how to top up coolant mercedes

When topping up coolant in your Mercedes-Benz in Malaysia, first make sure the engine is completely cool—opening the cap on a hot engine can cause scalding or dangerous pressure release. Pop the hood and locate the coolant reservoir, which is usually a white, semi-transparent tank labeled "Coolant" or "Mercedes-Benz Approved." Check if the level sits between the MIN and MAX marks. If it's below MIN, add the manufacturer-recommended Mercedes-approved coolant, like specs MB 325.0 or MB 325.5. The mix is typically 50/50 with distilled water, but always double-check your owner’s manual. Never use tap water or different coolant types, as these can corrode aluminum parts or create sediment that clogs the system. After adding, start the engine, let it idle for a few minutes, and turn on the heater to bleed out any air bubbles. Finally, recheck the level. A quick heads-up: If you’re frequently refilling coolant, it might signal a leak—get the water pump, radiator, or hoses inspected ASAP. Malaysia’s hot climate puts extra strain on cooling systems, so replace the coolant every 2 years or 40,000 km to keep heat dissipation efficient. Also, regularly clean bugs and dust off the radiator fins. Using non-genuine coolant long-term could void your warranty, and if you’re unsure about the process, reach out to authorized dealers like Cycle & Carriage or Hap Seng Star for pro help.
