BMW (E24) M635 M535 M88/3 - Cooling System Flush

Get that green stuff out and replace it with the right blue stuff (G48), don't forget distilled water.

God bless this man

Thanks for this. Need to do this myself. Good looking car!!

[@slownrusty]

Thanks and you're welcome! Best of luck, its straightforward.

Another great video love the explanation and great tips make a daunting task so much more achievable. Beautiful car in a great iconic colour

[@1983dmd]

If I am not mistaken, you are now using the Zerex G48 now ...You are sooo right about owners neglecting the coolant change on these M88/3 engines. What are your thoughts regarding using a Fumoto F106N valve for easier coolant drain in the future ? Too risky?

[@slownrusty]

Yes that is correct, I wouldn’t bother adding that Fumoto drain valve

[@jamjestlx]

Beautiful car!

[@slownrusty]

Thank you kindly

[@Mikevicess]

Sources for water cooling parts would be big time

[@tajinderpanesar7721]

Do you need any special tools when working on a m series BMW ?

[@slownrusty]

No special tools needed.

[@davidaghajanyan967]

What did you paint the side window trims with and how did you refinish the front grilles? About to do the same to my E24 too!!

[@slownrusty]

I recommend satin black Krylon Fusion 3D

[@Akourmadas]

@@slownrusty interesting choice! I would’ve expected krylon to have a hard time sticking cleanly to that material. How did you prep the water gutters? I agree it looks fantastic

[@slownrusty]

@@Akourmadas - I used 350 grit and then lots of cleaning to remove contaminants, dust etc. the prep is the most important stage of the process
