DEX-COOL has had many complaints about clogging the system and is no longer used by GM. Anyone who is using it should drain it and flush well and use ZEREX G-05 (yellow) or the Mercedes recommended coolant (blue) instead which are the recommended coolant type for these cars. The formulation is made for the job and DEX-COOL is not as it is the wrong type. The coolant recommended is the HOAT type, Hybrid Organic Acid Technology, let’s face it anything with organic in its description costs more, from Apples to ZEREX. 🙄
Save money now on the wrong coolant and the cars cooling system will clog and corrode, your choice.
