<x-charset iso-8859-1>Joe asks: discribe what to look for so I can see of that is part of my problem. Here goes... The bellows would be on the passenger side, situated underneath #1 & #2 cylinders. The bottom of it is attached to the lower cooling tin. The top of it is attached to a linking rod. You should be able to see it if you peer under the car on the passenger side and look at the pushrods. It'll be sitting right below. There are a two metal rods and a pivot on top of the head on the 1&2 side. One rod extends from the pivot downward through the head to the bellows. The second extends from the pivot rewards to the fan housing. The flaps are inside the fan housing. Pretty hard to see without removing the cooling tin. I suppose you could remove the hose to the heater box and peer inside the fan housing through this opening. I'm not sure you'd really be able to see them though. How it works... and I may be wrong about this. When cold, the bellows is compacted and effectively shorter, causing the link attached to move downward, and using the pivot causes the second link to move forward, which causes a rod in the fan housing to rotate swinging the flaps closed. As it heats, the air inside expands, causing the bellows to become larger (effectively taller) pushing the first link up, the second link rewards, rotating the flaps open and thus allowing the cooling air to flow over the cylinders. That somehow sounds wrong. I don't think I understand how the bellows functions and may have got the two actions reversed, but you get the point. The bellows is the force and all the links connect the force to the desired action: adjust the flaps.
