Toyota 5VZ-FE

Toyota 5VZ-FEThe Toyota 5VZ-FE is a 3.4 L (3,378 cc, 206.14 cu·in) V6, four-stroke cycle water-cooled naturally aspirated internal combustion gasoline engine, manufactured by the Toyota Motor Corporation since 1995 to 2004. The engine was producted on Toyota Motor Manufacturing Alabama.

The 5VZ-FE engine has 6 cylinders in a V arrangement at a bank angle of 60° The 5VZ-FE features a cast-iron cylinder block with a four-bearings crankshaft and two aluminum heads with two camshafts (DOHC) and four valves per cylinder (24 in total). The Toyota 5VZ-FE engine is equipped with SFI (Sequential Multiport Fuel Injection) system and “Direct Ignition System” (DIS) ignition system with three coils (one coil for two cylinders). The engine is also equipped with “Electronic Spark Advance” (ESA) which used the ECM to determine the ignition timing based on signals from sensors and adjust timing in response to engine knocking.

The cylinder bore is 93.5 mm (3.68 in) and the piston stroke is 82.0 mm (3.23 in). Compression ratio rating is 9.6:1. The Toyota 5VZ-FE engine produced 193 PS (142 kW; 190 HP) at 4,800 rpm of maximum power and 298 N·m (30.4 kg·m, 219.6 ft·lb) at 3,600 rpm of maximum torque.

The breakdown of the engine code is as follows:

  • 5 – 5 generation engine
  • VZ – Engine family
  • F – Economy narrow-angle DOHC
  • E – Multi Point Fuel Injection

Cylinder block

The 5VZ-FE engine has deep-skirt cast-iron cylinder block in a V arrangement at a bank angle of 60°. This engine’s firing order is 1–2–3–4–5–6. The crankshaft is supported by 4 bearings.

The 5VZ-FE engine has a cast-iron crankshaft. The crankshaft is integrated with 5 counterbalance weights, for the LandCruiser Prado (90-Series) the crankshaft has nine counterbalance weights and a dual-mode damper. Crankshaft main journal diameter is 64.000 mm (2.52 in) and crankpin diameter is 55.000 mm (2.16 in)

The engine used forged, sintered connecting rods and aluminum pistons with full-floating type piston pins. Each piston is equipped with two compressions and one oil control rings. The cylinder bore is 93.5 mm (3.68 in) and the piston stroke is 82.0 mm (3.23 in). Compression ratio rating is 9.6:1.

Cylinder head

The cylinder head is made of aluminum alloy. The 5MZ-FE engine has double overhead camshafts DOHC design with four valves per cylinder (two intake and two exhaust valves). The intake camshafts are driven by a belt and the exhaust camshafts are driven by gears off the intake camshafts. The intake duration is 226° and the exhaust duration is 226°. The stock size of fuel injectors is 276 cm2 per minute.

Valve clearance adjustment data

Calculate the thickness of new adjusting valve shim so valve clearance comes within specified values.

R = Thickness of removed valve shim
N = Thickness of new valve shim
M = Measured valve clearance

Intake:
N = R + [M – 0.20 mm (0.008 in)]
Exhaust:
N = R + [M – 0.30 mm (0.012 in)]

Valve shims are available in 17 sizes to range from 2.50 mm (0.0984 in) to 3.30 mm (0.1299 in), in steps of 0.05 mm (0.0020 in).

Example (exhaust valve):
R = 2.70 mm
M = 0.52 mm
N = 2.70 + (0.45 – 0.30) = 2.85 mm.
