older vehicles with A/C had a factory heater bypass valve installed. Newer vehicles do not. All well and good, except for the fact that there's still heat going into the cabin of the newer vehicle.

All we're talking about is installing a valve to bypass the coolant flow through the heater core during summer months, and during warmup.

Generally, one could get about a 10 to 15 degree colder discharge temperature coming out of the A/C, with a heater bypass in place. As for warmups? I'm not entirely sure a heater bypass would provide any sort of measurable decrease in warm-up time.
