I wouldn't mind upgrading slightly to a newer style internal fan alternator, but I'm not too worried about output, as the car is all stock -- are there any newer style alternators that are plug and play? I will probably add the INA clutched alternator pulley as well to smooth out the belt a bit.

If I recall correctly, I will not be able to put the replacement belt on to the pulleys without removing all the mechanical cooling fan bits (I hope I'm wrong?) so I will probably replace the water pump and radiator as preventative maintenance.

I'd also probably like to upgrade the water pump pulley to the smaller one from the OM606 for increased cooling capacity -- summer is coming. Any tips on any of the above? I replaced the tensioner, idler, fan and clutch (with the plastic version from the later diesels) in 2015.
