Original Concentrated Antifreeze Mercedes-Benz MB325.0 1 liter, A0009890825 20

Product Information

Cars made before 1998 usually need antifreeze that isn't OAT-based and does contain silicate. Antifreeze at Halfords Sometimes, albeit unlikely, you'll be firm to smell an odd burning odor coming from under the hood. How naturally you need to flush and replenish your vehicle's coolant relies on the type of coolant. There are many types of coolants. Interestingly enough, up until the mid-1990s there was basically only a single type of coolant. It was a green formula coolant that contained corrosion inhibitors that only lasted between 24,000 - 36,000 miles or between two to three years. This type of coolant is not recommended for newer vehicles which come equipped with a longer-lasting coolant. 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.

Most commercial antifreeze formulations include a glycol (to suppress the freezing point and raise the boiling point), corrosion inhibiting compounds and a coloured dye (commonly orange, green, red, or blue fluorescent) to aid in identification. A 1:1 dilution with water is usually used, resulting in a freezing point in the range of minus 37 °C to minus 42 °C, depending on the formulation. 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. 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...

How often should you change coolant in a Mercedes-Benz?

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 Understanding the role of coolant in your Mercedes engine can help you appreciate the importance of keeping the system in optimal condition. 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. 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.

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? Lift the hood and locate the coolant bottle within the engine bay. This will be a plastic tank with a cap on top of it. 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.

The best mixture is 50/50 concentrated coolant with distilled water. A lot of people run 60/40 thinking that it gives them better boiling/freezing protection. In terms of heating that's absolutely false, ethylene glycol has a lower specific heat capacity than water (quite a lot lower actually). So water can absorb more heat for a given unit of mass than ethylene glycol. The boiling protection comes from the radiator cap, which raises the pressure inside the cooling system by about 5psi when things get hot to prevent the coolant from boiling. To have good boiling protection, you need to make sure your cooling system can maintain pressure. As for freezing, a 50/50 concentration protects down to -38c, which is more than adequate for all places where people drive Mercedes (unless there are some Mercedes dog sleds for those living in the arctic circles). If you live in an area of extreme heat, you should consider doing a 40/60 mixture. The extra water content will help keep temps low, and there is still adequate corrosion protection. 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.
