Coolant (325.0 replaced by 325.5)




This car sees 4-5 track days a year. Not all that concerned with plastic fittings cracking any time soon.

326.x coolants are already premixed (diluted) 50/50 and ready for use.
325.0 (concentrated) & 326.0 (premixed) are blue G48 coolant.
325.6 (concentrated) & 326.6 (premixed) are pink G40 coolant.











I even linked the answer in the first post for lazy people.

All of the answers to your questions have been asked and answered in this very thread so I'm honestly not entirely sure what you're asking.
I will sum it up quickly anyway. MB says you can mix 325.0 (BLUE) with 325.5 (PINK) in an official document posted here --> https://mbworld.org/forums/c63-amg-w...ml#post8862946.
That however doesn't mean you should. If you are going to switch, I would recommend flushing your cooling system first.
Done, no more repeat questions.

Looks like you're starting to frustrate others about this as well.
