Well with the help of the how to guide...I successfully changed my thermostat (CF2)
Few pointers that I'd add; don't use a socket set, its too tight on the bottom bolt even with an extension...I'd suggest a spanner (or the circular grip at the opposite end of the spanner don't know what its called!)
The odd clips that aren't jubilee clips don't need a special tool, a hammer and a flat-head screwdriver will prise them off and if you want to reconnect a standard set of pliers will pull them back together.
The hoses will need a lot of effort to get them off; again a flat-head screwdriver between the hose and the housing will help loosen them (be gentle and don't split the pipe).
Make sure you re-connect the bottom hose that you disconnected after doing everything - I got carried away after reconnecting all the hoses to thermostat only to then realise I hadn't re-done the bottom one when filling back up!
When tightening the new thermostat to the engine do each bolt one turn at a time or you wont get an even seal.
Apart from that, all is good - a steady 88 degrees!
