I have a problem with the cooling system in my XG ute , I think. The radiator was redone about 12 months ago, and the Head gasket was replaced around 2 months ago, but I'm having a problem with temps still, coming up the new SE Freeway the temp gauge gets right up to the red zone, this is even without a load on back.
Admittedly it was 40deg when this happened but the cooling system should be able to cope with that I thought.
I also had the temp gauge creeping up on the drive home tonight. Anyway my thoughts are this.
1: Take Radiator out and make sure there isn't too much crap between Rad and Condensor.
2: Check Ignition timing (car does feel a little sluggish).
3: Remove Water Pump check and replace if necessary.

Not sure what else, thermostat should be OK only about 6 months old, however it is a AU thermo, and I'm not 100% sure of the working temp range in comparison to XG, anybody got any specs on this?

One other question is does anybody know if its difficult to fit electric fans out of a EF (?)

First thing I would do it fit a genuine thermostat to suit that car, not an AU one as it may have small differences that are not obvious. My brothers EB2 had a wheaty packet thermostat and it used to get hot all the time, replaced it with a motorcraft and now it's as steady as a rock and never gets past half.

I had a heating prob about a year ago. Apparently Ford put sand in there blocks for casting, which fills up the radiator. bought a new one, used a sock for a month, now she runs real cool.

Now if you've done that.

I also pulled of the wter pump. What waste of time. It was perfect. I could be that. It wasn't mine.

Stick a temp gauge in the overflow bottle. Just to check it's getting hot, it could be just the gauge!!

Jesmol,
Hope you solve the problem mate. Let us know how it goes.
About thermostates how many different types does ford stock? I bought one from ford dunno what it's off but i specified an EL one and he said that the ones ford stock are the double acting thermostate. IF i get a chance to duck into the garage i'll post the part number.

So i'm guessing ford stock thermo's for EF-EL, EA-ED and AU's.

I fitted the thermostat from Lynas Valley Ford last Night and am glad to say my apperent overheating issues have gone away. Drove up the SE Freeway today at about 35deg and gauge only got to halfway. I'm sure most cars would experience some gauge movement under these conditions.
Anyway the "double acting thermostat" that the Ford guy told you about is just a thermostat with a "foot valve", these valves shut off the Heating circuit when it gets too hot (ie thermostat opens too far), this then direct all the coolant into the motor and bypasses the heater core. Not sure of the theory behind this, whenever a car overheats I always put the heater on wind wth windows down and let the air flow through.

All car makers use sand in the casting of engine blocks, Ford just do a horrible job of cleaning it all out.

Ford dosent make the mistakes.

ITs the 12 year old aprentice's they employ in the factory.

Ha, Not much use in my XG.
The bloody heater core has split or something letting all the coolant out - currently bypassed.
I haven't fixed it yet as I'm too scared to pull the whole dash out to get to it (hey, it's still summer anyway).

At least you have something worthwhile to take the dash out for, I spent three days taking the dash out, pand putting it back in my Dads XF, all to do up a single screw that had worked loose in the fan housing and was causing a horrible rubbing noise that you couldn't put up with. All this done during a 40 deg hot spell in Adelaide. Woo Hooo.
And then there was the time we fix a mates Escort panel van with a seized spigot bearing. 1 day to take gearbox out and replace bearing, 2 days to work out motor need to come out, 1 day to take motor out to refit gearbox. WHO DESIGNS A GEARBOX THAT WILL COME OUT WITH THE MOTOR IN PLACE, BUT WONT GO BACK IN??????. BLOODY POMS (still mentally scarred over this whole exercise)
