Nissan Largo Friends

Hi newbee from Gloucester

I have a 1998 R reg 2lt CD20 engine largo and need a new fan/alternator belt but am having trouble finding one that will fit got one of ebay was told 100% will fit but its to big anyone no the size or part number

alternator belt is 13x1125 vbelt m8
Gsf online had hundreds in stock

Thank you for telling me the belt size after months of searching and trying 3 other belts which were all the wrong size it was great to be able to walk into Gsf Gloucester and back out again with the belt as they had them in stock, no more squealing when I start the engine.
