What Causes BMW 5 Series Coolant Leak?

[JuniperLynn]

BMW 5 Series Coolant Leak Causes: Cooling system sealing issues: Loose connections between the coolant reservoir and radiator in the cooling system can lead to coolant leakage. Pipe problems: Aging or cracked pipes may cause coolant leaks. Radiator issues: Corrosion in the radiator can result in coolant leakage. Coolant is a special additive-containing liquid primarily used in liquid-cooled engine cooling systems. It provides excellent performance features including freeze protection in winter, boil-over prevention in summer, and year-round anti-scaling and anti-corrosion properties. Vehicle coolant typically requires replacement every 2 years or 40,000 kilometers. This is just a reference interval - for commercial vehicles with higher mileage, the replacement cycle should be shorter. Since driving conditions vary for each vehicle, replacement should be based on actual usage. Regularly check the coolant level and replenish promptly if low. If suspended particles, sediment, discoloration or deterioration are observed in the coolant, replace it immediately and flush the system.
