Its probally obvious but couldnt find it in the Haynes book



whatever it is has a cable on it attached to nothing, cable has rusted through

guessing its got something to do with the heat controls ???

cooling flaps return !

whats it connected to ?

effect performance ?

It should be connected to a capsule that closes the flaps via the wire when the engine is cold. The closed flaps means the engine warms up more quickly, reducing wear. If the capsule or wire is gone the spring holds the flaps open. Its not a problem if the flaps are still sprung open in the fail-safe position. The problem is if the flaps are closed when the engine warms up because the engine will overheat. If you try turning the bar you should feel the resistance of the spring.

yes there is resistance still it flicks back is that correct even though the wire isnt connected to anything

Yes, that means the flaps are being held open. If the capsule is still mounted on the side of the engine (page 42 of the Haynes shows it labeled as a thermostat) you could try fitting a new cable. Chances are it won't be fitted or it won't be sealed anymore. My van hasn't had one for the 3-4 years I've had it.

many thanks
