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.

Latest Q&A

Q
When should you not wash your car?
It is not advisable to wash the car immediately during hot noon or after heavy rain. Under high temperatures, rapid water evaporation tends to leave water stains on the paint surface, and temperature differences may cause the car paint to crack. After rain, acidic rainwater and sediment adhere to the vehicle's surface, and direct rinsing will exacerbate paint wear. Additionally, if the vehicle has just been driven through a construction site or dusty area, wait for the engine to cool before cleaning to prevent sediment from scratching the paint. When parked under trees for extended periods, remove corrosive substances such as bird droppings or tree resin first, as high-pressure washing may force them into the paint. It's recommended to wash during shaded hours or on cloudy days using a neutral car shampoo and following a top-down approach. Black vehicles require more frequent cleaning to prevent visible water stains. Regular waxing or sealant application enhances the paint's stain resistance. During the rainy season, a brief rinse can be done weekly, but ensure thorough drying to avoid water spots.

Q
What do car detailers do when it rains?
During rainy days, car detailers take targeted measures to protect vehicles. First, they avoid outdoor car washing or painting during rainfall, as the acidic components in rainwater may corrode the paint and affect work quality; professional facilities prioritize indoor operations. For waxed vehicles, light rain requires gently wiping the car body with a soft towel after the rain stops, while heavy rain necessitates sending the vehicle to a detailing shop to inspect the wax layer condition and perform re-polishing. Film installation actually benefits from rainy conditions, as humidity reduces electrostatic interference, but strict glass cleaning and post-installation care—including avoiding window operation for 72 hours—are essential. For routine protection, owners should regularly apply wax or ceramic coating to enhance paint corrosion resistance, promptly remove standing water after rain to prevent stains, and check wiper functionality and sunroof drainage. For extended parking, using a garage or car cover minimizes potential rainwater damage to the paint, chassis, and electronic components.

Q
Can you use toothpaste to remove car scratches?
For minor car paint scratches, toothpaste can provide a certain repair effect. This method is primarily applicable to fine scratches that only affect the clear coat. The abrasive particles in toothpaste can help fill in scratches through polishing, while its humectants blend the scratches with the car paint color. When applying, use a soft cloth to gently rub a small amount of toothpaste in circular motions, then rinse with clean water. However, note that this method has limited effectiveness on deep scratches where the primer is exposed. Post-treatment issues may include reduced gloss or temporary disappearance of scratches, particularly after rain or car washing. Moreover, frequent use of toothpaste may cause paint wear due to its abrasive nature, so it should only be used as a temporary solution. For severe scratches, professional touch-up paint or polishing is still required. For routine maintenance, specialized car wax or scratch repair products are recommended to ensure more durable and stable paint protection.

Q
What should you never clean with a magic eraser?
Magic erasers are suitable for various scenarios due to their strong cleaning ability, but they should be avoided on high-gloss surfaces, electronic devices, and delicate materials. Their abrasive properties may scratch high-gloss furniture, countertops, or the anti-glare coatings on electronic device screens; it is recommended to use microfiber cloths or specialized cleaners instead. They are also not suitable for car paint surfaces, non-stick cookware, and stainless steel surfaces, as they may damage the coatings or cause irreversible harm. Be sure to test in an inconspicuous area before use and wear gloves to prevent skin irritation. Although they do not contain chemical toxins, their physical abrasiveness means that cleaning objects must be chosen carefully, and mild alternatives should be prioritized to ensure the safety of items.

Q
Can Mr. Clean be used on cars?
Mr. Clean Glass Cleaner can be used for cleaning car windows, but caution is required. This product effectively removes grease and water spots without streaking. Its mild formula is non-corrosive to glass, but avoid direct spraying on automotive paint or plastic components, as non-automotive cleaners may contain surfactants that could compromise protective coatings with prolonged use. Professional automotive glass cleaners like Turtle Wax are recommended, as their formulations are specifically designed for road film and insect residue removal while being paint-safe. For temporary use of Mr. Clean, spray at least 15 cm away from wiper rubber blades, allow 30 seconds dwell time before unidirectional wiping, and promptly rinse residual cleaner from window edges. For vehicle exterior cleaning, use pH-balanced automotive shampoos like Cherry Foam Car Wash, whose lubricating foam encapsulates abrasive particles to minimize scratching while containing paint-protective additives. Notably, windshield degreasing requires automotive-grade products like Depu Tar Remover, as household cleaners cannot effectively dissolve bonded road film deposits.
