Coolant also serves as a lubricant for components of the engine’s cooling system. It helps prevent corrosion and rust and provides protection for gaskets and seals. There are different coolant options available for your Mercedes. The two most common types are Ethylene Glycol and Propylene Glycol. Newer coolants use an Organic Acid Technology (OAT) and last up to twice as long as older coolant. In some cases these long-life coolants can last over 5 years or 100,000 miles. At South Coast Garage, we have a team of experienced professionals who can provide you with reliable and high-quality service to meet or exceed dealership standards. Our service employs only the best coolant, ensuring optimal results for your Mercedes-Benz while preserving your manufacturer’s warranty.

Mercedes recommends a coolant flush and refill every 30,000 miles or every two years, whichever happens first. Truthfully, you'll be fine to run the same coolant for a bit longer than that, but the antifreeze's cooling and protective properties won't be as strong as they were. That is especially the case with the older 325.0-spec Q1030002 and Q1030004 bottles of antifreeze. The newest 325.6 formula, part number Q1030005, has improved durability, so it should retain its properties for longer. Coolant, as it relates to vehicles, is constantly a liquid or gas substance used to regulate the temperature of your engine. Liquid coolants are usually half water and half ethylene glycol. Water is used to transfer heat while ethylene glycol is used to lower the chilly point of the liquid. In colder climates, this is highly difficult. Interestingly enough, this isn't the first time you've heard of ethylene glycol as it is the primary ingredient in the prominent term "antifreeze". Keep in mind, you never want to pour antifreeze or water by themselves into your engine system. They need to be combined to create the normal coolant.

The recommended interval for replacing Mercedes-Benz coolant can vary depending on the specific model and type of coolant used. As a general guideline, Mercedes-Benz suggests replacing the coolant every three to five years or approximately every 30,000 to 50,000 miles. However, these are general recommendations, and the actual replacement intervals may vary based on factors such as driving conditions, climate, and the coolant type used. The coolant MB supply is typically G48 or G05 both of which are HOAT. G48 can be green, blue or various bluey greens/greeny blues depending on brand. G05 is typically dyed yellow/amber.

I'll give my input here. The color of the coolant doesn't really matter, what matters is the specification. You're looking for a MB 325.0 approved coolant. The reason why color shouldn't matter is because once upon a time, coolants were colored because of the chemicals contain inside. But these once upon a time coolants are far too old to be used in a modern engine (and using them will likely lead to damage). Modern coolants have their colors chosen arbitrarily, because all the ingredients in extended life coolants (the modern breed) are colorless.During the coolant flush procedure, our expert technicians will inspect your radiator, water pump, belts, and hoses for any signs of leaks or potential issues. Our proactive approach to detecting problems allows us to fix them earlier on before an issue can get any worse, thereby saving you valuable time, stress, and money.

Antifreeze is going to go right into the heart of your car's engine, so choosing the right one is veryCars made after 1998 normally need antifreeze that uses silicate-free, organic acid technology (OAT). These Freeze and Boil Protection : Coolant’s additives will stop the fluid, and in turn the engine, from freezing in winter and boiling in summer, so your car runs safely in any weather. Also, be sure to properly flush all of the old coolant out if you're updating an older engine with the HOAT chemical formula to the newest Si-OAT chemical formula. Mixing the 325.5-spec with the 325.0-spec will cause accelerated wear of cooling system components. What Else Can I Do For My Cooling System? Choosing the right coolant is a minefield. If you use the wrong kind of coolant, with the wrong type of additives, then corrosion to engine components might be a problem. Unfortunately, it can take up to a year for this kind of corrosion to become obvious to the driver, and even then is generally misidentified by drivers as a radiator problem. The right coolant is therefore important for the health of your car. Start by identifying which coolant is designed for your make of car: Mercedes-Benz offers a range of coolants designed specifically to the specifications of their cars. These are ideal and offer great peace of mind for the careful driver. Make sure that the coolant also has either a type of silicate or a silicate-alternative present to prevent corrosion over the long-term. Choosing the correct fluids for your car is one of the most daunting tasks for a new DIYer. The local auto parts store will have walls lined with oils, solvents, and fluids as far as the eye can see without the definitive information you need. Choosing the right engine coolant is no different. Is it the green kind or the pink kind? Maybe the blue one? In Mercedes’ case, it could be any of the three depending on which engine you have. Coolant composition has changed over the years as engine system materials have evolved for better efficiency, so you’ll need to know which one is for your Mercedes before topping up your cooling system.
