Bill,
  I do not see any sign of ducting to force air through the = radiator=20 instead of around
it........Do you have ducting that is not in the photo ??

Ok, I = recently=20 upgraded my computer to Vista and = had to=20 download some software to get my camera to talk to it=85So here are = some=20 pictures of my cooling install

 

Notice = the bypass=20 hole that you guys are talking about needing to plug.  This = hole is in=20 the housing which has been removed, so it is not a=20 player.

The = little rag you=20 see on the oil line is a high tech way of checking for a leak. (I = have=20 one!)

 

The red = wire is the=20 air temp sensor for the air after the radiator.  It is on top = of the=20 fan.

Hoses are = 1=20 =BC=94  The temperature sensor was moved from the left side of = the inlet to=20 the top

But is = reading=20 temperature as it enters the engine after the radiator. (coolest=20 place)

 

My = overflow catch=20 can.  I will be replacing this with a pressurized on as per = Lynn=92s = suggestions in a=20 previous post in order to introduce

An air = cushion=20 above the liquid under pressure so it will not be=20 =93locked=94.
