INSPECT AIR CLEANER FILTER ELEMENT SUB-ASSEMBLY
-
Remove the air cleaner filter element from the air cleaner case sub-assembly.
-
Visually check that there is no dirt, clog, and damage to the air cleaner filter element.
Tip:
-
If there is any dirt or clog on the air cleaner filter element, clean it with compressed air.
-
If any dirt or clog remains even after cleaning the air cleaner element with compressed air, replace it.

When reinstalling a belt used for over 5 minutes, perform the check based on the used deflection value.
-
V belt tension and deflection value should be checked after two revolution of engine cranking.
-
When using a belt tension gauge, confirm the accuracy first by using a master gauge.

INSPECT ENGINE IDLE SPEED
-
Warm up the engine.
-
When using an intelligent tester:
-
Connect the intelligent tester to the DLC3.
Idle speed 720 to 820 rpm (A/C OFF) 750 to 850 rpm (A/C ON) Tip:Refer to the intelligent tester operator's manual for further details.
-
-
When not using an intelligent tester:
-
Using SST, connect the tachometer test probe to terminal 9 (TAC) of the DLC3.
09843-18040 -
Check the idle speed.
Idle speed 720 to 820 rpm (A/C OFF) 750 to 850 rpm (A/C ON) Note:Switch off all accessories.

INSPECT COMPRESSION
Tip:If there is a lack of power, excessive oil consumption or poor fuel economy is suspected. Measure the compression pressure.
-
Warm up and stop the engine.
-
Remove the glow plugs. (Click here)
-
Disconnect the spill control valve connector.
-
Check the cylinder compression pressure.
Tip:Turn the starter before measuring the compression pressure and remove the foreign objects.
-
Install SST (attachment) to the glow plug hole.
09992-00025 09992-00121 13 N*m 133 kgf*cm 10 ft.*lbf -
Connect SST (compression gauge) to the SST (attachment).
09992-00025 09992-00211 -
Fully open the throttle valve, and start the engine.
-
While cranking the engine, measure the compression pressure.
Tip:Always use a fully charged battery to obtain engine revolution of 250 rpm or more.
-
Repeat steps (a) through (d) for each cylinder.
Note:This measurement must be done as quickly as possible.
Compression pressure 3,138 kPa (32.0 kgf/cm2, 455 psi) or more Minimum pressure 1,961 kPa (20.0 kgf/cm2, 284 psi) Difference between each cylinder 490 kPa (5.0 kgf/cm2, 71 psi) or less -
If the cylinder compression in one or more cylinders is low, pour a small amount of engine oil into the cylinder through the glow plug hole and repeat steps (a) through (d) for the cylinder with low compression.
-
If adding oil helps the compression, the piston rings and/or cylinder bore may be worn or damaged.
-
If pressure stays low, a valve may be stuck or the seating may be improper, or there may be leakage past the gasket.
-
-
Remove the SST.
-
Reinstall the glow plugs. (Click here)
-
Reconnect the spill control valve connector.
