Did you replace the radiator pressure cap? With a 14 psi (or higher) radiator cap you can raise the engine and radiator operating temperature up close to 250 degrees F. at sea level. If you are operating at higher elevations than 5000 ft. you will not be able to operate at such engine temperatures.
Did you absolutely get all the air pockets and bubbles out of the cooling system before having driven for periods longer than 5 min. You shuld have an air bleeder port in the top of your thermostat housing. This air bleeder needs to be vented each day for a week when the radiator has been opened or removed. If your reservoir tank appears to be losing fluid each day, that is a sign there is a coolant leak, or air in the system. You must fix all leaks and be able to operate your engine above atmospheric pressures before you can eliminate your overheating. You can relax after you cross a burning hot desert or race up a mountain at maximum allowed speed.

I've been a BMW technician for 20 years and I'm not sure what an "upper radiator engine spout" is, but have you checked your thermostat? How about the fan clutch? The radiator might be clogged. Does coolant flow through the overflow tube? Has the system been flushed and refilled with 50/50 mixture of anti-freeze to water? All of these things should be checked. Finally, did the engine overheat to the red? If so, you may have a cracked head or blown head gasket.
I think I asked more questions than you did ;-) Sorry I'm just trying to point you in the right direction.
Hope this helps, good luck!

It is most likely the case that you have a blown head gasket. Find a quality auto repair facility and have them use an exhaust gas analyzer to check for hydrocarbons in the coolant. This means that hot combustion chamber gases are leaking into the water jackets around the cylinder and when this happens, the gases evaporate some of the coolant and super heat the rest, which when it goes by the ECT sensor indicates that it is way too hot. A head gasket can be blown and not be severe enough to cause smoke out the tail pipe, and if the leak is only to a water jacket and not an oil passage, then oil and coolant will not mix.

If the cooling system is staring to fall apart on you then it is a good chance the radiator is blocked. take the car to a radiator specialist like red devil the can check and if nessesary replacs the radiator and power flush the cooling system for you.

my guess well its not really a guess but more of a promise. if you have more than about 150000 miles on it its going to be a blown head gasket get it fixed before your car stops working completely. go to a bmw specified shop.
