The Nissan VQ series of V6 engines, which originally dates back to 1994 to replace the VG series of V6 engines, has been a stronghold in Nissan and Infiniti's offerings over the past two decades. Its most popular version is the VQ35DE, which were fitted many vehicles in the early 2000's including the Nissan Altima, Maxima, Murano, Pathfinder and Quest; and the Infiniti G35, M35 and FX35, and is still used in production vehicles today.


In this video we take an indepth look at a VQ35DE sample from a 2006 Nissan Murano, tear it down to see what's inside and how it works. We will also look at what makes this engine such a strong contender for Nissan, being fairly reliable and versatile across its product lineup. Additionally, we look at why these engines do fail, and examine common failure modes discovered over the years.


Nissan has definitely created an award winning engine that was way ahead of its time almost 20 years ago when it debuted. Sadly, V6 engines in its lineup are slowly being replaced by turbo 4 cylinders, but the VQ series will still be sought after for years to come.
