DIY: Coolant Exchange Pipe / Valley Pan Replacement. e70 n62 4.8L

Thanks for the QUICK reply. I will give it another try later this week (too late today). The tips are very helpful.

My task is to replace the belt (the alternator one), the deflection pulley and the tensioner. Any tips on removing the bolts of the pulley & tensioner? I think they are 16mm bolts and hopefully removal is straight forward.

Cheers ...

The deflection pulley has a cup placed over the bolt that holds it.
The tensioner pulley I dont remember.
Here are some parts images.
