Lee:
The thermostat is on the side of the engine block, right next to the
turbo. You must remove the air pipe between turbo and filter, then
reach back and remove the two screws holding the thermostat cover on
more or less by feel. Don't remove the three bolts that hold the
housing to the block, it's likely to leak later if you do (I think mine
does).
Thermostat must be installed correctly (there is a notch in the body,
make sure it engages the housing or the cover won't seal...).
Other than bending over at the waist for a couple hours swearing, this
isn't bad.
