Check this link out it explains how the cooling system work, its worth troubleshooting before buying parts

This really should have been posted in 'Tech Help',I guess that a friendly,or perhaps even an unfriendly one 
will move it!
Your cooling problem is most likely to be caused by a failed viscous fan coupling.

NOTHING needs 'upgrading' on an E30 (with the possible exception of the steering rack ratio). These were cars built with engineering as the first priority, very few corners were cut, and they sold for the price of a small house, especially if a few option boxes had been ticked.
Some things do deteriorate or fail in time however, and one of these is the radiator itself, which gets coated with scale internally and suffers from damage to the fins externally. This will show itself up as overheating in hot weather when the engine is being worked hard.
You say your overheating takes place when the car isn't moving, so that, as Daimlerman says, is likely to be a failed viscous fan coupling, between the fan and the water pump pulley.
