Hi all,
Today I've tried to replace a v-belt in my car.
I found that to do that, power steering pump needs to be released a little bit.

When I did so, I saw that pump is connected with some another device. What's that? There is a number of tubes going out of this device and going to bulkhead. Is it maybe interior heating pump?

How those devices are coupled? It seems that only using a spring partly visible on the picture.
There was also some small plastic component, but I don't think it could pass any torque.
I want to be sure that I didn't miss any element, which could unnoticeably fall down.

Regards
Greg
