any ideas?

the fan belt slipped of my vito van about 2 wks ago & the mechanic put it back on...

but since then there is a loud screeching sound when I first put the van in to gear & drive - the screech last about 10 seconds or so then goes away usually when I get to third gear....

the engine also overheats when the van screeches then returns to normal when the screeching stops....

as I said it only ever happens through first & second gear - when I turn the the engine on - u can hear a very low screech but once I get me bite & release the clutch she squeals like a pig...

when the mechanic put the belt back on the belt was in good condition.....

this is for taking the time to read this....

Sounds like a bad pulley on one of the accessories or a bad tensioner.

thank u mate.......when I first ignite the engine it's like a low whistling sound - then a big squeal when I get my bite in first gear & up to second.....

another thing - sometimes my horn works & sometimes it doesn't - u have any ideas on that?
