Default Coolant Change Problem

I recently went through the process of draining and refilling with distilled water until it ran clear- now the thermostat appears not to be opening even when the temp rises to 220 and the electric fans kick in- The coolant tank is full with new dexcool I'm thinking that the thermostat must be sticking shut or is it something else? airlock? Anything short of replacing the thermostat that I might try?

did you burp the system?
modern thermostats are built to fail open.

My theromostat came with specific instructions ... running with the coolant system open is the key
here is a generic set
