I'm a little confused re. which sensor is the one that is so famous for failing in the coolant circuit (temp sensor). Is it the one on the back of the 'spider' fitting just under the vac. pump where the coolant glow plugs are, or the one in the hose coming from that and moving forward towards the radiator between the head and the oil filter houseing?

It's the one facing backwards with the 2-pin connector on it. It's the one just under the Vaccum pump.

The other hose next to the oil filter housing is the Thermostadt.
