Nope... Because until it generates enough heat to open the thermostat the coolant is recirculating in the engine anyway.Quote:

Mine gets above blue after 3.5 km, and reach the optimal temp around 6. New Thermostat, off course. Before, never gets there until 10 km
Diesels do not waste a lot of heat, so in cold weather they take a long time to warm up.
A radiator muff would probably help, even though the radiator is not doing much until the thermostat opens, as it would reduce the cooling airflow over the engine.
With my Isuzu, I run a radiator muff in winter, and despite this plus a (fairly) new thermostat, the engine temperature still drops below normal in cold weather except when working hard.

I must say I've been wondering about this too, my TD5 Defender seems to take about 10k, my Dad's TD5 Disco takes maybe 4k.
Perhaps I should buy a new thermostat and see if that makes any difference?

Well, as I told you, there were a great difference between before and after fitting a new thermostat.I think the old one was already leaking internally, so as soon as the engine started, there were water circulating through the radiator, it doesn't let the engine warm up properly
i have a new radiator an new thermostat id say 3 k on average to get upto operateing temp but i dont live in town so once i hit the road its straight to a 100 , i normally let it idle for 2/3 minites b 4 i go
