I checked heater pipes at that point that you told me in previous post it has two pipes which are connected toward interior wall.
I remembered that AC mechanic at eastern ac removed the air filter box and did some thing near the thermostat housing and also my coolant will waste in this process when he removed that pipe. But I can't find non-connected heater pipes to the engine.
Can you tell me which pipes are removed by eastern ac. They also removed that heater pipes from your car as well.???/
