I am needing a refresher on the HCU bypass. Heat won't shut off so I want to install the bypass, but I'm not sure which hose I am supposed to do this on. I am wondering if I should just put a "U" shaped pipe between the two main hoses coming into the front (the side with all the vacuum hoses). This would allow for full regular circulation while taking the HCU out of the coolant loop.
I hope that by this point you are reasonably convinced that I am lost and in dire need of assistance.
Thanks.
