The 4.0 V6 1GR- is a gasoline (petrol) engine designed by Toyota for applications in their SUVs and 4WD pickups.

Let’s take a closer look at the engine specifications. Other than that – they are real gems and with regular maintenance, you should see mileage racking up over 300k miles.

That will give you a very good idea of the kind of life it has endured. Also make sure you inspect the lowest parts of the vehicle, such as the rear diff and bash-plates underneath the engine. Check for dings and marks that will indicate serious off-road activity. If you are in the market for a used 4.0, make sure you inspect the undercarriage carefully, since these rugged, go-anywhere vehicles are well known to be used for off-road trails and dune driving. The V6 has quickly built up a reputation for being a go-anywhere, rugged, reliable little lump with a heart of gold.Ī common talking point with the 4.0 V6 is the failing water pump: (pick up a new one here on Amazon).Īnother common occurrence on the earlier single VVT-i V6 is a blown head gasket: (buy a replacement kit here on Amazon).Īlso, the automatic box “thud”: (get some high-quality ATF oil on Amazon). Many claims never to swap it for anything else out there, not even a diesel for better fuel consumption. Log onto any Toyota forum and you’ll find many threads of happy 4.0 V6 owners who swear by these engines. What the owners have to say about mileage and maintenance.
