e91Coolant System Replacement- Looking for some help on getting a parts list together

dakine_surf · 02-09-2024, 04:29 PM

As the title states it's time to do a full coolant system overhaul.

I was getting a low coolant light (the orange one that looks like a half-full radiator) once a month or two. More recently after driving, I would park to come out and the wagon had "Wet" itself with 10-20 oz of coolant on the ground, I topped it off and it held for a few more days until last night (I don't drive the car often) I went out to go take it for a spin since its been sitting for at least a week, turned it on and got the warning light, topped it off, drove it to dinner and home (5 miles) and this AM went to my office (11miles away) only to get the warning light as I pulled off the freeway.

Car is a 2007 (09/06) E91 N52 AT (GM unit) with 153K now, it got a new WP and OFHG around 80K so it's probably due. I'd rather buy everything and return anything not needed, but I'm having a hard time getting a list of all the parts I could **Potentially** need.

FCP Euro used to have a full kit including a new radiator but not seeing it anymore. I don't mind buying the parts individually but looking through the parts diagram was making my head spin, I know a lot of y'all have done this a handful of times.

Does anyone have a quick and dirty parts list that will cover my ass so I can get the job done, As I stated I don't mind over-ordering and sending back anything I don't use, but would rather have every part at my fingertips before I go tearing it apart.

Plan on doing it all while you're there. From this diagram https://www.realoem.com/bmw/enUS/sho...diagId=17_0351

Get 1, 2, 7, 10. Also Maybe an expansion tank and cap, and very probably a radiator. I like Nissens, Behr has been problematic. Hose #1 will very likely crack the top of the radiator when you try pulling it off. Also Mickey Mouse flange with aluminum end piece.

Bonus points if you want to do the heater lines, but I have ignored those so far and been okay.
