When changing an expansion H- block is the probe fixed in to the block or can I purchase the probe separately? Does anyone have a good image of how this works. Is it like a txv system where the probe mounts to the evaporator? What does the diaphragm on the block actually do?

It's all part of the expansion block it self. No probe to attach when vehicle uses an expansion block.
