helpfull answers please, How can I test the rad without disconnecting tranny pipes.
Aircon is RIP
you won't lose much atf undoing the tranny cooler (though still worth rechecking level after.

It is possible to infrared sensors to check rad if you really don't want to remove.

Well I have to drive 300 miles tomorrow so I'll see how I get on.
I had ordered a new pump & stat. But doubt they will help.

If the rad proves OK, you may need to do an oil flush

Now why would an oil flush help.
Car is now on 150k I got it at 114k full history but no record of the 5k oil changes. It runs strong & silent.

Taking on board The Boy's theory regarding the oil-change, I did mine.

This included an oil flush, refilling with Vx 10/40 semi-synthetic, and a filter-change. I've noticed a minor running temp change - maybe a degree or two lower.
My own view is that Vx's recommended 10k intervals during the early stages of the engine lives has contributed significantly to the problems now being encountered. My tractor gets an oil/filter change every 3k miles.
Let us not forget that many of these engines are now over a decade old, and have often accumulated collossal mileages.

like many engines, the td uses oil and oil jets to assist with cooling as well as lubrication.

The oil jets block sometimes, causing lack of cooling.

Remember, oil change interval is 4.5k max (not 5k) ;)

I'm not in city traffic too often so I figure 5k changes ok.

Yep - engine oil and filter every 3k religiously ...... !

Before starting this regime, do an oil flush.
You'll be doing the engine a  big favour in the long term. I use Vx's own brand 10/40 semi -synthetic which is very favourably priced.

If the rad is cold it would suggest a lack of movement within it - my complete system is warm when i stop and touch the pipes or rad.

If you need a stat I have a new Vx one I purchased but didn't need - see http://www.omegaowners.com/forum/YaBB.pl?num=1212092549

As said - 4.5k MAX - mine always gets done at 3-3.5k with Vx parts & oil.

4 x 5l oil is £29
4 x Filter is £20

That lasts me about a year-ish.

I changed the pump, No difference. I changed the stat, not tried it yet.
The bulk of the water flowing into the rad seems to take a short cut thru the small electric pump under the expansion bottle.
What is this for? it comes on with the electric fans (top rad switch) (bottom switch doesn't do anything.
Can I crimp this pipe to force the water thru the matrix or is it related to the tranny cooler?

The rad should be an easier route for coolant, hence the other bit shouldn't affect it.  If the rad is blocked, then its fubar

It looks like you're right.
What is that electric pump for? sucks out of bottomof rad batt side , returns top MAF side?
