The new water pump had a metal impeller. I suppose I can start stripping it down tomorrow.

Can these heads be skimmed? I dug up this thread here:

QuoteRed light came on with a coolant warning on the LCD readout.Which red light - the overheat one?
Looks like the car is dead then.
After all the trouble I went too what with changing the gearbox, chipping in addition to what resources I've thrown at it trying to fix the bastard thing.
The one in the temp gauge. Red light of death then?
It has come on once before though towing a full 3/4 trailer and then I was just as quick in shutting her off and coasting to a layby.

The thing is though, it wasn't showing any signs of such.
You may remember my old thread about the constant running hot snag. In my attempt to solve it I replaced the water pump, stat, rad, several switches, flushed the block etc etc yadda yadda.
At no point was there any evidence of impending HG failure. No mayo on the stick or around the oil filler cap, and no loss of water. Till today where I assume the car got fed up of a constant water temp of 95'c hence spat its dummy out.
Is there a thread on here for the 2.5TD HG replacement? Also, including parts and head skimming - ballpark figure wallet wise?

'New' rad turned up from a company called 'Applied Radiators' and they are taking it back as well as it's turned up with a few too many dinks on it with two large fresh cuts in the bottom and top sections.

New rad ordered (£191 inc VAT! 
) so we'll see if that makes a difference or not.

Right then, my next job will be to sort a switch out for the intercooler fan and replace the seized rad fan.
I think I'll be best to replace the rad anyhow as the symptoms are as if the rad just isn't big enough.
Put it this way. Car behaved itself with it being sat at 80'c no matter how hard she was pushed. I go away for 4 months spotting penguins and she first nearly overheats but with a good flush she doesn't overheat but she does run to warm.
As if some of the rad is still blocked?

I don't think I have an intercooler on my car so the 2 fans at the front must be aircon?

I've not been brave enough to try that out yet. I want a fully serviceable cooling system first.

Even though I cleaned out the rad to the best of my knowledge could it still be Fubar inside?
It's as if the rad is just not man enough to cope with cooling the coolant down so maybe a rad change would solve the snag?

Well if they'll not do anything there isn't any point in changing them. What about Tech 2 plugged into the Ecu to confirm if I'm being lied to or not by the gauge? How do I go about getting hold of one?
I can't see any more options really as I've changed pretty much everything in the system.

So with my constant running temps of about 95'c it's actually running at 105'c-110'c?
So that said, surely it should have blown the HG or something by now?
Wheres the sender unit for the gauge? Think I'll try swapping that.

I still have this snag so when I got back from work I had a quick look under the bonnet. Now as it's running hot, after a journey, the electric fans are heard to kick in. So, looking under and through I noticed only one was operating. After the fans stopped (and with the engine off of course!) I had a quick poke about with my keys to find the drivers side electric fan is seized.
Could this be the cause of my running temps?
Is it a bumper off job to change?

Temps still rise to the 95'c mark. It does take a little longer to get there but on my 20 mile run to work it eventually did so.
I suppose I could use an airline at work to blow through the 2 rads. Seems to be a little bit of grass collecting but nothing I would have imagined to cause such a drastic difference.
End of Feb 2009 it wouldn't budge past 80'c. I go abroad for 4 months where the car remained static and I come back to this overheating issue.
