Toothed Or Smooth Fan Belt?

[TakeLifeEasy]

Our Bus is 1971 left hand drive and the fan belt on it currently is a toothed fan belt. I ordered a spare fan belt a while back and was going to fit it today and realised it did not have these teeth and was smooth all the way round (v shaped). Is there a difference between the two and did I order the wrong one? I have been reading this thread but non the clearer -

Smooth is best, the toothed tend to wear to the strengthener then slip.

Damn, I should have swapped it over but I was worried it was the wrong one! Still Ill keep it as a spare for the time being.

Many thanks again!

The toothed ones tend to be for dynamo/generators and the smooth ones for alternators, they are slightly different in both width and length.

It doesn't make a blind bit of difference, as long as the belt is the right length and width either will be fine.

Many thanks for the responses, very much appreciated. Just ordering another one as a spare!
