200TDI serpentine?

What would be the advantages?

I assume a serp belt can perhaps transmit more power? Are they quieter? Obviously you have just the one belt, which could be seen as an advantage, but then it involves tensioners etc. too.

I guess they must be better overall, as all modern cars use them.

The main advantages would be strength and having a tensioner I suppose. I just had 2 belts go on me last week and found a chunk out of my crank pulley (which as it turns out was not the cause, it was a leak of coolant onto the belt causing slipping) this just had me thinking about it and I know many US engines have conversion kits so I was wondering.

Agreed the 200tdi belt designer was a clear either stoned or Mildly miffed or both when thinking up such a system.

But it is very simple and even when the belts get loose and slip they do still work. 300tdi however if the tensioner goes/starts to like what has happened to dads then you have a much more urgent issue than a few loose belts and an awkward adjustment. I think for toughness I would take a 200tdi setup, for everyday refinement then yes a 300tdi style setup does have the edge.

One of a number of problems I'd had with the Micra recently is the pulley dropping off the alternator. Now I know the car has done almost 34,000miles now so I shouldn't expect it to last forever :huh: but the pulley I'm told has a one-way clutch in it to protect the alternator from the pulsing effect caused by the flat multi-vee belt bouncing and the automatic tensioner. The drive belt isn't even that long, but then the engine is built by renault.

Funny thing is my old Escort has a single vee belt mounted on a slotted bracket and that's still working, 31 years later.

The main advantage is no more faffing about trying to correctly tension a belt by moving your alternator in a slotted hole. The tit that invented that should be shot.

I don't mind it, I built a little bolt tensioner to adjust my alternator belt, nice and easy now :)
