The cooling system of a BMW vehicle plays a vital role in optimizing its operation. The primary function of this system is maintaining proper engine temperature. A coolant cycled throughout the engine helps to achieve this objective, which it performs by drawing heat away from engine and passing it through radiator for aeration. Flow of coolant is regulated by a thermostat, with the engine being equipped with temperature sensor for regulating external air-cooling fans. Owners of vehicles can schedule for BWA BMW Service Sydney offers to achieve the best performance. Three essential elements comprise the cooling system of a BMW.
BMW Hoses, Control Valves, Heater Core, Radiator and Expansion Tank
All these components co-function to facilitate transit and regulation of coolant flowing all across the engine. These materials are affected by exposure time in greater manner than their usage-quantities, owing to the kinds of materials utilised along with their constant contact with coolant. Eventual deterioration results from prolonged exposure to the engine coolant. As such, it is highly commendable to replace the coolant regularly and examine all hoses and piping periodically. Ensure replacing any hoses with signs of deterioration when draining and replacing the engine coolant. As a preventative measure, all hoses require replacement every few years.
The radiator, control valves, heater core or expansion tank normally get replaced or repaired if evidence of blockage or leakage exists. Visiting a BWA BMW service Sydney offers will afford you a competent technician to check out these components and ascertain their optimum operational safety and performance.
BMW Fans, Thermostat and Expansion Tank/Radiator Cap
The temperature control function relating to the cooling system of a BMW comprises of the expansion tank cap, radiator cap, sensors and fans as well as fan clutch. These parts function independently of engine mainly, impacting engine control via communication with the computer system of your BMW.
The thermostat is in essence a spring-loaded valve, with the temperature of coolant flowing through it determining its opening or closing status. Thermostats consist of an electronic switch that can activate the check engine light function, which provides adequate warning before actual failure occurs. This switch monitors both the rate and position of the thermostat and feeds the engine computer with a report. It helps with emission warm-up time and gives the best possible fuel mileage too.
The radiator cap or expansion tank is a spring-loaded valve that resembles the thermostat and reacts to pressure-variations. The water pump pulley is usually fitted with belt-driven fan blade that pulls air through radiator and employs a fan clutch for its control. The fan clutch facilitates “free-wheel” turning at higher speeds and turning with belt at low-engine speed.
BMW Water Pump
The entire cooling system of a BMW engine is operated by a water pump, which keeps the coolant flowing. A belt or gear drives the primary water pump, but a secondary electric water pump is applied in certain cases for improving the flow. The drive belt runs the water pump, but certain older models feature an external pump and belt that run off the crankshaft pulley using a separate belt.
Having technician from BWA BMW Service Sydney has today to conduct maintenance of the cooling system of your BMW delivers multiple gains. These include cutting down operational costs and enhancing overall gas mileage and driving performance.
