The Nissan VQ40DE is a 4.0 litre DOHC V6 with 24 valves, naturally aspirated and port injected rather than direct. It was built from 2004 and fitted to the Navara D40, Pathfinder R51 and Xterra. The VQ40DE uses timing chains, not a belt. Four of the 5 parts on the VQ40DE page are rebuild sets and the fifth is a chain tensioner.
Parts for the same 4.0 litre V6 are also filed under the short code on the VQ40 page, which holds 17 items.
Pistons and ring sets
A piston and ring set is listed for the VQ40DE in 0.5mm oversize. An NPR ring set covers both the VQ40DE and the 3.5 litre VQ35DE. Oversize pistons mean the block has been bored already, so check the size stamped on the crowns.
Main bearings and thrust washers
Main bearing sets and thrust washer sets are both listed under the VQ40DE. Thrust washers are easy to leave off a bearing order, and they are what set crankshaft end float.
Timing chain parts for the VQ40DE
The genuine left hand side chain tensioner assembly is shared with the VQ35DE and with the YD25DDTI and V9X diesels. Tensioners are bank specific, so check which side you are replacing before you order.
