Does your van have a fan belt cover?

Yeah, and stops it getting totally drenched when it's raining. Only a shield not a cover.

So far no rain, so can't confirm an improvement as the squealing would always start whenever it rained (and then go on for a day or two afterwards!). Will let you know more after a soak!

Well, that was a good soak. Floods an all!And can confirm that squealing has stopped. Yippee!!

Still tries to squeal when I steer on full lock but I guess that's something to do with the power steering - a separate issue to the awsomely loud squeal after rain... that has now gone!
