Replacing Thermostat & Housing - Is it Easy or Hard?

I have done it without removing anything else, but it is a bit of a fiddle! It should only take 5 minutes to remove the battery, battery box and ECU so long as the mounting bolts for the box are not seized solid. Then you will have plenty of room to access the housing.
In such case, do you remove the battery without having to provide an alternative power source? Do not you lose any computer data if you just remove the battery? I have similar problem with my MINI 2003 and just hesitate to remove the battery, being afraid of not being able to restart the car later.
