Allow to EA825 4.0 in the VW-Audi Group to circulate the coolant fully from start-up. If the N649 solenoid fails your car will overheat. Also doing this mod will save the rest of your motor from a leaky coolant pump in case you get one. Possibly this might extend the life of the pump too, maybe.
Printed using TPU90. The solenoid is hard to reach, hence the side assist, insert screw, some tape, and you can slide it onto the nipple with ease. When you take the hose off put a screw into the original hose to block it off.
