Not in a manual. An auto would have some solenoids active in the valve body, but you are free of that scourge
Injector duty cycle may increase, but I doubt that will make much difference.
I doubt the electrical rad fan will even get a look in at this current temperature so if the AC isn't telling it to run it shouldn't come on at all. The visco fan should be more than enough.
Do you still have SAI on yours? That blower uses a bunch of amps. Maybe just pull the fuse for that, or possibly warm the engine up while still on the battery charger?
I can't think of anything else.
