It is such a pain they should make them out of something indestructible imo. When the AC evaporator went on the S4 I had them replace the heater core while in there just to never have to go through it again.
Thats a good question,I never had any problems with the pressure increase affecting the cooling system.I guess it could be problem if any of the hoses or seals were already weak.But I have only done this as temp fix to a daily driver and on a weekender that was setup more towards light to light racing.
