    Coolant leaking

    Hi all. I have a coolant leaking in the back of the engine. I replaced the heater exchange valve but that did nothing for the leak. I did take apart the water transfering unit and reinstalled it but now the leak is greater. How do i look at the back of the engine while it is running to see if i can see the leak? What can the cause be? The car is running fine other than the leak and if i am unable to fix the leak i will have to get rid of the car. Please help with any suggestions.

    The heater control valve is a common leak problem followed by the water pump. Control valve cost me a total of about $150 to replace. If that is all that is wrong with the car, if I were you, I'd get it fixed and then get rid of the car.

    Usually the front of the car, but it could possibly, but unlikely, flow to the rear of the car. I'd wager that the problems the heater control valve.
