156 2.5 V6 water temperature & startup problem....
I've just replace the water pump, new CAM belt....etc
After the replacement, when engine is idle, the water temperature raise up to 100, but when the car is moving or even stop the car and press on the throttle, the temperature will drop back to 90, if the car goes on the highway, it will even drop to under 90......I have already tried to relpace the thermostat, still no good.....any ideas....?
And problem, when I have parked the car overnight, or over a long period of time, the car won't start unless I press the fuel cut off switch....But if the car was not stopped too long, I can start the car without pressing the fuel cut off switch.....Is it some kind of sensor failure?
