Temp needle sits here

[sternal]

Since the new radiator and new coolent the needle pretty much stays here if I leave if to idle for half an hour or so it goes just before halfway and fan kicks in.

Is this all pretty normal in the madness of T25's ? It used to sit a fraction higher with the old rad and prob watered down coolent from yesteryear !

yes.

...and for goodness sake clean your dashboard glass.

If you or previous owner smoked, the dash gets like that in no time. Not had that since I gave up 3-4 years ago.

Had to remove the clocks and dunk it in the sink with washing liquid.

Incidentally, since I changed my stat, the guage reads higher than I feel comfortable with so will be changing that asap.

I don't smoke don't think the owner before me did either its a rubbish picture taken out of focus with sun glare.

but I will give it a clean !

My needles sitting in pretty much the same position (just shy of covering the LED to the left). Was considering testing/changing the thermostat as I think the gauge should sit at 12 o'c (not 10.30 - 11 o'c). But then again, I figured it's better to be running a little too cold than a little too hot? Might see what happens in the warmer weather..

If the thermostat is on the top of the radiator, I guess I can change it without draining, Will it need bleeding after the change?

I read draining was a two man job as someone has to sit in the cab with their foot on the gas. Can you do it by yourself, by pulling on an accelerator cable near the carburetor or something?

What was the lower rated thermostat? Wasn't it from a golf?

[itchyfeet]

Mine sits pretty much over the LED when hot, I'm not sure if these differences are due to real temperature variation or guage variation between vans

Probably the difference between the petrol and the diesel engine. Mine sits at 12 o'clock or just over.

Golf vr6 according to some posts on here
just ordered one and I'm going to see what difference it makes to my water and oil temperatures (ecp 209440120)

Fitted the 80 deg stat this morning and the needle sits its width lower on the guage ( although I didn't get it stinking hot)
what was notceable was it didn't peak up higher then come down as the stat opened which happens with the standard stat, it rose to dead over the LED then stayed put as the stat opened.

will see what happens to motorway cruising running oil temperture

Easy way to check needle position accuracy

Boil some water, put a thermometer in it, put a new sensor connected up to gauge in the water and as the temp drops make a note as to where the needle sits on your gauge

Thats a good idea but there could be inaccuracy between sensors so may be better to do it with the actual sensor but that means draining coolant.
just so happens mine is drained right now for a new pump so I'm going to do it

80 deg stat....

moved it from 90 deg c position


to 80 deg c position
