I give up! I have flushed and filled the cooling system, put in a new thermostat, new radiator cap, and replaced the water pump (the old one was leaking under the timing belt cover) and STILL the engine does not get to operating temperature! I can't figure this one out.
Maybe I went a little heavy with the AF? I mixed about 60-40 since this is going to be primarily a winter car, but even with putting a piece of cardboard in front of the radiator it does not get up to temp unless idling for 7-10 minutes, and even then as soon as the car starts moving the gauge drops to cold.
Any ideas?
