ok before i go on i will say that my water pump is GOOD and the thermostat is GOOD. (tested in a pan of hot water with a thermometer and opened at 170*). now, when the car is running and is at temperature, it will cause the radiator hoses to expand and when the car is driving or stopped and is given gas, the temperature gauge will fall to below normal temp and when driving it will drop to C. can someone help me with this? there is no air in the system. has been redone several times....
