Land Rover Repair: temp sensor gauge and o2 sensors, o2 sensors, oxygen sensors

Question
hey i was wondering if you have any diagrams and instructions on replacing the temp sensor gauge on the bottom of my radiator and also some diagrams and on replacing the o2 sensors.  if you know of any good websites on how to repair diagram and instructions on a 2001 disco i would be soo happy.  i'm an e-4 in the military and don't have all the cash to spend on repairs so i'm trying to teach myself with trial and error on repairs on ol bertha for me.  thanx!

Answer
The oxygen sensors simply unscrew from the catalyst and the connectors unplug from the wire harness.  There are no instructions other than to make sure the wires are secured away from the hot exhaust.

The temp sensor just comes out of the radiator, too.  When you refill the system bear in mind that it should be filled with Dex Cool, the red stuff.  

If you ever need instructions on something the factory website is www.landrovertechinfo.com  For an $18 access fee you can download ALL the info that is available to dealer service techs.  That's as good as it gets, in terms of information and training.

There are also a number of articles on my company website.
