bit wet maybe?

Went off roading today, lot of fun, only got stuck once but will post bout that, went through quite a bit of water, not massivly deep but at the bottom of decents etc, on the way back it really hammered it down, roads a bit flooded, but all well getting back. Come to drive it later though and there was a squeeling when driving off, sounded like fan belt slipping, but at one point cut out, any thoughts? started again fine, I'm just thinking maybe got a bit too wet / damp. Sort of wondering if it was to do with not charging?

Cheers

Could indeed be caused by a lot of water and the fan belt that has not enough tension.
Take a look at this belt if it's not too loose.

i drove down a river the other day and my belts were screaming abit no cut out tho
