Actros overheating we are changing the internal combustion engine mp1 to mp2 

Hi, everybody
Mercedes Actros came to us for repairs. The reason for the appeal is to warm up the engine. at first glance, it was clear that the water pump was to blame for this, which was silenced by removing the tubes from the moderator!
The owner also asked me to take a look at the cylinders!
In this video, we will analyze this engine and identify its malfunctions!
then we will install another internal combustion engine and start it!
Thank you all for watching!
