How I Flushed The Cooling System on My Mercedes Gl450 With CHEAP Harbor Freight TOOL 

Mercedes Workshop Service Repair Manual You can buy it from eBay

So Zerex G05 yellow is fo Mercedes-Benz 1997-2016 Zerex G48 Blue is for Mercedes-Benz all models and I believe this is the OEM coolant Zerex G40 pink is for Mercedes-Benz 2014- to present. So I went with yellow, because older models. Use this coolant up to 2016 models.Thank you my friend. Appreciate the feedback

@@Ivan_Neykov well I have 2015 GL550 It’s filled with pink coolant Turbo reservoir and main radiator. I was told pink coolant for 2015 is correct coolant 👍🏻

I’m guessing you’ve been told from the dealership? Mine is 2014 and originally came with a blue coolant, but in the same time, my coolant system was full with crystals. I know for sure Audi is using the pink coolant as well. honestly, I don’t know I’m thinking in my case I can go with either one of them and it will still work

@@Ivan_Neykov I called FCP Euro they told me pink G40. When I when to local Auto Zone they did have yellow jug like one you used with blue coolant than they had gray jug with pink coolant. Both of the jugs had Mercedes Benz Audi and Porsche I opted for pink 👍🏻

It’s a good thing that you went through FCP euro because FCP euro will give you that OEM spec fluid that comes from dealership but just a different brand. for me I just checked FCP euro and they’re recommending the blue one and like I said that’s how my car came in the beginning and maybe in the future I will change it because the yellow it’s very hard to see in the expansion tank.👍😊
