DONT run it hot or you will crack the cylinder head on a TD5.
Yu'll have diesel in your engine oil and all sorts of problems.
Can you say expensive. Dont ask how I know but trust me I do.

You said there is no coolent loss so it wont be the expansion tank cap thenIs there a chance its the expansion tank cap.
I think im going to change et cap , thermostat and waterpump then hope for the best

If you do those things you can be 99% sure you won't need to hope for the best because you will have done the best.

Or a blocked radiator
Sweet, as in the fins blocked with mud or an internal blockage

I'd take the rad off and give it a good clean with a hose.
Worst case a new rad is £80 from Paddocks.

sorry to kidnap the topic but just a quick question...
my 52 td5 110 van when goin down the motorway full tilt will flick up to the red and the engine will throttle right off and then it will go back to just below half again and it will start to accelerate again... bit annoying when overtaking as it drops to 50 :O
thanks for any advice

Try changing the coolant temp sensor first.
Are you suffering any loss of coolant? If the temp sensor doesn't work then I would suggest a new thermostat and expansion cap.

coolant sensor is about £16. Thermostat is about £15. Rad cap is either £4 or £8 depending on year. MAF is about £40. Unless you find it's taking forever to accelerate it's not the MAF.

Glad you sorted it.lloks like it was mud on the inside of the rad under the cowel and between the intercooler

The radiator is a "WATER TO AIR" heat exchanger. It is not really a "radiator" at all - it is a heat exchanger at best, and a convector if you must.
Water can contain more HEAT per unit mass than almost any other substance, perhaps four thousand times as much as air.
So, we need several THOUSAND times as much air as water to carry away the heat from the engine coolant- and that means a lot of air has to pass straight through the fins of the radiator, air-to-metal, and not air-to-MUD!
I just went out this very minute and air-jetted the radiator fins of my 2004 Disco TD5. Quite a bit of crap came out, so it was worth doing.
Off-Roaders should be very careful to clean their rads after every trip.
30 seconds if coolant failure could cost any of us a whole engine.
OUCH!
