Whether A/C is on or off, if driving in slow traffic engine temp begins to rise and will cool down if maintain a speed of around 60. IF its a hot day 75 or above even at 60mph temp raises way above normal but not overheat. I did check to see if the coolent was pumping through the hoses and it is(if that means anything). I also notice the fans run contineously from time i start the car. A lexus tech said that the temp guage was rising because the fans are on constantly so the engine thinks it is running hot. I know the car is fly by wire. But can the overheating or temperature rising on the temp guage be due to the fan sensors being bad? (I need to just get a shop manual)
As in my other thread im changing the timing belt so while i am there i am changing the waterpump. What else should i check to resolve the overheating??
