Disadvantages of the GM LLV engine

  • This is a reliable and resourceful power unit without any significant weaknesses.
  • The main thing is to regularly check the condition of the water pump and fan viscous coupling.
  • These units are short-lived, and aluminum block engines do not tolerate overheating.
  • After 200,000 km of run, valve seat wear and timing chain stretching occur.
  • Cracked exhaust manifolds replaced under warranty on 2009 and 2010 pickups.
