Hi..there thanks for your reply..

Ok..these 2.4 d5 are timing belt engines - so particular checks would have to be made to ensure the belt hasnt actually worked its way into the lower crank sprocket that the timing belt is on as this could cause the timing belt to snap or jump teeth if turned over if not already - if that's the case then the timing belt needs replaced and do not turn the engine over until its been done..

the problem with the auxillary belts wrapping around the lower pulley means you need to get proper access to the lower crank pulley to start cutting it away - by removing the drivers tyre - the protective plastic under tray - to get a proper look at the damaged belt and how far in its got by cutting bits of the belt off the lower crank pulley which you need to do with a good sharp stanley blade and snip pliers..until "all" of the belt has been removed.also check the grooves on the pulley for burning incase the belt has left a residue behind..which you need to clean off with a wire brush,brake cleaner etc...once the damaged belt is off then inspect carefull the lower timing belt cover for any damage..if theres no damage then you may of got away with any damage or that belt working into the timing belt.. Normally what most garages do is remove the centre crank pulley bolt and remove the entire pulley to get that belt off..so that could be something to maybe phone around for - maybe a local mobile tech with a good impact gun to get the pulley off..It really depends on how far wrapped around the belts got if you can pull it off with your hands or un wind it then fine you can do that - but make checks to rest of the pulleys that belt runs to ensure these arent the cause for the belt to go in the first place ie: any siezed/damaged or loose pulleys.all should be easy to turn by hand bar the crank pulley..before you re-install a new belt on...I do hope this helps
