BMW 3 Series Overheating

BMW overheating problem. The bmw 3 series for sale in south africa E36 model is known for an occasional overheating problem. This indicates to influence the 316 4 cylinder designs across the years of 1996 to 1999. That three series type had issues 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 see that your BMW starts to overheat and the water pump starts to appear a little noisy then what might have happened is the plastic impeller that the original water pumps were made of may have snapped. Even though pump is spinning it may not actually be putting any water through the machine this means. If your pump appears loud and your temperature measure seems to be starting the red then understand this pump changed 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 precisely and the system is clear of any blockages.It has been recognized that the BMW 3 series system seems to need constant topping up of water with no obvious signs of the water leaking from everywhere. Some garages have pointed the finger directly at the head gasket or say the head perhaps broken and moving water through. It's been recognized that people have discovered that after likely to the expense of changing the head gasket or head they have still had the same problem. One treatment can be that the thermostat housing itself can be bad. These enclosures may somewhat heave possibly as a result of temperature, helping to make a minor spot for the air too be driven in to the motor. An airlock will be caused by this in turn to the program and the water doesn't flow round as easily. It also seems that even after stress testing and leak testing of the engine this problem isn't easily detectable.So my advice should be to check always this item as your next port of call as it's a less costly alternative than likely to change the head or gasket and then finding out that the thermostat housing was the cause all along. At the same time frame replace any rubber hoses that be seemingly perished or don't fit snugly to be sure these can be ruled out for any errors.
