Antifreeze questions
Hi Guys, I have owned my 2005 SL350 since 2006 and it has never had the coolant replaced. I know that in the owner manual it says every 15 years but why is this since usually you have to change the coolant every 4 years?
BTW, if I do decide to swop it is their anything special I need to know. I recently treated myself to a two post lift and so I have good access.
Thanks in advance,

They use very good coolant and that's why the long change cycle. Likely your best bet for coolant replacement is Xerex G-05. It's compatible with MBX coolant and is readily available at most retail auto parts stores, and not too expensive. There's no secrets to changing it. Open the reservoir cap as a vent, and you can squeeze on the hoses to burp out as much as possible. After refilling, check it after several starts to top it off - it's self bleeding.
