Tony,

Your radiator fan appears to be working normally. I hesitate to say any more than that, other than wondering whether the weight of your caravan is within that permitted to be towed by your car. I feel sure that you'd have checked that.

Simon, I reckon I am within the limits ok, kerb weight for CDti shows a range of weights, I have gone for 1585kg, the caravan is 1420kg which comes in at about 90%, ideal recommendation is 85% but the extra 5% is not excessive.
In every other way the outfit is superb, the car pulls like a train and is very stable, i consider it to be a superb towcar. I think that I am going to 'suck it and see', in a couple of months I have a 1600 mile journey back home over quite varied terrain, so will see what happens. Putting it in context i have covered 1960 miles with only these two incidents. I was just struggling to get my head round the logic of what caused the problem. Thanks again for your input. Tony

Do you have a top hose thermostat mod? I have heard these can sometimes cause issues with towing.

Only early car (up to around 2001) have the oil cooler in the LH wing, later cars have a oil to water cooler. If car has fog lights then later cooler is fitted.

I am reliably informed that if the ATF does go over temperature, the IPK flashes up a message as well. So back to square 1

This is not advisable since the slow speed relay is not rated for the full motor current.
I know, but stuck in Portugal without a slow speed fan, tell us what you'd do.

Yes, you did suggest it as an emergency measure. The problem is that such temporary modifications have a habit of becoming permanent so I thought it best to sound the warning klaxon so that everyone is aware of the risk. But I take your point; yes I would do whatever was necessary to get the fan working.

Simon

I think the OP stated that the fan was working correctly .

With a cold engine if I turn on ignition and press demist the rad fan starts running and goes off when |I switch off demist. Likewise the same happens when I switch on Auto on Aircon and fan goes off when I switch to econ.

The aircon is working ok
AFT fluid up to level?
So system blockage or dodgy thermostat. Time for the dishwasher tablet treatment?
