Low/Contaminated coolant
Thermostat
Viscous fan
ECT sensor
Restricted air flow over the radiator
Check the coolant level and condition. Check the thermostat and rectify as necessary. Carry out a cooling system pressure test. Refer to the relevant section of the workshop manual. Check the viscous fan operation, make sure the viscous fan rotates freely. Check for obstructions to the air flow over the radiator.

topping up coolant
On this point I know you have to add anti freeze pre diluted to the correct mix, will any red antifreeze be the same or as long as it is the correct spec from the manual will that do?Arctic Frost Discovery 3 TDV6 SE, Active Rear Diff, Adaptive Head Lights, Tow Pack, Ebony Leather, Roof Rails, Mantec Guard.

Not sure what RED antifreeze you have but mine is an XS on a 57 plate. Only dealer serviced and the anitfreeze is bright orangeHONI SOIT QUI MAL Y PENSE

I had a chat to my stealer and a radiator specialist (different organisations) after buying my D3 and they said in the strongest possible terms, not to and any antifreeze unless I was positive it met the exact specifications. I was looking for some to carry in my "remote trip" box, but both gentlemen said that I should use only distilled water to top-up any shortage. The reason for all the fuss, so I was told, is that the engines (I have V8, but same thing applies to DTV6) use a wide and differing range of alloy steel in them. The antifreeze is more importantly an anti-corrosive. Putting in any different antifreeze mixture will probably neutralise the anti-corrosive and some very-expensive and difficult-to-replace component in the engine will probably corrode very quickly (stealer said an analogue is putting petrol in a diesel engine, or gear lube instead of engine oil). I could only buy the correct antifreeze in a barrel, but it starts to lose its essential properties when exposed to air.
Based on this advise, I once had to top-up with distilled water (turns out it was the faulty sensor in early-model D3s), and at the next service had the dealer test the anti-freeze concentration and add a bit more (he had to drain about a litre of coolant to get enough space to do so) anti-freeze to bring the mix up to spec. Clearly the compromise inherent with the delightfully effecient and fun-to-drive engines we own is that they have to be cared-for and fed only the correct nutrients.Jim Dowell - D4 HSE TDi, 12,000 hydraulic winch & hidden winch mount, MTRs, TyreDog, Traxide 2 x aux battery system, fixed air compressor, Dolium roof rack, MitchHitch.

Sorry to revive an old post but...
My 06 2.7TDI has suddenly developed a fault (faulty sender?) The water temp shows maximum even when cold, and when starting you can hear a wooshing presumably from the fan trying to cool the cold engine.
Any clues. or anyone know whee the sender is located? looks very crowded under that bonnet.
Thanks
You always get a whooosing noise when starting from cold, until the oil in the vicous coupler has flung out and released the clutch.
I'm not 100% sure where the sender guage is - there is one sensor on the pipe at the top right (Looking in) of the engine when you take the cover off.Mark.

Not an uncommon problem (I have had it too) and the sensor does not cost much and takes seconds to fit. Oh and it is the sensor on the RHS of the engine at the front, so easy to get to too!
The instructions:
WARNING : Since injury such as scalding could be caused by escaping steam or coolant, do not remove the engine coolant temperature sensor while the system is hot.
CAUTION : Engine coolant will damage the paint finished surfaces. If spilt, immediately remove the coolant and clean the area with water.
1 . Disconnect the battery ground cable.
2 . Remove the engine cover.
3 . Disconnect the ECT sensor electrical connector.
4 . Remove the ECT sensor.
Lift the tang and rotate the ECT sensor anti-clockwise.
Remove and discard the O-ring seal.
Installation
1 . Install the ECT sensor.
Clean the component mating faces.
Install a new O-ring seal.
2 . Connect the ECT sensor electrical connector.
3 . Check and top-up the coolant.
Clean any remaining coolant from around the hoses and pipes.
4 . Install the engine cover.
5 . Connect the battery ground cable.Land Rover - Turning Drivers into Mechanics Since 1948
