Keeping the temperature within is essential not just to keep you cool, but even your engine since that determines the performance of luxury vehicles. Hence proper repair works must be done as and when needed.
While cooling systems turn out to be the best friends when operating in the best of their conditions, repairing them might be the worst enemy if one doesn’t understand how the BMW cooling system works. To put in simple words, the cooling system maintains the proper engine temperature by circulating the coolant through the engine to pick up heat and then pass it on through the radiator to cool it down with the air. The coolant then passes through the thermostat valve so that the flow can be controlled, and most probably over a particular temperature sensor which will, in turn, control the external air cooling fans.
Just like any other luxury brand, even BMW has got three separate parts in their cooling systems. In the case of BMW, the pumping section is handled by the water pump, which in due course of time keeps the mixture of the coolant moving. The main water pump of BMW is driven either by gear or by the belt, and in many cases, the secondary electric water pump is used to improve the flow, and hence cooling. One of the most critical point in the operation of the pump is the driver’s belt which turns it on. Some of the latest versions of luxury vehicles have it as the engine’s timing belt, but in their previous models, the pump and belt are external and they run on the main crankshaft pulley which has got a V or at times a flat belt.
As for the BMW repair in Greensboro NC is concerned, the timing belt driven pumps should be replaced at the same time as that of the timing belt and the tensioner. The cooling pipe consists of hoses, the heater core, the expansion tank, radiator and any number of control valves. Because of the material that is being used, and there’s the constant contact with the coolant, all these parts in the system deteriorate more due to this than the extent of use. The cooling system’s temperature controls include all the temperature sensors, the thermostat, cooling fans and even the fan clutch. The function of these specific parts is to work independent of the engine but control the engine either through the cooling or sending the signals to the BMW electronic systems.
The thermostat is a spring loaded valve which operates depending on the temperature of the coolant that is flowing through it. Whenever one tries to find out whether there’s a sticking thermostat or not, one needs to notice if there’s high-temperature reading followed by the drop in a normal temperature. There might be many other conditions which would give similar symptoms, and hence eliminating all such possibility is a quintessential part of BMW repair.
Temperature control is essential and critical both for the performance and controlling the emission. Unfortunately, this is the most complicated system to troubleshoot without the right equipment and trained technicians. Make sure you have your BMW repaired to keep it calm and soothing within.
