My guess, since the engine lid hasn't been opened in about a year, if that's
what I read, is that perhaps it's been running too cool all this time - this
is quite common in 2.1 waterboxer vanagons. And yes, you sure do have to be
careful with the 4 screws that hold the t-stat cover on the plastic
thermostat housing.
Just turning them with a socket can cause the metal nut in the plastic
housing to just spin, or the nut head to break off. Sharply rapping them
with a hammer and punch, as well as using penetrating oil well in advance
sure helps.
It's like if you do the right thing in the beginning, you can get the
t-stat cover off ok. If you hurt the plastic t-stat housing, then it turns
into a much bigger job.

And may I add that IF thermostat needs to be changed, be careful. I
recently read some thread in the archives that one part of the
thermostat housing is easily damaged. Not clear on the details, but
you might want to search the archives on that one.
Cheers,
Neil.
