Changing belt at same time as radiator,any advantages/modification?

if I want to do a R & R on the serpentine belt while changing a radiator with a repaired neck,are there any modifications of the below technique,or is it the best time to do it?

What brand does the Fastlane sell(belt,I mean ) or should I get a real MB stamped belt?

I'm not sure how many instructions you'll need, but here's one more.
Remove the Ignition cover from the distributor cap.
Remove the 2 retaining clips holding the shroud in place and lift the shoud up from it's positioning slots.
Lay the shroud back over the front of the engine.
To remove the fan/clutch you will need a special allen socket wrench and an anti-rotating bar to keep the fan from rotating while you loosen the retaining bolt.
These can be purchased from many sources.
At the belt tensioner, loosen the 19mm headed bolt 1/4-1/2 turn.
Turn the setting pointer to the left and position it to the first graduation mark(arrow).
Remove the old belt.
Fit the new belt beginning with the belt in a "U" with the ribs or flat side in position.
1. position the "U" around the tensioning pulley and proceed in sequence
2. top of crankshaft under to the right
3. from the tensioning pulley over the fan down to the left
4. under the alternator pulley up
5. over the idler pulley to the right
6. over the water pump
7. around the power steering pump pulley
8. across the A/C clutch
9. finish at number 2.
Turn the tensioning nut to the right until the pointer is positioned to graduation mark 7 with A/C or 5 w/o A/C.
Tighten the 19mm bolt to 75Nm.
This presets the automatic belt tensioner.
Replace the removed components and you're finished.
I know this is long winded, but it will keep you from making a mistake.
