I'm done with the repair, and grateful for the information you all put up here. I'm typically lurking on the nam3forum as an E46 addict...so I appreciate the effort it takes to run a forum like this.

I concur with what's in this thread:

1) if your heat stops working, check your coolant expansion tank. If it is empty, then it's probably not because the engine/head gasket is a problem
2) confirm where the leak is coming from, If it is this thing, it can be easily observed after removing the plastic/fiber cover under the engine.
3) I agree, there is no need to remove the fan shroud. Removing the intake, the electric water pump, and getting the hoses out of the way is sufficient.
4) Tools: If you're going to leave the fan in, you will need a flex head ratchet for the lower bolt on the oil cooler assembly.
5) Other parts: just like knightarmor recommended - replace that stubby connector. It is nice to have a 1/4" drive with flex joint and extensions to do this.

Yeah, I was asking my friend mechanic about the aluminum type. But it’s a Friday evening and he can order OEM parts Saturday morning and fixed everything back before lunch. So, didn’t get the time to search and I’m glad if it can last another 60k KM ?
