The first thing you should to is to inspect the thermostat bellows 
when the engine is cold, to make SURE that it has not already failed 
and expanded. There should be ~1 cm of space between the top of the 
bellows and the bracket above it. If it's already pressing against 
the top of the bracket when cold, it has failed and it has nowhere to 
go as the engine warms up.
