I got the old "coolant level low" notice today. Went MB to buy my $30 bottle and the lady said "yeah, think its the red one". Can someone confirm this is the right product? Pic attached here.

Thanks! Should I be doing a fluid swap or is a top off okay? That is once I get the right product. How does the dealership sell me the wrong stuff?!

open the cap man.... obviously when its not hot. Thats bc people at the dealers arent into cars and havent got a clue.

Gotcha, wasnt sure when a full fluid swap was advised. Im at 35k miles. I've done brakes and oil changes so I should be able to add antifreeze :-D

Top off, posted sheet to show coolant specs.

Copy, thank you. Will also be swapping my aux battery this weekend as well. I see you have posted instructions for this process on various posts without the cheeky "search the forum first". Appreciate it.

This is what I've been using on all of my aluminum block engines for the last 100 years: (IIRC Porsche & MB both rebrand thiese products, add a dye and sells to the consumer for $$$. Be sure to mix with distlilled water (found at Walmart, etc., for cheap$) Note: Add frequency to the mix...change your antifreeze and brake fluid (flush) at the same time...(every two years).Your head gaskets, brake lines & components will love you 4-eva !
