In this video I show you how to replace the radiator on your BMW E90 3 series. You can use this guide for the E91, E92 and E93 as well.
I am working on my 2008 335i equipped with the N54 motor and an automatic transmission. It will be a little easier if you have a manual transmission equipped 335i. The procedure will be very similar for all models even the non turbo variants like the 328i or 330i etc.
This jobs will take you about 2.5 to 3 hours from start to finish. It’s not very hard just a bit tedious.
If you would like to purchase a decent radiator for your 335i you can get that here (affiliate):

Another awesome video, just a reminder for people to leave the door open when you initiate the procedure because if you close the door and initiate the bleed and then open the door it will reset and stop the procedure, so then you are stuck in the car for about 10 minutes. After bleed is complete, run defroster to allow for full circulation of the coolant system. Then let cool down and recheck coolant level.
What are the 2 plugs (short and long) for? I know what they are for… auto and stick shift, But do the new radiators have plugs in them already?
Very informative, thanks for showing the bleed procedure. Also good volume on the music, does not drown you out like a lot of other videos.
Thanks for the video. I am so glad I have a manual. It made the process easier
Just ordered mine thru your link! Thanks for the video
You're acting like you didnt spend the full day trying to take off the upper and lower radiator hoses. Gtfo lmfao
Why does my radiator have a sensor on it?
Am I safe to use zerex g05? Or do I have to use g48? Thanks.
That's where mine cracked too, right along what looks like the injection mold seam. JB weld held out for a week until the parts arrived.
If anyone is wanting to do this for their 335i with a N55 motor, rejoice because this video will work perfectly.
THANK YOU, VEHICULAR DIY. Saved my Bimmer and my wallet.
When you did the DIY on the new radiator replacement, did you replace the old O-rings in the old hoses, at the 4 connection points on the new radiator?
Did you use the green or black drain plug?
I might be doing this friday, still not sure if it's the radiator or that oil cooler line connection. I broke my upper radiator hose reservoir outlet, so we'll see, but this looks pretty easy. Been a pleasure watching your vids, saved me loads of time! I think I got my misfire fixed (bad injector), but I only got to go for one ride before I tore it apart for the coolant leak. I can see why you like these cars, it's been a lot of fun this past week.
你好，我的水箱放水螺丝坏了但是不知道怎么拆除，能不能发个详细视频，我的是蓝色和黑色的塑料螺丝
What made you just replace it with an OEM radiator vs replacing it with an upgraded version such as a Mishimoto or CFS??
Will this man ever show his face. The world may never know.
