Q: Car heat is cold until I add water and over heating with out telling me

Hello, thank you for writing in. There seems to be an issue that we need to take on first and foremost. This is the fact that you are having to add coolant to the system. This means the coolant is leaking either externally (onto the hot engine), or internally (being consumed with the air/fuel mixture). The best way to tell is to simply run the vehicle and watch for the leak. If the engine is consuming the coolant, you are likely seeing white smoke from the exhaust. This is most commonly resolved by replacing the head gasket. Common components to look for an external leak with are the thermostat and the water pump. Both would cause the symptoms you are explaining. Fore more help with the issue, contact our service department to schedule an appointment.

If you believe your water pump is leaking, I would recommend checking this before anything else. If your heater is not getting hot this is because your coolant level is dropping. Replacement of the leaking water pump should resolve this issue. I would recommend a Fluid leak inspection to determine where the coolant is leaking from. Once the source of the coolant leak has been found replace the leaking part and this issue should be resolved. Consider your mechanic for your water pump replacement as this can be done from your home or office.
