see water pumps leak all the time and cause the heat not to work due to lack of coolant. Now back to the question I asked   is the coolant full?  if yes then go onto the heater core lines  are both of them hot  same temp?
