I'm sure we'll have all experienced it.
I've always referred to it as a dry timing belt but I suspect it's the ancillary belt (the rubber one that does the a/c compressor among other things. you know when you first start the engine you get a squeal etc. I've tended to pop the bonnet and give it all a liberal spray of WD40 but suspect there might be other / better advise out there?  |

You're disguising a bearing failure on a pulley.....

A new belt from Land Rover is only about £25.
If they've been contaminated they can polish up on the backs and slip a bit. They're supposed to be good for 10 years, but it might even have stretched a bit. Personally I'd order a new one, and whip the old one off, while it's off spin the pulleys by hand and check they're all quiet. If you've been adding WD-40 on a regular basis it'll eventually not do the belt much good. |

WD 40 will make it slip more and more, it's supposed to do the exact opposite!
Change the belt over, and clean all the pulley mating faces problem should be gone. I changed my belt over at 55k, really because it was easy and very cheap. I occasionally had a squeak on start up, not any more.  ⭐️⭐️God Bless the USA 🇬🇧🇺🇸 ⭐️⭐️Last edited by custom90 on 26th Feb 2018 5:49pm. Edited 1 time in total |

Exactly. Spraying WD-40 on it is just a diagnostic aid really. If you spray it on the belt and it goes quiet then you know the belt was slipping.

aha. not looked yet but I'm guessing a simple job too? Nothing needs to be held in place like a timing belt right? |

No, pretty simple just the tensioner needs slackening off.
No need to remove fan or anything like that. Obviously isolate the battery first. ⭐️⭐️God Bless the USA 🇬🇧🇺🇸 ⭐️⭐️ |

There's a sticky in the TDCI section about it.
http://www.defender2.net/forum/topic47382.html It's easier with the fan removed, but if you don't have the tool to remove the fan you can do it with it in situ. |
