How to replace a leaking oil cooler - Mercedes A/B Class (w169/w245) CDI

Here we had a bad oil radiator leak. Oil went all over the engine.
With my tutorial you can easily spare 1000-1500 dollars. Mercedes requires about 1500 dollars for the job.

This is the diesel CDI OM640 engine. I used INA tensioner, Contitech belt and a MB genuine oil cooler. Please subscribe to my channel :-)

Great job Sir , I'm quite impressed by the dedication to demonstrate the execution of such complex task, having the the same problem with my A170

Also the added commentary using stills and text to describe certain points is very good. Very easy to understand. Added WIS info such as torque figures is also great 👍 Best video I’ve seen so far showing how to lower the engine. Some of the camera angle are very unique, must be a small camera - worked a treat

Great video, showing how to replace the seal on this component but also how to lower the engine. At @

Great video, I have to replace the steering rack on this model W245 and there is no room anywhere. Does the engine and subframe have to be dropped. I looked in WIS and it’s not clear and shows the A class in pics. Any ideas?
