Temperature part numbers

Hi, have searched, but find most mails regarding temperature gauge not working, recommend replacing the lot with VDO components. Not quite ready to do this as getting these, and done here in Hong Kong is not that simple. So can anyone give me LRart numbers for the sensor, the gauge, ans for good measure the thermostat..btw. Does this exist in a variant for hot climates? So far I have found that my defender 50th is practically identical to the 97 NAS.
Cheers, Tim

There is a good reason people recommend replacing with a VDO ... Added to that even jimmy who is a master land rover mechanic can't get LR to supply a working part ...

What is the issue you are having that you want to replace those components? If you unplug the wire from the sensor and ground it to the block that should tell you if your wiring and gauge are working if the gauge pegs fully hot. In my case I had a bad sending unit and the ones I was getting through Land Rover were incorrect. I ended up getting an aftermarket sending unit from Atlantic British which is working properly.

If yours is the same as a '97 you need this sensor and this thermostat. I don't know where you would find a new gauge. but you could probably find a used one if you post a thread in the wanted section.

Hi, thanks.. When I start up the guage generally slowly rises up to just above the blue marking, however after five mins or so this starts to drop, untill eventually bottoming out where it tends to stay for the rest of the journey. If I stop the engine but leave the ignition on, then the needle begins to rise again to just above the blue stripe. Given that everything has to be ordered from the UK, I tend to cover my bets, but will try what you suggest to narrow this down. Cheers, tim

Ground for the gauge is wonky I would bet. At least worth checking. Does turning on the headlights change the behavior?

Related question:

94 3.9l NAS: temp guage now goes all the way to hot, pegged, even when not running and ignition engaged. Just started yesterday. Seems persistent.

Based on Jymm's response, sounds equivalent to disconnected sender with guage to ground only. Thoughts? Solution?

it is grounding somewhere - check your wire. and/or run a new wire from the sender tot he gauge...just do this outside of the truck to confirm it is wire - not sender
