Since I have my C20NE in the Corsa there are a few problems. Even though: 1. What can it be that my NE is already operating hot after 2KM driving ? Already shortly after starting the fan radiates extremely heat. Have then 95° operating temperature which can also be held. In the stand it goes up to 100° until the fan goes on. Thermostat is 100% in order because the cooler is bang “hot”. 2. He dies as soon as I have driven longer sometimes in idle mode and is then only with gas 3. Now I hear a strong knock on the area of the 2nd cylinder. From below you can hear that very well. What could that be, conrod bearing damage? But from the head that does not come. If the engine is warm, the knocking is gone. What consequences can a damage to the conrod bearing have? Bzw. what ads are there then? Here is a video where you can hear the knocking at the beginning.
