why is my temperture guage still reading high ?

hi, ive had a 200tdi disco engine fitted into my defender, and the temperature was reading high (almost in the red) so I bought the correct sensor from Steve parker and its still reading high, what do I need to do next please ?
regards

Have you checked it isn't actually running hot?

its had a good run today, all pipes and radiator seem the same temp but hot, its just the flipping gauge

Are all the wires correctly fitted I've just solved this problem on mine and had a bad earth fookin nightmare. When the engine is cold does it jump into the centre of the gauge on start up??

I'm not to sure about this but I'm sure I've read that the sender unit is different for a defender and a discovery. Did you buy a defender one. i dont think you can just fit one from a 200tdi discovery

The sender is the correct one I bought it from Steve Parker, and asked his advise, the temp gauge goes up gradually, it's not in the red but very close to it
Cheers

I have the same issue...

Checked the earth and thats fine.
Checked the actual temperture and that is normal (not over heating)

It heats up gradually as normal but just sits on the edge of the red, even when the fan is running.

...!

Yep mine is egzackly the same but my new sender is a britpart one and I have been told to buy a bearmac one and that should sort it

I know yours is a 200, but on my 86 defender temp gauge it reads just on the red when the 300tdi is warmed up. This is using a defender (black iirc) sender.

i checked with a temp gun and it's not overheating.

I think the 200/300 both run at 88 degrees. Anyway, the 300tdi temp gauge is different to the 86 one.

you can probably use some different sender combos, but if you add a variable resister inline with the temp sender, then you could dial the temp in to N on the gauge.
