Hi,
There is a coolant leak from this "SERVO UNI" also known as "part
0008300684" or "ACC Servo" or "Heater Control Valve". I couldn't find much information about this mysterious part but got idea that it responsible in some way for vacuum system and heating and ventilation. Price for this part is SO MUCH and my car is so old that I think I can survive without heating and ventilation. But now sometimes I have a problem with engine overheating because I think leak through this servo unit. My idea is: can I just block coolant circulation through this part by jamming its pipes? I think it will stop leak but will it create any other problem? My main concern of this solution are: will it create engine overheating? will defrosting of windshield work?Thank you for any advice
