i have a problem with my 200tdi defender over heating. It has always had stable temperature whilst i have had it, but today it is running almost into the red. It is an original factory fit 200tdi, not a conversion.
The top hose gets hot, the bottom hose doesnt get warm at all. the viscous fan is spinning slowly when i lifted the bonnet and it was approaching the red temp sector, i dont know how quickly it should spin.
there is no ticking on the engine, and the oil is nice and black. no mayonaisey muck in the oil or signs of oil in the water. when i got up to 40mph, it didnt seem to cool the engine. I do an 8 mile journey from work and the last 2 or 3 were starting to get to 3/4+ on the white sector of the gauge. Coolant level was fine. I opened the expansion tank carefully whilst it was warm, and it seemed to be pressurised.
am i correct in thinking that the thermostat has failed in the closed position?
The heater still doesnt blow warm, but i think this is likely to be a different issue.
