Heat Exchanger Lever - What does it do / connect to?

[ggn06awu]

Hey Earlybayers,

Silly question (I'm a newbie!), but given the heater cable attaches to the right hand side lever of the heat exhanger in the image below, I'm trying to figure out what the hell the big lever components on the left are actually suppose to do, and would connect to?!

Help most appreciated

That's a universal heat exchanger, the other lever is for when fitted to a Beetle.
