Explain that please. Last time I had a dash appart, the heater core is hooked directly to the cooling system without any restrictions. The temp in the cabin is controlled by doors within the climate control system.
How could I have left ANY old coolant in the system?
As far as gas mileage, the car is only in open loop until the engine warms up. I live in Florida, so that's two extra minutes of running rich (max) until the car comes out of open loop. For better performance, higher fuel mileage on a highway cruise, longer engine & oil life I'll take a two minute hit every time.
edit:
Now that I think about it, the engine warm up time is not affected by the lower temp thermostat because the freakin' thing is CLOSED when the engine is cold. It only gradually opens up when the engine has reached approximately 160 degress - which is in the operating range of the engine ECU. Nothing is adversely affected as far as I can fathom. Try again.
