BMW 850CI Parts - EZ Returns & Flat-Rate Standard Shipping on Any Order

Here’s a fact from the American Automobile Association: 90% of all roadside breakdowns are caused by cooling system failures. The good news is that when it comes to your BMW 850CI, this is one of the most preventable situations. It is helpful to understand the BMW 850CI parts that make up the cooling system and how they work.

Without those BMW 850CI parts working together to circulate coolant (generally a 50/50 solution of dihydrogen oxide and ethylene glycol), that precision engineered motor would soon be reduced to a smoldering pile of fused scrap metal in short order. Among these BMW parts, the star (aside from the radiator) is the water pump. Like your heart, the water pump makes sure that the engine’s lifeblood (see above) circulates through the engine’s water jackets. The BMW 850CI not only has a belt-driven water pump, it has an auxiliary electrical water pump as well. It’s usually good for about 100,000 miles, and doesn’t require any special maintenance beyond that. BMW 850CI parts such as the coolant hoses should be checked periodically for cracks and abrasions, especially if they’ve been installed for 30,000 miles or more. Because they are made from rubber, these will become brittle and crack over time, so keep an eye on them. Less expensive discount BMW 850CI parts include the thermostat and the radiator cap. This device is basically a spring-loaded valve that maintains the coolant level at a specific pressure. This should never be replaced with anything other than a factory-authorized replacement unit.
