PERIODIC MAINTENANCEPFP:00026
Periodic MaintenanceELS000AM
The following tables show the normal maintenance schedule. Depending upon weather and atmospheric con-
ditions, varying road surfaces, individual driving habits and vehicle usage, additional or more frequent mainte-
nance may be required.
Periodic maintenance beyond the last period shown on the tables requires similar maintenance.
ENGINE AND EMISSION CONTROL MAINTENANCE (QR20DE AND QR25DE PETROL ENGINE)
(Annual Mileage <30,000 Km/year)
Abbreviations: I = Inspect and correct or replace as necessary, R = Replace,.
NOTE:

Maintenance items with “ ” should be performed more frequently according to “Maintenance Under Severe Driving
Conditions”.

(1)Periodic maintenance is not required. However, if valve noise increases, check valve clearance.

(2) Replace the drive belt if found damaged or if the auto belt tensioner reading reaches the maximum limit.

(3) First replace at 90,000 Km (54,000 miles)/60 months, then every 60,000 km (36,000 miles)/48 months. Perform "I"
(Checking the mixture ratio and correcting the mixture ratio if necessary) at the middle of replacement interval.

(4) Fuel filter is maintenance-free. For service procedures, refer to FL section. MAINTENANCE OPERATIONMAINTENANCE INTERVAL

CHECKING RADIATOR SYSTEM FOR LEAKS

To check for leakage, apply pressure to the cooling system with
a radiator cap tester (commercial service tool) and a radiator
cap tester adapter (special service tool).
WARNING:
Do not remove radiator cap when engine is hot. Serious burns
could occur from high-pressure engine coolant escaping from
radiator.
CAUTION:
Higher test pressure than specified may cause radiator damage.
NOTE:
In a case that engine coolant decreases, replenish radiator with engine coolant.

If anything is found, repair or replace damaged parts.
Checking Fuel LinesELS000ZG
Inspect fuel lines, filler cap and tank for improper attachment, leaks,
cracks, damage, loose connections, chafing or deterioration. If nec-
essary, repair or replace damaged parts.
Changing Air Cleaner FilterELS000ZH
VISCOUS PAPER TYPE
The viscous paper type filter does not need cleaning.
Changing Engine OilELS000ZI
WARNING:

Be careful not to burn yourself, as engine oil may be hot.

Prolonged and repeated contact with used engine oil may cause skin cancer; try to avoid direct
skin contact with used engine oil. If skin contact is made, wash thoroughly with soap or hand
cleaner as soon as possible.
1. Warm up engine, put vehicle horizontally and check for oil leakage from engine components. Refer to LU-
7, "ENGINE OIL LEAKAGE" .
2. Stop engine and wait for 10 minutes.Testing pressure:
157 kPa (1.57 bar, 1.6 kg/cm

Checking and Changing Spark PlugsELS000ZK
REMOVAL
1. Remove ignition coil. Refer to EM-29, "IGNITION COIL" .
2. Remove spark plug with spark plug wrench (commercial service
tool).
CAUTION:
Do not drop or shock it.
INSPECTION AFTER REMOVAL
Use standard type spark plug for normal condition.
Hot type spark plug is suitable when fouling occurs with standard type spark plug under conditions such as:

Frequent engine starts

Low ambient temperatures
Cold type spark plug is suitable when spark plug knock occurs with standard type spark plug under conditions
such as:

Extended highway driving

Frequent high engine revolution

Check plug gap of each spark plug.

If out of standard, adjust or replace spark plug.

Use a wire brush for cleaning, if necessary.
INSTALLATION
Install in the reverse order of removal.
Checking EVAP Vapor LinesELS000ZL
1. Visually inspect EVAP vapor lines for improper attachment and for cracks, damage, loose connections,
chafing and deterioration.
2. Inspect fuel tank filler cap vacuum relief valve for clogging, sticking, etc.
Refer to EC-474, "
EVAPORATIVE EMISSION LINE DRAWING" .

REMOVAL
1. Remove air duct, air cleaner case and mass air flow sensor assembly. Refer to EM-133, "AIR CLEANER
AND AIR DUCT" .
2. Remove fuel filter protector.
3. Remove fuel hoses from fuel filter bracket.
CAUTION:
Plug the pipe to prevent fuel from draining.
4. Remove fuel filter with fuel filter bracket.
CAUTION:
Do not splash fuel during removal. If fuel is splashed,
immediately wipe it off.
5. Using band-type fuel filter wrench (commercial service tool),
remove fuel filter.
6. Turn fuel filter upside down to drain fuel.
7. Remove drain plug from fuel filter.
INSTALLATION
Install in reverse order of removal, paying attention to following:

Replace O-ring on drain plug with new one.

Screw the fuel filter by hand until packing contacts sealing surface of bracket. Then tighten it by turning
approximately 2/3 turn.

After installation, bleed air from fuel path. Refer to FL-18, "Air Bleeding" .
INSPECTION AFTER INSTALLATION
Make sure there is no fuel leakage at connections in the following steps.

Start the engine and rev it up and check for fuel leaks at connections.

VISCOUS PAPER TYPE
The viscous paper type air cleaner filter does not require any clean-
ing operation between renewal.
