Coolant top off
 

Is Zerex G05 50/50 a good coolant to top off 05 X? No need to mix.

Thanks

Hey B-Man, the search button is your friend.

Bleeding procedure can also be found on e38.org BMW 7-series information and links or here. As to why you need to top off, that sounds like it could be a completely different issue.

with no prior knowledge to actual chemical difference, isnt ours the blue colored one? Zerex is the yellow one and is formulated for MB

See above, I've made posts about G05 countless times.
