You got a sender unit for a GT dash and not a standard one didn't you Phill? I used one out of a ZH in my GT dash, reads fine.

what part numbers etc have you tried? iv used a tirdon brand before and found it too read too cold

i normally use a VDO catalogue which lists a 320.003 which i sell here at rares as a XA10884A if that helps at all

And Merry Christmas guys. Phill, I'll try and pull the old girl out of the shed and get a photo of the sender unit in the next day or so. The reason I used one out of a ZH is because we were using a ZH as a donor car when we did the V8 swap into the XB. I knew a standard XB sender wouldn't work with the GT dash but if you ever look at a ZH temeperature gauge it's about the same size as a XA XB GT gauge so I took a punt and the thing read close enough to right for me. With anything electrical on the Goss always ask for GT stuff. Seems to clear the waters a bit.

I am not much on auto electrics and you guys might already have this sorted out with your part numbers.

I had the same issue with my temp gauge for my HQ Holden.

All fixed now. Basically I fitted a GTS dash and it had a temp gauge.

When I connected the sender unit, it was giving me a reading without the engine turned on. Ended up been the wrong omes. Did a bit of googling and all fixed. Mine is a VDO but no point telling you the part number as it is a whole different car.

Maybe google 302 cleveland temparature and hopefully you find something there.

Sorry if it is not much help.

This is a really good read for me. Must agree that you are one of the coolest bloggers I ever saw. Thanks for posting this informative article.

just another spammer from india, he is banned now anyway

hahaha, theres goes the self esteem HQ sandman lol.

Happy New Year to all, We are all back from our big trip safe and well, I'm real happy to say the Goss did well for our biggest family outing, we have travelled approx 1800kms and had a fantastic time in the south coast of NSW, then to the Northern Beachers and then back inland to the Southern highlands, and I must say I was very parranoid at first, but I got over that in the first tank, and I met many nice people who approched me who gave me nice comments on my car,one part I did enjoy was when I took a Aussie battler (a nice real guy)and his two boys for a drive along the beach, around the block and back to his wife,he told me "I would never afford a car like this" as he spent a while to save for his holiday,(I'm just lucky that a Welding TAFE Teacher gets paid more to afford a car like mine,after years of savings).
I did have a problem when it got hot and only when I went to excellerate it poped and backfired and seemed it was down at the rhs extractor so I took it real slow and tried to keep it cool, I think it could be a timing thing, but that's for later.
So just getting back to our conversation Big Cav, yes i did use the VDO 320.003 and used that on my trip and that was still reading hot and when I put the lights on it went hotter, therfore another trip to the Auto sparky to find the reasn for that, and thanks for getting rid of that idiot!
Paul, thanks for trying for the pics, but save your time mate, come to think of it a picture will not do much justice, I think they are all are just about the same.
HQ Sandman, the sender unit should be 75-10 ohms, the same as the guages (I think he said) and the wire that goes onto it is 5 volts and is correct, but, yeh your right,the sender has to be correct, also I did google the motor and it leads us back to this forum, I just had to laugh at that!(unless I screwed it up)but I have not tried the TTS010 and I may have tried the VDO 320.11 I would like to know where you got your information from, I also googled tridon and they say to use TTS024 and as big Cav says "It ran cold" therefore I'm not too sure what to do from here, but like I said as the temp gets hotter whilst the lights are on,so I will make a booking for the sparky and see if he has any answers on this problem, I will keep you all informed some time next week after we can sort this one out! Cheers guys all your help and information is always greatly appreciated, Thanking you, Phill.

Hi Phil,

Believe it or not, I googled Cleveland 302 Temp unit. Led me to some other forum.

I live on the south coast. A shame that I didn't know, I would of got you in contact with my mate who is an auto elec who would of found the problem for you. Even travels out to jobs. The TTS010 is worth a try then if you tried everything else.

Hey fellas, just some old news being brought back up again to conclude this topic,
After trying so many different types of sender units and all seam to have different but unusual readings, we have found that there was a bad earth behind the dash, the dash is a XB GS dash, as Paul mentioned earlier the guages can be different to a falcon 500, LTD, ETC,many of these sender units may have been correct but they can vary too!
Now I have the temperature sitting just below half and the outside temp was about 25degrees with the air con off and it ran pretty well, so I'm happy with that,so therefore I will leave it as it is for now,
at this moment I have a VDO sender installed in the car, part # 320.003
This did my head in, but I must thank you all for your input, so my problem to this nightmare was the bad earth in the dash, now I will know for next time,
Cheers,
Phill.
