Timing belt change - DIY?

Hi folks

Timing belt / big service is due on the time interval shortly, on my 255k '05 TDV6 D3. I'm tempted to try the job myself. Can also pay a garage to do it but I do find working on the car to be enjoyable and think it's a good opportunity to learn.

Is it do-able for a careful and reasonably mechanically-minded home mechanic if I take plenty of time? Or am I being naive and should I just pay someone else to get it done?

Thanks,

Chris

If you are going to do it then change the Oil pump and water pump at the same time, its much easier doing them at the same time, Also check the aux belt tensioner at the same time as these fall apart.

Search the board as Disco Mikey did a write up on belt change and I have a pdf file on how to change the oil pump in my gallery.
Plus plenty of help and reading on the board about the subject.

Thanks Flack. I've seen the guides on here that you and DM have posted for the timing belt and oil pump - thank you as I don't think I'd attempt it without them. Bit nervous about the oil pump. Main question, is it too much for a DIY job for a moderately experienced DIY'er or should I just go for it.

Thanks

Chris

If you are handy with spanners and can follow the guides, then go for it, just take your time, always on hand on the board for help.

for the oil pump, you will need some scafold bar to get the bolt undone.

And torque wrench best to retighen. Not small figures here. It needs to be tight

The guides and the great people on here are your best help! I tackled mine three years ago, never done anything that involved on a car before (been a mechanic for 20-odd years tho). If you're handy with spanners, I support the rest here. Go for it, and there's plenty of advice available from the forum members. Thumbs Up
