New member. looking for information on 1.5 SOHC Motor

I have two Aveos both acquired New.
The older one was purchased new in 2007 and is SOHC 1.5 model.
Vehicle was going well until it went in for its 140km service by authorized agent.
Dealer did not accept responsibility for their shoddy workmanship that resulted in a rather expensive repair.

i am looking for information on cylinder head and timing belt removal and installation for this vehicle as I have now decided to do the repair myself.

Note: The DOHC 1.6 model only became available in South Africa after 2009.
