Yes.

But the rest of this thread is correct - BMW cooling systems are problematic. Water pumps and thermostats should be replaced every 60k, and radiators and expansion tanks every 100k (at which point you might as well replace the hoses).

The 4 cyl cars also have two plastic cooling connectors which will crack. See http://www.318ti.org/forum/showthread.php?t=18066 for a 4 cyl cooling system rebuild.

Unless you know when the cooling system was last rebuilt, you should do a complete cooling system rebuild.
