Looking fore every little bit of power and thought that by removing it might help cool the intake. the car is a 1996 crown vic 4.6
The intake is plastic and not heated. If the heater core is sound and doesn't have leaks you might want to just leave it in place for the cold weather...
On the rear of the water pump is a pressed in metal hose that is the return from the heater core. These do often rust. If you have the motor out I'd suggest blocking it off. Same goes for the heater water outlet on the right rear head, use a freeze plug there.
Do NOT run without a thermostat, it is needed to block the bypass or you will overheat.
