1998 Terios timing belt advice

Forum: 

Hello all,
With my Terios having agrey area in it's service history I've decided for peace of mind to change the timing belt. As I can't find a workshop manual it doesn't look too bad to do and from looking it has a plastic cam belt cover so (as I've read here) must have a belt. My questions; is it a reasonable job to do, is it recommended to remove the radiator and from there is it the usual set to TDC, remove bottom pulley, loosen tensioner, remove belt and replace? Are there any known problems or tips related to this job.
Engine is 1296, Petrol, Automatic transmission. Engine number is JDAJ100G000528835 if this helps

Many thanks
