Hi,

I have a Fiat Ducato MultiJet 100, 2.2, 2008.

The engine temperature has a hard time reaching operating temperature. And when it does, it reduces if i don't drive 80km/h+. It's like it receives coolant all the time or something. The thermostat is changed without a result. I change the EGR and will see if that does it, since it was blanked off with an EGR plate before.

Anyways, i have a new coolant temperature sensor which i ordered a while back, but i have not changed it. I looked at a picture of this engine and compared it, it seems to be there (number 7)


I am wondering two things:

1. When removing it, does a lot of coolant leak out?
2. How can i unattach the nut? It seems to be very close to metal parts/the engine on both sides, i can feel the sides of the nut but it seems difficult to put a tool there, ideas?



Thanks

/Jonathan
