General TechHave a question that is not covered by one of the other categories? This is the forum for all other items not specifically covered in other categories.
My temp gauge in my ute is not working and never has. I dont think the gauge is faulty and I have a few spare ones to check if needed.
Im running an EB 6cyl in an XB ute. I think my problem is the temp sender unit.
Where is the temp sender located on an the 4ltr OHC block?
There is a wire hanging down from the loom (XB loom)in the engine bay located (looking at front of car) up near the firewall to the right hand side. Could this be the wire for the temp sender on the old non-cross flow 6cyl?
If it is, could I just plug this up to the EB temp sender unit and get an accurate reading? I dont think my mechanic ever bothered to connect the temp stuff up when he did the engine conversion. How much is a new temp sender unit?
I have noticed that my ute never seems to warm up even tho I dont have a gauge to tell me if it has or not. Just the other day I stalled about 3 times after driving for about 25mins then about 35mins etc. The driving was 60-110kmh stuff, not city traffic.
So really I need to get the temp gauge working to tell me whats going on.
What is the reccomended temp for the thermostat in the EB donk? I might get a new one just to make sure I have a reliable one. Also I dont run a fan at the moment as there is not a lot of room between the radiator and the pulley. I could fit one but I havent had onverheating probs so far.
This is just a thought but maybe the mechanic didnt put a thermostat in just to make sure it wouldnt heat up. He was/is really dodgy.
Cheers for any help, (sorry about the length)

The old temp sender (XB) would've been in the back of the head on the passenger side. That wire could be the one. The new temp sender is (EB) is on the same side, but up near the thermostat housing. If that is definatly the wire you could try shorting it to ground briefly to see if the gauge moved...
Jase, I wired up the hanging wire to the temp sender at the thermostat. Before I did this I checked the gauge worked by grounding it and it moved up the scale, so the gauge is ok. But when the car was running and when I took it for a drive, the needle didnt even reach the end of the blue. It was just on the start of the blue.
I also removed the EB temp sender and replaced it with an XC one which was a perfect fit because they are the same. I know the XC one works.
I run what I have been told is a GT radiator. Its ****in huge! Its like twice the size of the one in my XC but a little thinner. Assume its NOT running a functioning thermostat and the big radiator would this cause it not to heat up much? I had it at idle for 5 mins but it didnt move past the start of the blue. I also dont have a fan to pull some air thru the radiator so its a bit weird.

is it actually getting hotter? you might have to change senders around a bit they look the same but they do differ. if you dont have a thermostat(or a stuck open one) it also wont warm up.
What you can do is see if you can get hold of an infrared temp gun or else temporarily hook up a cheap capillary gauge and compare what it is reading to what the factory gauge is telling you..You really do need to make sure there is a thermostat though..
Temp senders have varying heat ranges, normally judged by the colour of the band around the top. You may have to experiment with different ones to move the gauge up. Although it doesn't move up much at the moment, when she starts to cook it will (which i hope you never allow to happen)... As long as there is a little bit movement whilst warming up it should be ok.
I have finally got around to looking at the thermostat and surprise surprise the dodgy mechanic HAS cut the guts out of the thermostat. No wonder she runs cold.
Now, what temp. thermostat should I buy? At the moment the gauge hardly reads into the blue! Even after driving through the city and stop-starting it wont leave the blue bit on the gauge. I think I should also buy a temp. sender as the one I am using at the moment is pulled from an XC 6cyl (EB 6cyl motor in the XB), what one should I get (ie. can you match the temp sender to the thermostat so they are in the same range or am I off the track?)?
I am currently running a GT (apparently) radiator which is huge with dimensions about: 800 x 500 x 35 (mm). Is it just trial and error to see if its going to overheat? It currently doesnt run a fan as there isnt a lot of room between the radiator and crank pulley. I could see if the one off my XC donk will 1) bolt to the EB pulley 2) fit inbetween the radiator.
Will thermo fans off any other Ford model fit onto the radiator with out too much drama?? I was thinking that seeing as I have sooo much room on the other side of the radiator (front not engine side) I could mount them there to blow the air thru the radiator rather than suck thru. Would this be a prick to try and wire up to the XB wiring harness? What is involved? Switches, relays etc. I admit to being an electrical idiot, I know very little!
Cheers for your help.

The VK Commodore has a smallish fan mounted on the front of it's rad. with air con. From memory it bolts through the actuall fins in rad.
A wire from accessary to switch relay a wire from battery fused to relay. Wire[relay] to fan. Other wire to earth.. Easy.. Other fan wire to earth.. Auto one sell thermo switches that could be inline between accessary and relay so it's not on all the time..
UTEMAN,
The original thermostat in the 4.0L was 92deg...
Ford part no. ART92G
now I'm no expert but I'd be trying this with the XB/XC temp sender (to match your guage) ..are you still using your originals?
