temperature problem ??????

I've got a 1986 90 ,that i have fitted a 200 tdi into , when travelling at speed the temp gauge goes to red but if you stop (even leaving the engine running ) the temp gauge comes down to normal fairley quickley .
lifting the bonnet the engine doesent seem over heated
THE n/a diesel fitted befoe the swop had a simular problem but not as bad
Can anyone help
thanksSteve

use the sender unit from the n/a engine

just had exactly the same problem , just put the na temp sender in it's something to do with ohms . how did you find the conversion , not to bad ehh.

i seem to remember it was me that told you to try that ricky boy

was that you , your my champion then ..

Same here......when going at about 60/75 the gauge is half way.but when around town..it drops to just above the first block.......then it went up to below the red then back to midway......could be worse i suppose, i used to have a P38 4.6 HSE......that would be another story

i never knew those temp senders were so technical , i wonder how many people have done this conversion and then filled there undies when they saw the temp . i even resorted to try dipping my elbow in the header tank but could'nt reach , (it's a big one ) , thats my landrover not my elbow.

From what you are saying.....my motor used to run the old V8, it now as a 300tdi.so should i / what should i change...??????????/

you could try the v8 sender if they fit , ( i'm no expert on sender's ) also you could think about a electric fan , you can set them to come on when you think it's needed , your's sound's ok on the motorway where there is a lot of air flow , but you still need a correct reading on your gauge . i can give you details if you want them .

thanks ill buy a sender tomorrow & try that
let you know howit goes.
the conversion went well "what a difference

ahem
