My time to ask a question.

The marea and bravo 1.9 JTD engine is very similar so.....

For a while now everytime i started my car I would get a tweeting noise coming from my auxilary belts area until the car warmed up after 5-10mins. Anyway i decided to have a go, once and for all to try and fix the problem for good.

Common causes are usually the adjustable tensioner, crank pulley or fixed idler pulley. So i changed the adjustable tensioner and the idler pulley only to have solved part of my noisey morning start up. Basically the noise has reduced significantly since i replaced the idler pulley (bearings shot) but the tensioner i replaced was perfectly fine but replaced for good measure.

I know the crank pulley and air con is fine and silent but under futher investigation I noticed my alternator tweeting when the belts are going round. Its not as bad as it was but i want to get rid of any of the noises i once had. Pit as the alternator itself is fine and works.

So i was wondering how easy it is to replace the alternator on a JTD. Haynes doesn't cover diesels, the porters manual has 3 small sentences on the matter making you think its extremely easy, so was wondering if anyone here has had a go at it. I know theres very little room to do anything in there but any advice welcome.

I've already sourced a new alternator, now all i need to do is buy it and fit it. Then hopefully i will just have the diesel clatter in the mornings and no "tweeting" except for the birds.

Have replied in your other thread mate.

have done a hand full off them bud they are a bastard the best way is to remove the drive shaft and get it all from under neth and pull it out through the whole where the shaft goes prepare to cry your eyes out though

might be of help + few pics aswell.

Didn't think it would be as easy as just removing two bolts. Thanks for the link. Gonna weigh up my options and see whether i should do it myself or save the blood, sweat and skin and get a garage do it.

Thanks for your replies and help.

Well good news i finally sorted out the annoying squeel.

Panic over, it was the auxilary belt. Changed it and now the start ups are silent (well except for the diesel clatter).

Comparing the old and new belt there was a noticable difference in size. Further investigation i found the old belt to be 35mm longer than the new one. The old belt was for a TD and not a JTD.

Anyway got the new belt on and im very happy again.
