need help with changing a timing belt on a '99 626 turbo diesel would appreciate any advice

If you're asking this question then you probably should get a mechanic to do it! No offence, just reading between the lines.

appreciate what your saying, I have a reasonable working knowledge however I cannot find a workshop manual and I was just wondering if there were any pecularities to the mazda that i should be aware of before I started the job. Anybody?

Auto Data sells a timing belt replacement guide phone 978 5629511 or contact your local tool man Snap-on,Matco...etc. they sometimes carry this on their trucks.
