Went out to car started fine but an odd noise from under bonnet,a quick look showed what was left of auxiliary drive belt doing its best impression of a reef knot!Also pulley at top left[i.e.drivers side]is not in one piece,the grooved plastic bit is no longer attached to the metal centre!Is the pulley a dealer only part or would Halfords be likely to carry these?Also do they generally carry stocks of the drive belt?Apparently mine is the shorter of the two types that were fitted to these engines[3.0 litre V6]or so I'vebeen told.Basically I really need it done by tomorrow as 1]I need it to visit the dragonlady in hospital[she knows I'm not going tonight but she's got others going to see her so she'll not be left out]and 2]the car was stranded on a public car park but I've managed to get it onto works premises[it was only across the road]and we're not supposed to park our own cars on site-the bosses aren't there while Monday morning so I've sneaked it on!Also assuming I can get the bits what tools will I need to replace the pulley/belt? TIA
