Thanks for the reply albatross, this is my first diesel, so still learning.
I will have to get a proper temp gauge to find out what my actual running temp is when the needle is at the halfway mark.
Just noticed that it seems very hot under the bonnet when i first open it...
So it should be between 80-85 deg. The sweet spot that all clearances are designed for.
Where is the best place to get this reading from.
Mine is a 2006 ,D22, ZD30, fitted with intercooler
