Timing Belt (W/O Dpf) Installation

Using a 10 mm hexagon wrench, install a new washer and the No. 1 timing belt idler with the bolt.

Torque:

35 N*m{357 kgf*cm, 26 ft.*lbf}

Check that the idler pulley moves smoothly.
If the idler pulley does not move smoothly, check the installation condition of the idler and washer.

Check that the timing marks are aligned as shown in the illustration.

NOTICE:

1. Make sure that the engine is cold.
   
2. When turning the crankshaft, the valve heads will hit against the piston. Do not turn the crankshaft more than necessary.
   

HINT:

If reusing the timing belt, align the points marked during removal, and install the belt with the arrow pointing in the direction of crankshaft revolution.

Install the timing belt to the pump drive shaft pulley, camshaft timing pulley and No. 1 timing belt idler in sequence.

Place the tensioner upright. Then set a press on the top of the tensioner.

NOTICE:

1. Do not scratch or deform the rod end.
   
2. Press in the tensioner rod.
   
3. Protect the tip of the push rod with a cloth in order to prevent damage.
   

Using the press, slowly push in the push rod using 981 to 9800 N (100 to 999 kgf, 220 to 2203 lbf) of force.

NOTICE:

Do not apply a load of over 9800 N (999 kgf, 2203 lbf) to the push rod.

Align the holes of the push rod and housing. Then pass a 1.5 mm hexagon wrench through the holes to fix the push rod in place.

Temporarily install the timing belt tensioner with the 2 bolts while pushing the idler pulley toward the timing belt.

Tighten the 2 bolts.

Torque:

13 N*m{133 kgf*cm, 10 ft.*lbf}

NOTICE:

Uniformly tighten the 2 bolts.

Remove the 1.5 mm hexagon wrench from the tensioner.

Turn the crankshaft clockwise 720° and check that the timing marks are aligned as shown in the illustration.

Install the timing belt cover and 6 washers with the 6 bolts.

Torque:

6.0 N*m{61 kgf*cm, 53 in.*lbf}

Install the fan pulley to the engine water pump.

Install the fan shroud together with the fluid coupling with fan between the radiator and engine component.

NOTICE:

Be careful not to damage the radiator core.

Install the fluid coupling with fan to the fan pulley with the 4 nuts.
Tighten the nuts as much as possible by hand.

Attach the claws of the fan shroud to the radiator.

Install the fan shroud with the 2 bolts.

Torque:

5.0 N*m{51 kgf*cm, 44 in.*lbf}

Install the fan and generator V belt (HILUX_TGN26 RM000001474016X_01_0001.html).

Tighten the 4 nuts of the fluid coupling with fan.

Torque:

23 N*m{235 kgf*cm, 17 ft.*lbf}

Install the radiator reservoir with the 2 bolts.

Torque:

5.0 N*m{51 kgf*cm, 44 in.*lbf}

Connect the No. 1 and No. 2 water by-pass hoses to the radiator.

Install the oil reservoir with the 3 bolts.

Torque:

4.5 N*m{46 kgf*cm, 40 in.*lbf}

Tighten the radiator drain cock plug by hand.

Tighten the cylinder block drain cock plug.

Torque:

8.0 N*m{82 kgf*cm, 71 in.*lbf}

Fill the radiator with TOYOTA Super Long Life Coolant (SLLC) to the B line of the radiator reservoir.

Standard capacity:

9.8 liters (10.4 US qts, 8.6 Imp. qts)

NOTICE:

Never use water as a substitute for engine coolant.

HINT:

1. TOYOTA vehicles are filled with TOYOTA SLLC at the factory. In order to avoid damage to the engine cooling system and other technical problems, only use TOYOTA SLLC or similar high quality ethylene glycol based non-silicate, non-amine, non-nitrite, non-borate coolant with long-life hybrid organic acid technology (coolant with long-life hybrid organic acid technology consists of a combination of low phosphates and organic acids).
   
2. Please contact your TOYOTA dealer for further details.
   

Press the inlet and outlet radiator hoses several times by hand, and then check the level of the coolant.
If the coolant level drops below the B line, add TOYOTA SLLC to the B line.

Install the radiator reservoir cap.

Using a wrench, install the vent plug.

Torque:

2.0 N*m{20 kgf*cm, 17 in.*lbf}

Bleed air from the cooling system.

1. Warm up the engine until the thermostat opens. While the thermostat is open, circulate the coolant for several minutes.
   

2. Maintain the engine speed at 2500 to 3000 rpm.
   

3. Press the inlet and outlet radiator hoses several times by hand to bleed air.
   

   CAUTION:

   When pressing the radiator hoses:

   1. Wear protective gloves.
      
   2. Be careful as the radiator hoses are hot.
      
   3. Keep your hands away from the radiator fan.
      

4. Stop the engine and wait until the coolant cools down to ambient temperature.
   

   CAUTION:

   Do not remove the radiator reservoir cap while the engine and radiator are still hot. Pressurized, hot engine coolant and steam may be released and cause serious burns.

After the coolant cools down, check that the coolant level is at the F line.
If the coolant level is below the F line, add TOYOTA SLLC to the F line.

Fill the radiator with coolant and attach a radiator cap tester.

Warm up the engine.

Using the radiator cap tester, increase the pressure inside the radiator to 118 kPa (1.2 kgf/cm², 17 psi), and check that the pressure does not drop.
If the pressure drops, check the hoses, radiator and water pump for leaks. If no external leaks are found, check the heater core, cylinder block and head.
