Awesome job and thanks for sharing this great information. The only thing I might question is the turning of the HVAC temperature control **** in the cab to hot. On older vehicles, this used to allow coolant to flow into the heater core - which you want to do.

Correct me if I'm wrong, but don't many of the newer vehicles used a blend door on the air side of the HVAC system to regulate heat instead of a liquid valve on the coolant side? That would say you're getting coolant flow through the heater core all of the time - regardless of the ****'s position. In either case, it's not going to hurt you though. Thanks for sharing!

 

Great work, lovely interaction... any comments on the choice of Amsoil coolant? I've used their oils and lubes for years but JUST started to consider their coolant in my F-150 '97.
190K on the engine and going well so far... Anyone else use Amsoil antifreeze? Thanks.
