Does it do it on petrol and LPG?

Just wondering if the LPG fuelling is a little lean.

Could it just be a case of an air lock with low coolant, fine with low revs / small throttle openings, but give it some stick and rev it a lot more, the sudden rush of coolant in the block going to the back of the motor could give the sensors a false reading? maybe?, I had a very similar problem 3 years ago and that's all it was.

Okies .. not the waterpump then :(

But why does it only run hot when towing and booted to over 3500 rpm ?? and cool very rapidly when the rpm drops ??

If it was a blocked radiator, either internally or externally, giving poor heat transfer, then it would take a while to cool I'd have thought ??

The car towed to The South of France 2 years back with much heavier work, and to The Lakes this year without any hiccups. I don't see it silting up that fast ??

It had a coolant flush/change in May 09 just after the thermostat change. (15000 miles) so it might be worth doing another and seeing what comes out I suppose... :(

Puzzled of Wiltshire...   :-/ :-/

I'm not towing, bet it happened to me after climbing a mountain hill and stopping.
The rad was quit dirty and the only thing help is to dismantle and clean.
