COOLANT REPLACEMENT

PROCEDURE

DRAIN ENGINE COOLANT

CAUTION:

To avoid being burned, do not remove the reservoir cap while the engine assembly and radiator assembly are still hot.

Thermal expansion may cause hot engine coolant and steam to blow out from the radiator reservoir assembly.

*a Vinyl Tube

Install a vinyl tube to the radiator drain cock plug on the radiator side.

*1	Reservoir Cap
*2	Radiator Drain Cock Plug
*3	Engine Side Bleeder Plug
*4	Heater Hose Side Bleeder Plug

Loosen the radiator drain cock plug and drain the engine coolant.

Tech Tips

Collect the engine coolant in a container and dispose of it according to the regulations in your area.

Remove the reservoir cap.
Tighten the radiator drain cock plug by hand.
Remove the vinyl tube from the radiator drain cock plug.

ADD ENGINE COOLANT
1. Remove the No. 1 engine cover sub-assembly.
2. *1 Engine Side Bleeder Plug
  
  *2 Heater Hose Side Bleeder Plug
  
  Install the vinyl tube to the engine side bleeder plug.
3. Place a piece of cloth, paper, etc., below the heater hose side bleeder plug.
4. Loosen the engine side bleeder plug and heater hose side bleeder plug.
  
  Tech Tips
  
  Place the end of the vinyl tube into a container before performing this procedure, as engine coolant will spill out of the vinyl tube.
5. B Line
  
  Add engine coolant to the radiator reservoir assembly filler opening until it is filled to the B line at the base of the radiator reservoir filler neck.
  
  Standard capacity
  
  7.9 liters (8.3 US qts, 7.0 Imp. qts)
  
  Note
  
  Never use water as a substitute for engine coolant.
  Tech Tips
  
  The B line is the lower edge of the inner wall of the filler neck.
  
  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).
6. Tighten the engine side bleeder plug and heater hose side bleeder plug by hand, in that order, once engine coolant is discharged from the hose installed to the bleeder plug.
7. Remove the vinyl tube from the engine side bleeder plug and tighten the engine side bleeder plug.
  
  Torque:
  
  12.7 N*m { 130 kgf*cm, 9 ft.*lbf }
8. Tighten the heater hose side bleeder plug.
9. Install the reservoir cap. [*1]
10. Start the engine and warm it up until the engine coolant level of the radiator reservoir assembly has stabilized. [*2]
  CAUTION:
  - Wear protective gloves.
  - Be careful as the radiator hoses are hot.
  - Keep your hands away from the cooling fan.
  Note
  - Perform the engine speed with 2000 rpm or less.
  - Make sure that the radiator reservoir assembly still has some engine coolant in it.
  - After starting the engine, if the radiator reservoir assembly does not have any engine coolant, perform the following: 1) stop the engine, 2) wait until the engine coolant has cooled down, and 3) add engine coolant until the engine coolant is filled to the B line.
  - If there is not enough engine coolant, the engine may burn out or overheat.
  - Pay attention to the needle of the engine coolant temperature meter. Make sure that the needle does not show an abnormally high temperature.
11. Stop the engine and wait until the engine coolant cools down to ambient temperature. [*3]
12. Check that the engine coolant level is between the FULL and LOW line. [*4]
  
  If the engine coolant level is below the LOW line, pour engine coolant of the specified concentration into the radiator reservoir assembly until it reaches the FULL line, and repeat the procedure from steps [*1] to [*4].
  
  If the engine coolant level is above the FULL line, drain engine coolant so that the engine coolant level is between the FULL and LOW line.
13. Install the No. 1 engine cover sub-assembly.
