Brown Coolant

[Thraxbert]

is this a drain/flush from radiator lower hose and fill at cap? My coolant is brownish too and was looking to just a full cleanout and refill to try and see if it is still getting contaminated or if they mixed coolants at some point.

Yes. This is what I would do.

My local indy is asking for $200 and won’t use anything other than the blue BMW coolant. Would rather stay green so I’ll be looking around. Thanks for the info!

It has to be ht12 green. Nothing else! Get premixed from FCP Euro. I would flush the system first with distilled water

It does not need to be HT12. That is one of several compatible options, and is only the recommended one.

I would stick to the shop and owners manual
