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

Product Information

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. Coolants/antifreezes are coloured so you can visually see them; colour intensity can be an indication of over dilution. The different colours are non specific to the different types of antifreeze. The manufacturer can dye the product any colour they want. The colour is no guide to the actual type of antifreeze type and the label should be read before use.

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. 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. 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. Sealing and Gasket Protection : Coolant keeps the gaskets and seals in good condition, preventing leaks and damage to other components.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? 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 Mercedes 325.0 specification coolant was the standard formula during the early ’00s. It was a Hybrid Organic Acid Technology (HOAT) formula that Mercedes used right up until the 2014 model year. Any engine built after that will use the coolant listed in the next section. You can convert the pre-2015 engines to the newer coolant style; however, that takes an entire system flush and refill, which can be expensive and time-consuming. Here, drivers may choose between several brands, most of which are available in several colors. If you buy coolant from a part store, ask the sales representative to look up the correct coolant for your Mercedes-Benz. Mercedes Benz owners should ensure they have a coolant that meets manufacturers’ specifications. In most cases, the Mercedes-Benz engine coolant must meet MB 625.5 specifications. See the owner’s manual. 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.

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 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 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. ConclusionPerforming 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. 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. 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. 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? Antifreeze is the hidden hero of our car’s engines. If you don’t know how antifreeze works, it’s pretty simple. Antifreeze is added to the water in your engine’s cooling system that lowers its freezing point (and raises its boiling point too). It’s why the liquid in your radiator doesn’t freeze when everything else seems to be! You can choose a concentrated coolant that needs to be mixed with water or a ready-mixed one that can be used immediately. About our Antifreeze and Engine Coolant
