I researched this when considering the diesel in 2013/2014. I've read the Alldata procedure, and it doesn't look that bad. How tight is it in the engine bay is another question.
Google the EN tool numbers found in Alldata. You'll find global suppliers of the tools. There's a plug that's removed in the block, and a steel pin that's installed when the crank is at TDC.
I had a link to a GM training video showing this belt change, but the channel has been removed. There's a company in Italy if I remember correctly that makes equivalent tools which can be obtained from Amazon.uk or other European Amazon sites.
