<VV> Engine Cooling Air Flow

[J R Read_HML]

If the heater is not attached, you should block off the heater outlet on the 
shroud.  Leaving that open will make for poor or little air flow over the 
engine cooling fins.  It will exit out the top without passing over the 
engine.

The design is that the cooling air exits out the back once the doors open. 
There is very little (if any) cooling before that.  This assumes that lower 
shrouds are in place.

Later, JR
