Depending on available space I'd go straight for the stud extractors. Mainly because I have a set in my tool box...lol

Never had much joy with stud extractors.  The bi metal corrososion will have welded the stud in place, try getting the engine hot beofreyou remove it as Ali grows at twice the rate of steel, also put loads of WD40 on it the night before.

Same thing happenned to me lasy week , i tied everything to get it out but eventually i drilles it out but damaged the original thread  :rolleyes:

Because of this the original bolt would not grip so i drilled all the way through the fixing and added a tapped plate to the rear of it, works fine and it wont go again.

Also be careful when buying belts as i bought a replacement and fitted it and then it happenned , turns out there are two belts for my model and the second one is 25mm longer so putting less strasin on the tensioner !!!!!



hope it helps

Cheers for all the replies.

I've managed to fix it! Yay!!  :D

Because of the limited space I used a cordless dremel, used an incredibly fine milling bit to "centre punch" the centre of it and then either side of the centre.

I then used a 3mm drill in the Dremel to drill three holes across the middle of it about 2mm deep. then joined them together.

Then simply used a screwdriver and a lot of force and swearing and out it came!  92p for the replacement and straight on :)

I've took the fan off too, don't really need it with the weather and the fact that 7 blades are smashed off it means it would have been out of balance.  I'll probably put an electric one on it when it gets a bit warmer.

Now just need to fix the PAS leak for the MOT...
