Hi, great video straight to the point, a question thought, does the system need to be bled afterwards?

[@PetersGarage111]

@@rokasnavickas6062 Thanks for the good comment. Yes you have to bleed the system afterwards. Although there is little coolant coming out when you remove the sensor, that the engine will selfbleed most of the time. But the system needs to be bled.

Hi, my cooling fan is running all the time when starting the car, could this be the problem? Bmw e90 320d 2008 model

[@PetersGarage111]

@@M4LIFE10 yes in my case the temp sensor was the problem. Check on live data what temperature is showing this sensor. If its showing very high temperature when he car is cold, that means that the temp sensor is the problem
