I installed this in my E46 320i, and I found the process to be quite easy. I was extremely happy with the price and believe it to be an OEM part due to the ease of installation. You may need to adjust it a bit during the process. I have small hands, so I didn’t have to remove the fan clutch, but if your hands are larger, I recommend removing it for easier access. Additionally, I suggest purchasing a new coolant temperature sensor, as reusing the old one is likely to result in leaks. Overall, I found the installation to be straightforward.
I selected this item as I need to get my vehicle back from my garage and back on the road for my job and it’s been a long time since I’ve found the correct part too.
