Ever since, when you drive at freeway speeds for 20 minutes or more, the temperature gauge drops to almost the C (cold). It then sometimes raises slowly to a normal reading, in the middle. The thermostat was replaced once with the head gasket, and again approx 1 month later with no improvement. What could be causing this? Should I try a toyota brand thermostat? Is the temperature sender faulty? The heater seems to blow colder when the gauge reads low. Thanks[/color]
have the same problem?
