Hello everyone and in advance a happy Christmas. Since I just have a little time I wanted to describe here a new problem of my Yaris D4D year 2002. Three days ago I was a little more brisk about 100km on the highway. Suddenly the first time ever came the message that the engine overheated. (The temperature-acting person has flashed red) I then rolled out and the display was extinguished again. I then continued with 2000 tours and the display e For me it can be: – the cooler pump – the thermostat – the fan behind the cooler. To limit the causes the following further information: The engine runs normally. The fan does not rotate, but can be turned with the finger. (=> Defect or it does not get any signal/current) I tried to turn the wedge belt (expanded). But it has to try again with more force. The interior heating gives off heat. If you guess h abt I would be happy about a hint. Ciao
