GM 1.6 LXV (Variable Camshaft Phasing) Timing Belt Replacement

[Salto_Jorge]

2009+ Aveo's (Sonic, Cruze, Astra, Swift ) have the LVX/LUW engine


Gates TCKWP338 Timing Belt Component Kit with Water Pump
Does not include new bolts for the idler or tensioner.





Replaced my water pump, next was to be the timing belt.

The Aveo has been taken apart for days trying to figure out how to remove the timing belt.
Text based instructions are one thing, a video is another thing.
When I was at the point of giving up, I found these videos based on looking at the camshafts.

Found two (non-English) videos for a cruze but that does not matter, the engine is the same.

Did not mess with my transmission like they do in the first video.

Had to design/make a tool to hold the camshafts.
Marked my old T-Belt just like the instructions for the older model engine.

Never found out what the tensioner pulley pin was for or how it worked.
