First question:
Read through the forums, and looks like most folks agree that 119 should be running hotter than 103/104. Why is that? I thought 104 will be running hotter since 119 seems to have a lot more room under the hood than 104.

Second question:
Compared to my E320, E420 takes much longer to warm up and often sits at 80 degree mark for extended times. But, when it starts creeping up (idle traffic, low rpm etc), it seems to hover around 100 degree mark which most posters deem ok. So, is the first part expected or seen on these cars?

Third question:
What's the recommended source for fan clutch? Most places (pelican, ahaz etc) have either MB for 800$ or URO for 80$. Don't like either option.

Thx much.
