| Post subject: | Loose fan belt!!!! |
Hi everyone So it seems to be that my fan belt keeps coming loose. I'm assuming it would be the alternator maybe moving? I don't really know where to go because all the bolts are tight and the sleeve in the top bracket is firm.. It's gotten sorta progressively worse, could go a few days of driving with it tight, then a day, half a day. Now it's just done 20km's and needs adjusting again or it squeals! argh please help me Thanks James |

Is the 9/16 nut that holds adjusting arm to the engine front plate tight The alternator is held on with three bolts and one nut. Are they all there. |

Yep they're all there, and they're all new bolts/nuts And yes the 9/16 nut is done up nice and tight Scoop wrote: You havent got worn pulleys have you? Belt going in the V to much. Well I'd hope not, the engine is new, the water pump pulley is new and it's a new alternator |

Is it actually going loose or is it just squealing a lot? Try rubbing some soap on it to stop the squeal. |

Are you running out of adjustment? Maybe a dodgy belt and is stretching???? Just a thought..... |

Do the pulleys have the same section to match the belt. Can you compare them to the old ones. |

The only thing left is the belt. Is it a good quality one from a good manufacturer |

I would buy a belt from Oz. Take a pulley with you and the belt with you for the length. I am not a fan of cogged belts. Find a vee one. Fingers crossed it sorts your problem. |
