BMW 3 Series Overheating

BMW overheating problem. The the new bmw E36 model is famous for an intermittent overheating problem. It appears to influence the 316 4 canister types across the years of 1996 to 1999. That three series type had difficulties with original water pumps and head gaskets that weren't made of the same material as some of the different gaskets made by BMW.If you find that your BMW starts to overheat and the water pump starts to appear a bit boisterous then what might have occurred could be the plastic impeller that the original water pumps were made of may have snapped. Even though the pump is spinning it may not really be moving any water through the system this means. If your pump sounds noisy and your heat measure is apparently going into the red then get this pump improved as your first provision. The revised pumps must have metal impellers to fix the problem. If the engine still seems to be overheating and the heater seems to be blowing cold air out check the thermostat is beginning properly and the system is clear of any blockages.It has been known that the BMW 3 series system seems to need constant topping up of water with no obvious signs of the water dripping from anywhere. Some garages have pointed the finger straight at the head gasket or say the head perhaps cracked and moving water through. It's been recognized that people have found that after going to the expense of changing the head gasket or head they have still had exactly the same issue. One cure can be that the thermostat housing itself can be bad. These enclosures may somewhat twist maybe as a result of temperature, making a slight area for the air too be drawn into the motor. An airlock will be caused by this in turn in to the system and the water doesn't move round as quickly. It also seems that even with pressure testing and leak testing of the motor this problem is not easily detectable.So my advice is always to examine this item as your following port of call as it's a less costly choice than planning to change the head or gasket and then learning that the thermostat housing was the cause all along. At the same time substitute any rubber hoses that look like perished or do not fit snugly to be sure these may be ruled out for any flaws.
