Antifreeze not only suppresses the freezing point of your engine coolant, but provides good corrosion protection and increases the boiling point during use. 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. With that being said, the popular choices for MB 325.0 coolants are: Zerex G05 (slight yellow-ish tint), Genuine MB coolant (It use to be blue-colored Zerex G05), Zerex G48 (which is also blue, and the same thing as current Genuine MB coolant, and probably the same thing as Genuine BMW coolant). If those are not available, you also have Castrol Radicool which is 325.0.

Cooling systems’ harsh environment may damage sensitive electronic circuitry inside this sensor, making its readings incorrect. The easiest way of solving the issue is by replacing the sensor, which is easy to replace and inexpensive. In addition, damaged wiring and loose or broken connectors are something owners should not rule out. Conclusion Perhaps the most frequent cause of confusion is what the difference between anti-freeze or coolant is. Basically, they’re the same product (although the term “coolant” could just be applied to plain water; see below!) Halfords Motoring Club. Join today to access a range of amazing benefits and discounts that are designed to The older Q1030004, G48-spec stuff can be used in a newer engine like these, but only if the cooling system is completely drained and refilled. We strongly advise against mixing the two, which can lead to damaged cooling system components. 325.6/326.6-Compatible Engines (2014-Present): Coolant, also known as antifreeze, is a liquid that helps regulate the engine’s temperature and prevents it from overheating. It circulates throughout the engine, absorbs the heat generated by the combustion process, and transfers it to the radiator, where it is cooled before returning to the engine.Car maintenance is really important to avoid repairs and save you money, so don't forget that if you're pricing on all motoring products and services online and across our stores, garages and Halfords Mobile also use our handy online look up tool to find the right one for your car. A general guide to antifreeze 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. The error message does apply to every single Mercedes-Benz vehicle with diesel or petrol engine (except Electric Vehicles in short EV), so if you have mercedes benz in your garage sooner or later, this message will pop out on the car's dashboard.

You may be able to drive as long as the engine doesn’t overheat. Monitor the temperature gauge carefully. Where did the missing coolant go? Propylene Glycol, on the other hand, is a less toxic and safer alternative. It also has good heat transfer properties, but it has a lower boiling point than Ethylene Glycol. Coolant can be plain water; water is a very effective coolant but would not protect against sub freezing temperatures or protect against corrosion inside the engine. The use of antifreeze protects against both problems. Cars made after 1998 normally need antifreeze that uses silicate-free, organic acid technology (OAT). These As we know, not all engine coolant is identical. Different cars require different formulas with different colors to meet the manufacturer’s specifications. However, once you determine which formula you need, you can choose whichever brand you’d like. Genuine Mercedes coolant is one of the best ways to go as it is the exact stuff dealerships and the factory uses in brand new examples. We offer the latest specification stuff in its concentrated form in a gallon jug. Rowe provides a concentrated gallon of the older 325.0-spec coolant for use in the older engines if you’re looking for a non-Mercedes brand. Otherwise, you can use the official stuff found here.Ethylene Glycol has exceptional heat transfer properties. It efficiently absorbs the heat generated by the engine and effectively moves it away to maintain the correct operating temperature. However, Ethylene Glycol is toxic and must be handled and disposed of carefully to prevent harm to humans, animals, and the environment. You can ensure the longevity and efficiency of your vehicle’s cooling system by regularly replacing your Mercedes-Benz coolant. When you visit us at South Coast Garage, our specialised technicians will expertly flush, drain, and refill your coolant system with the correct coolant. You can trust us to keep your Mercedes-Benz running like new. Top Tips for Maintaining Your Mercedes-Benz Cooling System Every car manufacturer, including Mercedes-Benz has developed its own coolant or requires a discernible coolant that is unique to explicit years and models. There are many colors of coolants to aid distinguish each including yellow, red, purple blue, green, and orange. It is hard to do your research if you plan to pay cash for, flush, or replace the coolant in your vehicle. Several models will not be compatible even with "universal" coolants or antifreeze. is the usual spec for passenger cars and the approved coolants are typically the aforementioned G48 and G05. A w203 would've been filled with one of these when new i believe, exact flavour and colour would depend on who MB were buying coolant from at the time... To ensure your cooling system continues to work properly, it is crucial to use the recommended Mercedes coolant. Consult your owner’s manual or seek advice from a specialist Mercedes garage, like us at South Coast Garage, to ensure the correct coolant is used.

Sometimes, albeit unlikely, you'll be firm to smell an odd burning odor coming from under the hood. For the most accurate information regarding your particular Mercedes-Benz vehicle, it is always best to refer to the owner’s manual or speak with one of our Mercedes experts here at South Coast Garage. Our well-informed team can provide you with the manufacturer’s recommended coolant replacement interval, as well as any specific guidelines or requirements for your vehicle. Just about every Mercedes engine in the last 25 years is going to take one of two possible specifications of coolant, according to Mercedes. The difference between them resides in a couple of chemicals that have been removed from the newer coolant specification, Borate and 2- ethyl hexanoic acid to be specific. As such, the new coolant is compatible with older engines, but the old formulation shouldn’t be used in a newer application. Every diesel and gasoline-powered engine contains a constant series of small explosions while running. The fuel igniting in the cylinders creates the power that drives the car and sends us on our way, but as you might imagine, those explosions make things hot. Those explosions can weaken and warp the metal around it if left long enough, effectively destroying the engine components. Coolant and cooling systems prevent that, so your engine can last as long as it’s taken care of. Cars made before 1998 usually need antifreeze that isn't OAT-based and does contain silicate.

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.
