Hi guys,

this august i bough a 2007 CL63 AMG (M156). I remember there was a blue coolant. Last month my radiator broke and all the coolant leaked out. Now the shop put a new radiator but they put a pink coolant and said, the car should have this one. Searching the internet, all photos seem to have the blue one. Should I keep the pink one or change it? Which one do you use?

Thanks

In 2007 factory fill was Specification MB 325.0/326.0 (Blue HOAT Coolant).
Approx 2014 MB325.5/326.5 became standard (Pink Si-OAT Coolant).
Pre-2014 engines in the table below can run the newer Pink Coolant but it takes FULL system flush and refill (don't mix Blue and Pink)

Thanks for the info! I installed a new radiator. Do you know if there are any benefits to the pink one instead of the blue one? Any recommendation - stick to the blue one or use the pink one because it offers better results?
