Hot or Cold
Hot or Cold
(OP)
I am about 1.5 miles from the main drag when I leave my house on these cold winter mornings. Will my truck F150 heat up faster if I drive 30 mph (the speed limit) or 60 mph. (Illegal) But at 60 I will get there twice as fast.
Just wondering which scenario will get my heater working faster??

Most of my 1975-1996 Volvos show some temp on the gage and have started to blow warm-ish air at the mile marker even when sitting outside all night < 32 F.

Mike - my sympathies if your engine is the aluminum-block 4.6L V8.
I'd start my car, set the seat heater and defrosters on (fan speed high) and go back in the house to do the last few things - brush teeth, put weather-appropriate jacket on, grab lunch and other stuff, kiss wife goodbye.
Usually by then the windshield would have become mostly clear and the wipers could take care of the rest. But it would still take over a mile at 25 - 40-ish mph for the coolant temperature needle just to struggle off the cold peg.

This reminds me of a neighbor whose warmup procedure was to start it up cold and rev it to about 5,000rpm repeatedly for about 5 minutes. Good engine, for a while.
