Disadvantages of the Renault 2TR engine

  • This unit appeared in 2007 and the QR25DE problems of the first years did not affect it.
  • The main thing is to prevent overheating, since here it immediately breaks through the gasket and leads the cylinder head.
  • After 100,000 km of run, many are faced with an oil burner due to the occurrence of rings.
  • The timing chain also does not differ in resource and often requires replacement by 150 thousand km.
  • All remaining problems are related to sensor failures and electric throttle glitches.
