T-8 Timing Belt

[charlie h]

Hi Guy
I was thinking about changing my timing belt on my 2003 T-8 . I use it year around , she has some hours on her . What is the recommended time to change it and is it much of a job to change out ? Is the T-8 a zero clearance head ?

Thanks for your help
Charlie

Timing belt needs to be replaced every 1000 hours.
