SLLC is pre-mixed (the U.S.A. models: 50 % coolant and 50 % deionized water, the Canada. models:
55 % coolant and 45 % deionized water). Therefore, no dilution is needed when SLLC in the vehicle is
added or replaced.
If LLC is mixed with SLLC, the interval for LLC (every 25,000 miles / 40,000 km or 24 months
whichever comes first) should be used.
You can also apply the new maintenance interval (every 50,000 miles / 80,000 km) to vehicles initially
filled with LLC (red-colored), if you use SLLC (pink-colored) for the engine coolant change.

2. Air Cleaner
A nonwoven, full-fabric type air cleaner element is used.
A charcoal filter, which adsorbs the HC that accumulates in the intake system when the engine is stopped,
is used in the air cleaner cap in order to reduce evaporative emissions.
3. Throttle Body
The linkless-type throttle body is used and it realizes excellent throttle control.
A DC motor with excellent response and minimal power consumption is used for the throttle control motor.
The ECM performs the duty ratio control of the direction and the amperage of the current that flows to
the throttle control motor in order to regulate the opening angle of the throttle valve.

ENGINE - 2AZ-FE ENGINE
Service Tip
The canister pump module performs the EVAP leak check. This check is done approximately five
hours after the engine is turned off. So you may hear sound coming from underneath the luggage
compartment for several minutes. It does not indicate a malfunction.
The pinpoint pressure test procedure is carried out by pressurizing the fresh air line that runs from
the pump module to the air filler neck. For details, refer to the 2006 RAV4 Repair Manual (Pub.
No. RM01M1U).

10. EVAP (evaporative Emission) Control System
General
The EVAP (evaporative emission) control system prevents the vapor gas that is created in the fuel tank from
being released directly into the atmosphere.
The canister stores the vapor gas that has been created in the fuel tank.
The ECM controls the purge VSV in accordance with the driving conditions in order to direct the vapor
gas into the engine, where it is burned.
In this system, the ECM checks the evaporative emission leak and outputs DTC (Diagnostic Trouble
Code) in the event of a malfunction. An EVAP (evaporative emission) leak check consists of an
application of a vacuum pressure to the system and monitoring the changes in the system pressure in order
to detect a leakage.
This system consists of the purge VSV, canister, refueling valve, canister pump module, and ECM.
The ORVR (Onboard Refueling Vapor Recovery) function is provided in the refueling valve.
The canister pressure sensor has been included to the canister pump module.
The canister filter has been provided on the fresh air line. This canister filter is maintenance-free.
The followings are the typical conditions for enabling an EVAP leak check:
Typical Enabling
Condition
Five hours have elapsed after the engine has been turned OFF*.
Altitude: Below 2400 m (8000 feet)
Battery voltage: 10.5 V or more
Ignition switch: OFF
Engine coolant temperature: 4.4 to 35C (40 to 95F)
Intake air temperature: 4.4 to 35C (40 to 95F)
*: If engine coolant temperature does not drop below 35C (95F), this time should be extended to 7hours.
Even after that, if the temperature is not less than 35
C (95F), the time should be extended to 9.5 hours.

Service Tip
The engine oil in the oil filter can be drained by removing the drain plug and inserting the drain
pipe supplied with the element into the oil filter. For details, refer to the 2006 RAV4 Repair Manual
(Pub. No. RM01M1U).
The engine oil maintenance interval for a model that has an oil filter with a replaceable element
is the same as that for the conventional model.
EG-87
4. Oil Filter
An oil filter with a replaceable element is used. The element uses a high-performance filter paper to
improve filtration performance. It is also combustible for environmental protection.
An aluminum alloy filter cap is used to extend its life.
This oil filter has a structure which can drain the engine oil remaining in the oil filter. This prevents engine
oil from spattering when replacing the element and allows the technician to work without touching hot
engine oil.

SLLC is pre-mixed (the U.S.A. models: 50 % coolant and 50 % deionized water, the Canada. models: 55
% coolant and 45 % deionized water), so no dilution is needed when SLLC in the vehicle is added or

If LLC is mixed with SLLC, the interval for LLC (every 25,000 miles (USA), 32,000 km (CANADA) or
24 months whichever comes first) should be used.
2. Water Pump
The water pump has two volute chambers, and circulates coolant uniformly to the left and right banks of the
cylinder block.

Along with the use of the air intake control
system, an air intake control valve is provided
on the air cleaner case. For details, see page
EG-128.
Resonators have been provided to reduce the
amount of intake air sound.
3. Throttle Body
A linkless-type throttle body in which the throttle position sensor and the throttle control motor are integrated
is used. It realizes excellent throttle valve control. For details, see page EG-118.
In the throttle control motor, a DC motor with excellent response and minimal power consumption is used.
The ECM performs the duty ratio control of the direction and the amperage of the current that flows to
the throttle control motor in order to regulate the throttle valve angle.

3. Spark Plug
Long-reach type spark plugs are used. This type of spark plugs allow the area of the cylinder head to
receive the spark plugs to be made thick. Thus, the water jacket can be extended near the combustion
chamber, which contributes to cooling performance.
Iridium-tipped spark plugs are used to achieve a 120,000 miles (193,000 km) maintenance interval. By
making the center electrode of iridium, the superior ignition performance as platinum-tipped spark plugs
is achieved and durability has been increased.

GENERAL MAINTENANCE
(2006/01- )
1. GENERAL NOTES
• Maintenance requirements vary depending on the
country.
• Check the maintenance schedule in the owner's
manual supplement.
• Following the maintenance schedule is mandatory.
• Determine the appropriate time to service the vehicle
using either miles driven or time elapsed, whichever
reaches the specification first.
• Maintain similar intervals between periodic
maintenance, unless otherwise noted.
• Failing to check each vehicle part could lead to poor
engine performance and increase exhaust emissions.
