Best starting vehicle I had while living in Frisco was a ‘57 Ford half ton with the 272 V8 with unknown mileage. I remember -40 and -44 degree mornings and using the same starting method that worked in summer, two pumps on the gas pedal and it would fire right up. Don’t remember it having a choke but it might have. Great old truck.-25º... you front rangers are so soft, not that its cold down here either. But when living in Frisco -25º was a warm morning in January. I never changed my coolant for cold weather. We did plug in the turbo Outback at night as it hated cold starts like that. All the normally aspirated stuff started fine.
