Since purchasing the car in Feb., I have replaced the front rotors and pads and the rear shocks. This weekend I am tackling the full cooling system refresh. I have done this on my E36 M3, but have no experience with the E46. Anything special I should look out for? Everything looks packed in there pretty tight, but I would imagine it is pretty straight forward. BTW, I am using the Stage 3 kit from ECS. Any comments or tips would be helpful. Thank you.

Yes. Very straight forward. You'll have no problems with the exception of the expansion tank, hoses, bleed and temp sensor

Seriously though. There are good DIY's on this site to get the expansion tank out.
You'll have to muscle the hoses off. Make sure the steel slide clips are fully undone (remove them if you have to).
Read up on the bleeding procedure.
How do you plan to drain? From the expansion tank or the block? Both? Are you going to flush?
Just food for thought.

Use your biggest hammer to get that expansion tank off! Or just take out the entire mount and disassemble outside the vehicle. But that isn't any fun

IndvdlM: It looks packed in tight but once you remove the electric fan (MT) or mechanical fan and shroud (AT) and the serpentine belt, and take off the plastic undertray, then there's lots of room to work.

Go to the hardware store and buy two 10mm bolts that are relatively long and have a pitch of 1.00. Use them to remove the water pump. There are two threaded holes that don't have anything in them. That will push the WP away from the block. it's simple and easy and you won't puncture your Radiator when the pump comes flying off because you used a pickle fork on it...

On the E36 you just reused the bolts that held the WP in place. Is that not the case with the E46?
