Overheating BMW

<br />You may discover you own one of the BMWs that suffer from an overheating trouble. This known overheating fault tends to materialize more on the E36 BMW models. The most affected model seems to be the 4 cylinder models of the 316 BMW 1996-1999. Head gaskets and water pumps on 3 series BMW cars For Sale of this time period were of suspect quality when they left the factory, meaning that this trouble could then arise.<br /><br />If you detect that your BMW starts to overheat and the water pump starts to sound a bit noisy then what might have happened is the plastic impeller that the former water pumps were made of may have snapped. This meant that whilst the pump was turning, the water was not going around. If your pump sounds noisy and your temperature gauge seems to be going into the red then get this pump changed as your first precaution Launch CReader 8011. The modified water pumps are made of metal instead of plastic.<br /><br />If once the water pump is checked, you find the car is still overheating, the second step is to check the thermostat, particularly if the heater seems cold. Some BMW 3 series tend to need constantly topping up with water without any signs of how it is disappearing to.<br /><br />Some garages have pointed their digit straight at the head gasket or the head maybe cracked and passing water by Autel Maxidas DS808. It has been known that people have found that after going to the expense of changing the head gasket they have still had the same problem. It has been realized that the thermostat housing could also be at fault. These thermostat houses can warp somewhat to let air seep into the cooling system. This will in turn cause an airlock into the system and the water does not flow around as easily. It has been established that this fault is not easily established even when the engine is pressure tested for leaks.<br /><br />So my advice would be to check this item as your next port of call as it is a less costly option than going to change the head or gasket and then finding out that this was the cause all along. Any hoses that look like they might need changing, should be done at the same time, to make sure there are definitely no other leaks in the system. The newer versions of the BMW 3 series and BMW 5 Series normally didn't seem to suffer from these type of overheating trouble.<br /><p><p>
