The Dispatch | Expert | Scudo Hub

I can't find the workshop manuals for the 66 plate Citroen jumpy/ dispatch or even their identical counterparts such as the Peugeot expert. I've got the 2.0 engine and I need to change the timing belt. I know the engine code is AHK. Can someone point me in the right direction as to what kind of engine this is? I can tell that it's a DW10? I'm not sure

Please help

Cheeeers!
