When there is not enough coolant inside the cooling system, the coolant (if any) will lose its ability to cool the engine. When an extensive amount of coolant is missing, the engine will overheat within a few minutes. Cars made before 1998 usually need antifreeze that isn't OAT-based and does contain silicate. Antifreeze at Halfords So, there we go. Hopefully this information has been useful, if you have any further questions not covered here please ask and I will try to get the answer. 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. Traditional or 'standard' coolants for systems with aluminium components use silicates for corrosion protection and these tend to 'drop out' over time hence 2 year service life. Some manufacturers switched to OAT as it lasts longer and some engines don't like the stuff- one/some of the corrosion inhibitors in certain types/brands can soften some plastics over time... dexcool is one of the usual suspects associated with this, specifically the inhibitor 2-EHA

Temperature Control : Coolant helps regulate the engine temperature, keeping it from getting too hot and causing damage.It is always best to use the engine manufacturer’s advice. If engine contains yellow metals [copper and brass as in older vehicles] then the long life products based on organic technology should not be used. As a general rule, most modern engines require the long life organic antifreezes. If the engine coolant level is low, add the recommended Mercedes-Benz engine coolant directly to this coolant tank. 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... 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.

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. In the case of a pre-mixed coolant, filling up comes down to pouring it into the coolant bottle. Concentrated coolant (antifreeze) must be mixed with distilled water before usage, usually in a 50/50 ratio. Why does my Mercedes-Benz lose engine coolant? 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. Maintaining your Mercedes coolant system will protect your engine from damage, avoid overheating, and ensure optimal performance. Trust our expert Mercedes specialists to keep your vehicle’s cooling system in top condition. There are different coolant options available for your Mercedes. The two most common types are Ethylene Glycol and Propylene Glycol.

What is the correct engine coolant for Mercedes-Benz

Coolant and antifreeze is a topic we are asked about on a regular basis, and often causes confusion; types, colours, service life etc. Performing a coolant flush on your Mercedes-Benz requires expertise and tools beyond regular vehicle maintenance tasks. Attempting such a task at home without professional experience can result in significant risks for yourself, your vehicle, and the environment. We strongly advise against this procedure at home to avoid such risks.

types of antifreeze offer better corrosion protection so that parts don't need to be changed as often.

Conclusion

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. So why is coolant important? Coolant is necessary for transferring the heat of the engine in a safe way. It prevents engine damage by limiting the range of temperatures an engine has to endure. If the engine is exposed to either freezing or boiling, then excessive damage might occur. A good coolant will include an antifreeze so that even in very cold temperatures, your engine is protected. Which cars does show Top Up Coolant See Owner's Manual warning message? 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 None other than the user may want to use the pre-mixed product due to ease of handling or cost and visa versa. So a warning message has popped up on your screen, that reads something like this: “Top-up coolant: see owner’s manual for warning message”. Don’t panic, it is as simple as it sounds. It is just time to top up your coolant. Here, we run through a few top tips for topping up your Mercedes with the specially formulated Mercedes-Benz C-Class coolant. How to top up your coolant
