  1. Check the tension of the drive belt. (Refer to «ON-VEHICLE SERVICE»(ref-289376-S33084051282008063000000) ).
  2. Check the tension of the drive belt in the following procedures. Connect special tool microphone assembly (MB992082) to special tool belt tension meter (MB992081) of special tool belt tension meter set (MB992080). Press the "POWER" button to turn on the power supply. Press the numeral key of "1" and check that "No. 1" appears on the upper left of the display. NOTE: This operation is to temporarily set the preset data such as the belt specifications, because if the measurement is taken without input of the belt specifications, conversion to tension value (N) cannot be made, resulting in judgement of error. Press "Hz" button twice to change the display to the frequency display (Hz). CAUTION: The temperature of the surface of the belt should be as close to normal temperature as possible. Do not allow any contaminants such as water or oil to get onto the microphone. If strong gusts of wind blow against the microphone or if there are any loud sources of noise nearby, the values measured by the microphone may not correspond to actual values. If the microphone is touching the belt while the measurement is being made, the values measured by the microphone may not correspond to actual values. Do not take the measurement while the vehicle's engine is running. Hold special tool MB992080 to the middle of the belt between the pulleys (at the place indicated by arrow) where it does not contact the belt (approximately 10 - 15 mm (0.4 - 0.59 inch) away from the rear surface of the belt) so that it is perpendicular to the belt (within an angle of ± 15 degree). Press the "MEASURE" button. Gently tap the middle of the belt between the pulleys (the place indicated by the arrow) with your finger as shown in the illustration, and check that the vibration frequency of the belt is within the standard value. Standard value: 98 - 124 Hz NOTE: To take the measurement repeatedly, tap the belt again. Press and hold the "POWER" button to turn off the power supply.
  3. If not within the standard value, replace the auto-tensioner. (Refer to «TIMING CHAIN»(ref-289376-S35593109372008063000000) ).

  2. Remove all of the ignition coils and spark plugs.
  3. Disconnect the all of the injector connectors. WARNING: Keep your distance from the spark plug hole when cranking. Oil, fuel, etc., may spray out from the spark plug hole and may cause serious injury.
  4. Cover the spark plug hole with a shop towel etc., after the engine has been cranked, check that no foreign material is adhering to the shop towel.
  5. Set compression gauge to one of the spark plug holes.
  6. Crank the engine with the throttle valve fully open and measure the compression pressure. Standard value (at engine speed of 200 r/min): 1,090 kPa (158 psi) Limit (at engine speed of 200 r/min): Minimum 650 kPa (95 psi)
  7. Measure the compression pressure for all the cylinders, and check that the pressure differences of the cylinders are below the limit. Limit: Maximum 100 kPa (14 psi)
  8. If there is a cylinder with compression or a compression difference that is outside the limit, pour a small amount of engine oil through the spark plug hole, and repeat the operations in steps from 5 to 7 . If the compression increases after oil is added, the cause of the malfunction is a worn or damaged piston ring and/or cylinder inner surface. If the compression does not rise after oil is added, the cause is a burnt or defective valve seat, or pressure is leaking from the gasket.
  9. Connect the all of the injector connector.
  10. Install the spark plugs and ignition coils.
  11. Use the scan tool MB991958 to erase the diagnosis codes. NOTE: This will erase the diagnosis code resulting from the injector connectors being disconnected.

  8. Disconnect scan tool MB991958 from the data link connector.

TIMING CHAIN ELONGATION VISUAL CHECK

Note. When the timing chain elongates more than the specified length, the diagnosis code No. P0012, variable valve timing (VVT) advanced-angle value abnormal, is output. Unless the diagnosis code No. P0012, therefore, is output, the visual check is unnecessary.

Note. Unless the work using the following scan tool MB991958 is correctly carried out due to the malfunction of ECM, carry out the check whether or not the diagnosis code exists.

  1. Remove all the ignition coils.
  2. Remove the cylinder head cover.
  3. Remove the upper chain guide. CAUTION: Always rotate the crankshaft clockwise.
  4. Rotating the crankshaft clockwise, align the timing mark of camshaft sprocket with the point on the upper plane of cylinder head shown in the illustration. As a result of this, the No.1 cylinder is positioned at the compression TDC.
  5. Look at the inside of timing chain case with one eye in the direction of arrow shown in the illustration. Fix the eye line at the point where the top axis line of the chain elongation indicator at the front side of timing chain case is overlapped with that of the chain elongation indicator at the reverse side of timing chain case.
  6. Check the end top point "A" of timing chain cross section surface and the point of chain elongation indicator which is fixed in Step 5 . When the end top point "A" of timing chain is positioned at the left-hand side of chain elongation indicator, it is unnecessary to replace the timing chain because the timing chain is within the specified length. When the end top point "A" of timing chain is positioned at the right-hand side of chain elongation indicator, it is necessary to replace the timing chain because the timing chain elongates more than the specified length.
  7. Install the upper chain guide. CAUTION: Completely clean the old FIPG remaining in the clearance between the mating parts. Install the cylinder head cover within 3 minutes of applying the liquid gasket.
  8. Apply a 4 mm diameter bead of liquid gasket to the point shown in the illustration. Liquid gasket: THREE BOND 1217G or equivalent product.
  9. Installing the cylinder head cover, tighten the tightening bolt according to the following procedures. Temporarily tighten the tightening bolt in the order shown in the illustration. Tightening torque: 3.0 ± 1.0 N.m Tighten the tightening bolt to the specified torque in the order shown in the illustration. Tightening torque: 5.5 ± 0.5 N.m
  10. Install the ignition coil.
  11. Use the scan tool MB991958 to select the timing chain maintenance. Initialize the learning value. Refer to «TIMING CHAIN MAINTENANCE»(ref-289379-S11700470332008063000000) . NOTE: Carry out the initialization even if the amount of timing chain elongation is normal.
