Cooling

Your BMW cooling system is critical to the performance and longevity of your BMW engine. A BMW's cooling system works as a whole by circulating fluid to transfer heat away from your engine's vital internal parts. A cooling failure can leave you stranded, or worse -- complete engine failure. Don't risk your engine! A BMW cooling overhaul is preventative maintenance and should be done every 60k miles or 5 years. Regular inspection of all hoses, radiators, thermostat, expansion tank, water pump, fans, fan clutch will help you avoid catastrophic engine overheating. Don't ignore leaks, bulging or cracking hoses or low coolant warnings. Preventative replacement of key BMW cooling components is a must to keep your BMW running strong. Use our SEARCH BY MODEL feature to filter these items for your BMW.
