Later, Toyota put this motor in some of their other SUVs designed for rough terrain.


There are a number of key differences between this engine and its predecessor, the 2VZ engine—the larger displacement is just one of them.

The cylinder block, made of cast iron, is the same size but 20 mm taller (the height is 223 mm).

The V-shaped block has a 60-degree angle between its cylinders. A new forged crankshaft with nine counterweights and an 82 mm stroke is housed within the block.

Toyota 3VZ-FE 3.0L Engine Problems & Reliability

The first issue is that the engine is overheating. Often, a faulty head gasket is a culprit. The coolant fan isn’t functioning properly, either.


Keeping the radiator clean and the coolant level at the right level for this engine will help prevent future overheating issues.

Cracks in the cylinder heads and rapid wear on the connecting rod bearings are problems plaguing the 3VZ.

One hundred and eighty thousand kilometres is about the limit for the engine’s lifespan (300,000 km).

Any signs of impending death, such as a rise in oil consumption or knocking sounds coming from the cylinder block, should be taken seriously.

Toyota 3VZ-FE 3.0L Engine Review 

The 3VZ-FE Toyota 3.0L V6 engine was manufactured from 1992 until 1997. It was a very popular option for Toyota trucks and SUVs including T100, Tacoma, and the 4Runner, Tacoma, and T100. For a full review, please check this YouTube video Here.

Toyota 3VZ-FE 3.0L Engine FAQ 

Is the 3VZ EA a good engine?

Its engine is inadequate for powering larger vehicles such as the Toyota 4Runner and T100.A block made of cast iron, for example, is quite sturdy.

The 3.0 V6 head gaskets have major problems when used with an aluminium cylinder head.

What cars have a 3VZ FE engine?

From 1992 to May 1997, depending on the market, the 3VZ-FE was used in the Camry platform.

In North America, the engine was only available in 1992 and 1993, whereas in Australia and New Zealand, it was available from 1992 to 1996.

Until May 1997, the engine could be purchased in certain Asian markets in the Toyota Windom.

Is the 3VZE an interference engine?

Both the 3VZE and the 5VZ-FE utilize a belt drive that prevents interference between the two engines.

Because of this, improper timing prevents the valves from closing on the pistons.
