BMW recommends coolant changes every 3 years. This video demonstrates how to change your own coolant, draining from both the radiator/expansion tank in addition to the engine block.

Parts Required:

~2 Gallons: Distilled water

You guys are truly a gem within the E39 community. Keep em coming! Personally I'd love some more vids of suspension component replacements.

You are very blessed to have so many iconic bm's in your arson. My dream beemers are the M5 and and 540I and the 850I. Best vehicles ever build

Ryan such a great teacher! Sure wish we had a shop like yours here in NC. Impressive how well you look after your customers cars.

Love watching you channel, although I have sold my m5 going on a year now, I have a 2003 540i msport 6 speed with 50k original miles. I have followed you since 2017 and have always enjoyed the content, lol the Ohio days were my favorite.

I have to completely flush my coolant on my 540i. The previous owner drained the blue and put in green. I have a list of parts I'll replace when I do this, so it'll be a pretty in depth job.

Right now it's in the air to add transmission fluid and I'm visually inspecting as much electrical connections, fuse boxes and relays in search of the elusive battery drain problem.

Another video demonstrating the proper way to get a job done on a BMW. Make sure you dispose of the old coolant properly. Our community has free drop off locations where I assume/hope they recycle it.

Hi Ryan! You are a wonderful resource to the E39 community. I have a qq… I’m planning on replacing my yellowing expansion tank. Do I still need to drain all the coolant? Reason I ask is that the car recently had a full flush done. Thanks!

See you Monday for my e60m5 thermostat!

Thanks for the excellent video. Clearly thisis the best way to do it. What is your opinion of the "vacuum cleaner" type machine that many dealers use? I've used those during DIY events on my car, how much coolant do they get out? TIA.

Thanks for your video. Can I please ask what stereo head unit is in that car? I noticed the Bluetooth and iPhone on the display and that’s exactly what I’m looking for to modernise my e39 m5. Thanks

Hi Sr.

How to bleed the coolant system? If you could explain it I would appreciate it.

Hello Ryan, could you provide the part number for 10 mm undertray screws which always go missing? Mine are missing too, but I can't find the part number anywhere, thank you.
