Date: September 1st, 1997
Subject: Engine Cooling Fan
Vehicle: Range Rover 1987 - 1993 NAS (HA-PA)

WARNING: Engine Cooling Fan may Explode. 
DO NOT stand near engine bay when revving engine.

The above warning is just that, a warning that could possibly save you from serious bodily harm if/when the engine cooling fan breaks/explodes into pieces.

Recently it has been found that the engine cooling fan, which is made of plastic and shrunk/molded over a center metal disc, which attaches said fan to the fan clutch, can and has exploded on a number of vehicles as listed above. During this "explosion" fan blades and related pieces can/have gone through the fan shroud, radiator, and hood (also related cooling hoses). 

It has been determined that these fan failures are both age and heat related. As the fan ages and goes through heat cycle after heat cycle, the main body (which the fan blades protrude from) will begin to shrink, which will lead to cracking and failure.
When the fan clutch locks up and the fan is engaged under load, the weakened main body, if already cracked, will further weaken itself, resulting in the main body breaking in two or more pieces as it breaks free of the center metal disc. In addition, weak fan blades will further weaken, which will result in their failure as well. If cracks are found it is suggested that high rev's of a stationary engine be avoided, thus decreasing the possibility of explosion/damage/injury. 

It is highly recommended that all owners check their engine cooling fan very carefully for cracks. If cracks are found, replace the fan immediately. The price of a replacement fan is surely cheaper than the replacement of the above mentioned items, or the possibility of bodily injury.
