On Board Diagnosis LogicUBS00QKV
If the cooling fan or another component in the cooling system malfunctions, engine coolant temperature will
rise. When the engine coolant temperature reaches an abnormally high temperature condition, a malfunction
is indicated.
This self-diagnosis has the one trip detection logic.
CAUTION:
When a malfunction is indicated, be sure to replace the coolant. Refer to CO-8, "
Changing Engine
Coolant" . Also, replace the engine oil. Refer to LU-6, "Changing Engine Oil" .
1. Fill radiator with coolant up to specified level with a filling speed of 2 liters per minute. Be sure to
use coolant with the proper mixture ratio. Refer to MA-12, "
Anti-freeze Coolant Mixture Ratio" .
2. After refilling coolant, run engine to ensure that no water-flow noise is emitted.
Overall Function CheckUBS00QKW
Use this procedure to check the overall function of the cooling fan. During this check, a DTC might not be con-
firmed.
WA RN ING:
Never remove the radiator cap when the engine is hot. Serious burns could be caused by high pres-
sure fluid escaping from the reservoir tank or the radiator.
Wrap a thick cloth around cap. Carefully remove the cap by turning it a quarter turn to allow built-up
pressure to escape. Then turn the cap all the way off.
WITH CONSULT-II
1. Check the coolant level in the reservoir tank and radiator.
Allow engine to cool before checking coolant level.
If the coolant level in the reservoir tank and/or radiator is below
the proper range, skip the following steps and go to EC-450,
"PROCEDURE FOR MODELS WITH A/C" or EC-454, "PRO-
CEDURE FOR MODELS WITHOUT A/C" .
2. Confirm whether customer filled the coolant or not. If customer
filled the coolant, skip the following steps and go to EC-450,
"PROCEDURE FOR MODELS WITH A/C" or EC-454, "PRO-
CEDURE FOR MODELS WITHOUT A/C" .
3. Turn ignition switch ON.

2. Install engine to engine stand as follows;
a. Remove flywheel (M/T models) or drive plate (1) (A/T or CVT
models).

Secure flywheel (M/T models) or drive plate (A/T or CVT mod-
els) using Tool (A), and remove bolts.
CAUTION:
Be careful not to damage or scratch drive plate (A/T or CVT
models) and contact surface for clutch disc of flywheel (M/T
models).
NOTE:
Figure shows drive plate (A/T or CVT models)
b. Lift the engine with a hoist to install it onto widely use engine stand.
CAUTION:

Use the engine stand that has a load capacity [approximately 135 kg (298 lb) or more] large
enough for supporting the engine weight.

If the load capacity of stand is not adequate, remove the following parts beforehand to reduce the
potential risk of overturning stand.
–Exhaust manifold; Refer to EM-21, "EXHAUST MANIFOLD" .
–Rocker cover; Refer to EM-30, "IGNITION COIL, SPARK PLUG AND ROCKER COVER" .
NOTE:
The figure shows an example of widely used engine stand (A)
that can support mating surface of transaxle with flywheel (M/T
models) or drive plate (A/T or CVT models) removed.
CAUTION:
Before removing the hanging chains, make sure the engine
stand is stable and there is no risk of overturning.
3. Remove oil pan (upper and lower). Refer to EM-24, "
OIL PAN" .
4. Remove cylinder head. Refer to EM-62, "
CYLINDER HEAD" .
5. Remove thermostat housing. Refer to CO-18, "
THERMOSTAT" .
