Phillis Posted December 3, 2010 Share Posted December 3, 2010 I changed the sender to the one that came with the steve parker, water kit, and it still reads the same as what the disco sender the end of the white, the pipes are just nice and warm, the thread is fine so would this work ? cheers http://cgi.ebay.co.uk/Land-Rover-90-110-Temperature-Sender-Transmitter-/140475900874?pt=UK_CarsParts_Vehicles_CarParts_SM&hash=item20b50423ca Edit original engine was a 19j turbo diesel,, the disco engine has a fine thread Quote Link to comment Share on other sites More sharing options...
western Posted December 3, 2010 Share Posted December 3, 2010 use either temp sender PRC2505 or PRC6663, both were fitted to TD vehicles. have you tried the temp sender frpm your original engine? at least you know it works with the temp gauge.

western Posted December 3, 2010 Share Posted December 3, 2010 Me not thinking i scrapped the engine oh dear. should have held on to it until the tdi fit was all complete, now you'll have to by one or both of the senders I've posted the numbers for.

del Posted December 3, 2010 Share Posted December 3, 2010 ive tried a prc 8593 , and i dont know what the original sender fitted on my conversion 200 tdi into a td 90 but both have produced a just under the red reading i dont know if any one has any suggestions of what to try next?

PRC8593 is a 5/8UNF threaded temp sender for a Defender 200Tdi, not a Disco 200Tdi, the 2 I mentioned above will fit & can't see any reason why they won't work with the existing temp gauge.

del Posted December 4, 2010 Share Posted December 4, 2010 mine is a defender 200 tdi block with a disco head and its got a defender thermostat and housing so its a 5/8unf thread but still seems to send out a high reading - Quote Link to comment Share on other sites More sharing options...
western Posted December 4, 2010 Share Posted December 4, 2010 there are a few slightly different temp gauges too, so it could still be a gauge/sender mismatch Quote Link to comment Share on other sites More sharing options...
del Posted December 4, 2010 Share Posted December 4, 2010 do you recon if i look out foe a defender 200 tdi temp gauge at the autojumbles that would solve it ? , its sort of panic over with the tempreture reading as the engine is warm to the touch even with the high reading , changed the heater matrix and with the cooler 200 engine ive noticed the heater isnt so hot is that normal?

western Posted December 4, 2010 Share Posted December 4, 2010 it might, my 110 was a TD with temp gauge PRC7311 it worked with the Defender 200Tdi temp sender PRC8593, the other temp gauges are AMR2070 fitted to factory built 200TDi vehicles & AMR2631 fitted to 300Tdi vehicles until the Td5 engine took over.

Phillis Posted December 11, 2010 Author Share Posted December 11, 2010 Are all thermostats the same size as the 19j is 82, and the 200tdi is 88, so would the one from a 19j fit ? http://www.lrseries.com/shop/product/listing/1856/602687-THERMOSTAT-82-c.html?search=thermostat%2082&page=1 Quote Link to comment Share on other sites More sharing options...
western Posted December 11, 2010 Share Posted December 11, 2010 The 82 thermostat will fit, a 200tdi standard factory fit is a 88degree stat. Quote Link to comment Share on other sites More sharing options...
Phillis Posted December 11, 2010 Author Share Posted December 11, 2010 would it cause damage runnin a 82 ? Quote Link to comment Share on other sites More sharing options...
Retroanaconda Posted December 11, 2010 Share Posted December 11, 2010 Doubt it, but the proper 200Tdi thermostat (ERR2803) is only about a tenner Genuine (and yes you want a genuine one, the others are rubbish). Quote Link to comment Share on other sites More sharing options...
western Posted December 11, 2010 Share Posted December 11, 2010 (edited) would it cause damage runnin a 82 ? No, but the heater might not be a hot, I tried a 82 in my 200tdi but decided to revert back to the 88.

crclifford Posted December 11, 2010 Share Posted December 11, 2010 Ralph, What's this 299tdi thing???? hehe. I can't remember what sender i used, but since the cold weather, and a bit before, my temp gauge wouldn't read above about 1/4 in to the white area and regularly doesn't come much above the end of the blue section (running td5 gauges and sender) is there another sender that could be used?? Many thanks Chris Quote Link to comment Share on other sites More sharing options...
western Posted December 11, 2010 Share Posted December 11, 2010 299 was just finger on wrong key, should have been 200 I use the 300tdi green top sender with the a adaptor fitted to my stat housing, it's wired direct to gauge too. Quote Link to comment Share on other sites More sharing options...
Retroanaconda Posted December 11, 2010 Share Posted December 11, 2010 Yep, the 300Tdi AMR1425 sender is the one you want to use the Td5 gauge Chris. I can't recall, you've modified you loom haven't you? The green-top sender as above, wired with a modified loom (so that it is passed through the speedo head), provides a running temperature of just to the left of vertical.

crclifford Posted December 11, 2010 Share Posted December 11, 2010 Phillis..sorry for the thread hijack James, Yeah used the AMR1425 and modified the loom..but it hasn't, recently, moved over to that position...it hardly moves beyond the first white upright....but i do have my blower on full and the hot air on max...not that hot, hot air comes out!!..when i do turn the heat down, then it moves abit. But at motorway speeds, i assume that there is alot of cold air hitting the rad (esp now!!!) and this is cooling the engine down. I've left the engine running for 20mins at rest and it hardly moves at all! maybe a new sender required when i get a chance to order and fit.

Mo Murphy Posted December 11, 2010 Share Posted December 11, 2010 I'd be curious to know the resistance of the resister in the speedo head. When I was playing with resisters in the sender line before we knew about the one in the speedo head, I found that 55 ohms gave a central, vertical needle at normal operating temp in my 300 in summer.

crclifford Posted December 11, 2010 Share Posted December 11, 2010 Mo, That is definatly beyond my skills! Electrickery and all that (and i have no multimeter thingabobby) Chris Quote Link to comment Share on other sites More sharing options...
Retroanaconda Posted December 11, 2010 Share Posted December 11, 2010 All it would take would be a resistance reading between pins 5 and 9 on the lower plug aperture. Next time I'm down the workshop I'll try it with one of my spare Td5 heads. I have one here but the multimeter is typically down there! PS: Chris, what make was your 300Tdi sender. Didn't come in a blue box did it? Quote Link to comment Share on other sites More sharing options...
crclifford Posted December 11, 2010 Share Posted December 11, 2010 James, Just checked the email...it was defo a 'genuine' one, no blue box for me on this one!! This is what i got from Britcar...1 x AMR1425, AMR1425 TEMP SENDER 300TDI - V8 4.6L GREEN (G) Chris Quote Link to comment Share on other sites More sharing options...
Retroanaconda Posted December 11, 2010 Share Posted December 11, 2010 I can only assume there's a source of extra resistance then, that's causing the gauge to read low. Or it's reading correct and your engine just isn't warming up of course, leaky thermostat etc. Quote Link to comment Share on other sites More sharing options...
