How to get to the thermostat??

[pattypape]

Hi Everyone,

Going to do some work on the cooling system to repair weeping hose
leaks.
When the outside temps get cold the silicone hoses want to drop.
(sounds like me)
There are no leaks when the engine is hot.

So, I thought I would also replace the thermostat.
Months ago there were postings about replacing the thermostat on the
3208.
It referred to the mouting studs and how to access the mounting bolts
and nuts.
Does anyone remember how many of the bolts had a nut attached in the
rear? And which were treaded into the block??
I think, there are three hex heads on the front casting.

I don't want to remove a bolt and not be able to tighten it back up.
