Temp sender

I know when I changed mine Stina I was told I had to make sure it was P6 specific and not SD1 for example as I would get false readings. To be on the safe side I would just get s P6 only one.
 
Just to tag cheekily on this thread...I now have a (high comp) defender engine with a defender sender presumably. The temp is showing very low on the gauge although the heater is very warm! Do I change the sender to suit the gauge or leave it to suit the engine and somehow recalibrate the gauge?

Hi Dan,

The temperature sender should be suited to the gauge.
 
O'k , so sender fitted , now getting readings in the top end of the green ( after being assured it was sender for the P6 .) I know it,s not that high as the originl sender sat between the 8 and the 5 on the gauge . the original sender failed suddenly due to being knocked during the top end build . Also the fan controller hasn't triggered the fan so i know it's not getting that hot ( as well as just knowing ) Asked wins also and they could not say that there sender was P6 specific , so can anyone point me in the right direction for the correct one please ? I can't stand these things not being right , it may as well read one hundred and eleventy twelve as what it is at the minute :? :D
 
What you could probably do with is the correct Lucas part number so you arent guessing. Guess that'd be in the parts manual?

ok the manual just gives part number 610388 which doesnt show up on the landrover spares sites (which is where those numbers seem to be useful!)
 
We could do with getting a known good resistance vs temp curve from an original sender. Then we have at least some data to go on in the hunt for a replacement.

So you'd measure resistance with it at a known stable cold temp (I.e freezer), again at a a higher temp, and so on until you have it dunked in a plan of boiling water on a rolling boil. The more data points the better, time consuming though...

Similar to what you used to have to do with megasquirt to work out resistance curves, although now most popular curves are known.
 
I don't ever remember not having to specify what the sender was for, so I'd say P6 & P6B were different. Same applies to P6B & SD1, they're different as well.
 
Right , as happens on here this thread has got wound up with another one , and i don't want to corrupt Mr quagmires thread , so I'll try to bring it back here . Anyone know the correct temp sender for the P6B v8 ?
Go on Rich , put the relevant posts here , O.k it's your birthday weekend so we'll give you a bit of time :shock: :LOL:
 
I had a look at the NOS item that I have amongst my bit and pieces Stina, the part number agrees with that shown in the P6B parts book. The part number is 568055. I also did a quick search and found them here...
http://www.lrdirect.com/568055-Water-Te ... -Rr-Black/

The part number is the same, therefore one would assume that they are indeed the same. To seek confirmation, Rimmer Bros list a range of temp senders for the RV8, none of which agree with this part number. So, based on that, you would have to assume that 568055 is indeed the real McCoy!

The NOS item that I have has 8-60 stamped into one of the spanner flats. The one within my engine manifold also has something stamped into it, but as you would expect it is almost on the underside, thus next to impossible to make out. :roll:

Lets know how you go!

Hi Rich,

The original sender wasn't made by Lucas, rather it was made by Smiths.

Incidentally, the part number that you quoted above is actually for the coolant outlet elbow that is located on the front of the inlet manifold.

Hi Ron . That part number is the same as the one i bought , I see the one you linked to is made by brit part , it looks identical to the one i have However that number isn't stamped on the sender any where so i'm guessing it's a copy of the original . I'm pretty sure it would read the same as the one i fitted :?
I haven't tried waddams , i'll have a chat to them Monday .

Edit .
These two are also on ebay
http://www.ebay.co.uk/itm/RANGE-ROVER-V ... 1c37dc8ffb

http://www.ebay.co.uk/itm/P67-TEMPERATU ... 5d4535128a
Again they are listed for P5 SD1 and range rover as well as the P6 , so not specific to the P6 :?

Edit 2
Just found this
http://www.lrseries.com/shop/product/li ... ENDER.html

This gives the option of original or copy , it also says of the copy the part numbers are for identification only .
I'm wondering if the original option would be the one i need as the part number of that would actually be a part number if you see what i mean :?
I'd rather have some of your thoughts , feed back before i commit , i seem to of spent rather allot on the old girl of late :shock:

Hi Stina,

You won't really know for sure until you buy the original Land Rover item so as to make a definitive comparison. Down a similar path, the original oil pressure transmitter and the BMI replacement both share the same part number, and yet as we both know, the latter are best kept well away from the engine.

You know, there is now no substitute for using an infrared thermometer (in the US they're $25 at Harbor Freight and others) to take the temp right before the thermo housing on yr intake manifold.

If you read the whole thread i don't have an overheating issue , i just want the correct sender unit . The motor runs in the correct region of 82/85 degrees , the new sender is giving incorrect readings .
