Re: bmw-digest V5 #132

Anthony - No fan shroud, huh?  That is probably your problem.  The 
shroud's purpose is to direct the fan's airflow through the radiator.  
Without it, the fan just kind off paddles the air around with not much 
being drawn across the radiator.  My '88 M3 has a shroud.  It is a one 
piece affair the same size as the radiator core.  A screw on each side 
holds it to the radiator and two tabs locate the bottom.  I looked on 
mine for a P/N but couldn't find one.  Price can't be too much, cheaper 
than a warped cylinder head caused by overheating.  look for signs of it 
being there once upon a time...the metal clips on the radiator tabs, wear 
marks, etc.  If I were to but anything for this concern, the shroud would 
be it.

Good luck,
