Heater valve and hoses installation
Engine bay work must finish before paint. Therefore I installed the heater valve and hoses next. First I ran a temporary bypass hose between the Coyote heads. Builders who skip a heater often use that bypass. It closes the water circuit so the engine can run. Also, at the bottom of the photo you can see the GATES 3732 5/8″ heater hose. It joins the two water tower ports.

To set up the heater, route hoses from the engine to the HVAC unit. Then extend the hose runs and add angle connectors. Also, I added hose wrap for a cleaner look.

Parts for the heater hoses
Mounting the Thermotion valve on the firewall was my last bay task. First I used three 3/16″ pop rivets to lock the valve down. Next I lined up the hoses and trimmed them to length. After that I wrapped them in protective sleeving. Finally I clamped everything in place. Space is tight. Still, once it was done everything fit and should work.
Finished heater valve and hoses install
I am happy with how the heater valve and hoses turned out. Using every scrap of bay space was a challenge. Meanwhile I am installing the HVAC blower. However the tight space makes dropped screws a constant problem. Still, I will get through it.
