Disadvantages of the GM LLV engine
This power unit has no major flaws and is dependable and resourceful.
The most important thing is to routinely inspect the water pump and fan viscous coupling.
Aluminum block engines cannot withstand overheating, and these units have a limited lifespan.
Timing chain stretching and valve seat wear happen after 200,000 kilometers of operation.
Under warranty, 2009 and 2010 pickups had their cracked exhaust manifolds replaced.
