<VV> Engine Cooling Air Flow

[HallGrenn at aol.com]

I agree with Marc, but if you are saying that the front ducts are open  
(where the heater ducting attaches) then the thermostats won't open because you 
 have continuous full air flow out the front ducts.  I would permanently  
close the front ducts with pieces of sheet metal so the thermostats can 
function  properly allowing the engine to warm up and run as designed (you say 
the engine  is not in a Corvair right)?

John,

I'll tell you what I think it is and if I'm wrong,  I'll quickly be shot 
down
:o).

Basically, there is no cooling air  until the thermostats open the doors. 
The
fan just spins without moving any  air until the doors open. Of course this
assumes that all shrouds are in  place and operating properly.
