i think i know the answer to this one ,but looking for agreement from others.
My t25 1.9 diesel runs hot.
The temp gets up to just past half way so all of the red light is visible and stays there.
But this is at the point where the electric fan cuts in.
Once this temp is reached the fan cut in and out constantly till engine is turned off.
But if i put the heater on and put the fan speed to number three the temp drops and the rad fan cuts out.
I have already changed the thermostat and bled the system .
I recon the rad is knackered as it only gets hot at the bottom.

You could be right ... have you taken it off and had it blown through ?

Not yet , not looking forward to the air locks in pipe when replacing rad.

I thought the airlock thing was a myth?

Give it a good flush out,refill and bleed it . Its probably just full of crud.

Hi it could be worth replacing the rad as it is probley years old and sounds like it knackered ! also its a lot cheaper to replace than a cooked engine and the aaz 1.9 td dont like running hot so i ve read ! gsf do one for about £100 .00 brickwerks do one about £ 160 but good qualitiy not to sure about gsf seen one looked ok but thats all could say about it ! hope you sort it .
