How to disconnect vac lines?
I would like to get at the attachment bolt for the thermostat housing on my 89 but these vac lines are in the way. How can I disconnect them without removing the plenum and fuel rail?

The rubber piece (red arrow) that the plastic vacuum lines go into unplugs from the EGR solenoid. It might be stuck on there after multiple years. Pull hard. Watch out for brittle vacuum lines. They get hard from the heat.

I recently installed a 160deg T-stat in my '88 and believe I used a 6-pt box-end on that bolt.
I also had the TB off to do the coolant bypass to two of those vac lines were easily movable enough.
As you raise that bolt the EGR Sol (fastened by that bolt) becomes a bit movable so it may not be necessary to disturb the vac lines to/from the Sol.
