Overall Function CheckNJEC0489Use this procedure to check the overall function of the cooling fan.
During this check, a DTC might not be confirmed.
WARNING:
Never remove the radiator cap when the engine is hot. Serious
burns could be caused by high pressure fluid escaping from
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 and mixture ratio (using coolant tester)
in the reservoir tank and radiator.
Allow engine to cool before checking coolant level and
mixture ratio.
+If the coolant level in the reservoir tank and/or radiator is below
the proper range, skip the following steps and go to ªDiagnos-
tic Procedureº, EC-410.
+If the coolant mixture ratio is out of the range of 45 to 55%,
replace the coolant in the following procedure LC-18, ªChang-
ing Engine Coolantº.
2) Confirm whether customer filled the coolant or not. If customer
filled the coolant, skip the following steps and go to ªDiagnos-
tic Procedureº, EC-410.
3) Turn ignition switch ªONº.
4) Perform ªCOOLING FANº in ªACTIVE TESTº mode with CON-
SULT-II.
5) If the results are NG, go to ªDiagnostic Procedureº, EC-410.

Be careful not to overheat engine.
4) Set temperature control lever to full cold position.
5) Turn air conditioner switch ªONº.
6) Turn blower fan switch ªONº.
7) Run engine at idle for a few minutes with air conditioner oper-
ating.

CAUTION:
+After removing timing chain, do not turn crankshaft and
camshaft separately, or valves will strike piston heads.
+When installing chain tensioner, oil seats, or other sliding
parts, lubricate contacting surfaces with new engine oil.
+Apply new engine oil to bolt threads and seat surfaces
when installing camshaft sprocket and crankshaft pulley.
+When removing oil pump assembly, remove camshaft
position sensor (PHASE), then remove timing chain from
engine.
+Be careful not to damage sensor edges.

WARNING:
+Position vehicle on a flat and solid surface.
+Place chocks at front and back of rear wheels.
+Do not remove engine until exhaust system has com-
pletely cooled off, otherwise, you may burn yourself
and/or fire may break out in fuel line.
+Before disconnecting fuel hose, release pressure.
Refer to EC-40, ªFuel Pressure Releaseº.
+Be sure to lift engine and transaxle in a safe manner.
+For engines not equipped with engine slingers, attach
proper slingers and bolts described in PARTS CATALOG.
CAUTION:
+When lifting engine, be sure to clear surrounding parts.
Use special care near accelerator wire casing, brake lines
and brake master cylinder.
+When lifting the engine, always use engine slingers in a
safe manner.
+When removing drive shaft, be careful not to damage
grease seal of transaxle.
+Before separating engine and transaxle, remove crank-
shaft position sensor (POS) from the cylinder block
assembly.
+Always be extra careful not to damage edge of crankshaft
position sensor (POS), or signal plate teeth.
Engine cannot be removed separately from transaxle. Remove
engine with transaxle as an assembly.

lower radiator hose, and remove radiator filler cap to drain
coolant.
3. Remove reservoir tank, drain coolant, then clean reservoir
tank.
+Be careful not to allow coolant to contact drive belts.
4. Cover the exhaust tube heat shield to prevent from splashing
coolant.

5. Remove drain plug on cylinder block and air relief plug.
6. Check drained coolant for contaminants such as rust, corro-
sion or discoloration. If contaminated flush engine cooling
system, refer to LC-20, ªFLUSHING COOLING SYSTEMº.
7. Blow the coolant around the exhaust tube heat shield.
Ð REFILLING ENGINE COOLANT ÐNJLC0037S021. Install reservoir tank, radiator drain cock or lower radiator hose
and cylinder block drain plug.
+Apply sealant to the thread of cylinder block drain plug.
: 35 - 44 N´m (3.50 - 4.50 kg-m, 26 - 32 ft-lb)
2. Fill radiator slowly with coolant until coolant spills from the air
relief plug, then install air relief plug.
Air relief plug:

3. Fill radiator and reservoir tank to specified level.
4. Warm up engine to normal operating temperature without
radiator cap installed.
+If coolant overflows radiator filler hole, install filler cap.
5. Run engine at 2,500 rpm for 10 seconds and return to idle
speed with radiator cap installed.
+Repeat two or three times.
Watch coolant temperature gauge so as not to overheat the
engine.
6. Stop engine and cool it down.
+Cool down using a fan to reduce the time.
+If necessary, refill radiator up to filler neck with coolant.
7. Refill reservoir tank to MAX level line with coolant.
8. Repeat steps 4 through 7 two or more times with radiator cap
installed until coolant level no longer drops.
9. Check cooling system for leaks with engine running.
10. Warm up engine, and check for sound of coolant flow while
running engine from idle up to 3,000 rpm with heater tempera-
ture controller set at several positions between COOL and
HOT.
+Sound may be noticeable at heater water cock.
