Checking the technical condition of timing parts
Sprockets, hydraulic tensioner, chain guide and tensioner arm
- 1. Check the camshaft and crankshaft drive sprocket teeth for excessive wear, chipping, and breakage. If necessary, replace the asterisks with new ones
- 2. Check the chain contact surface at the tensioner arm and guide for excessive wear and damage. If necessary, replace with new ones.
- 3. Check the stroke of the hydraulic tensioner plunger and the smoothness of its movement. If any defects are found, replace the tensioner assembly.
Accessory drive belt and pulleys
- 1. Check idler pulley for oil contamination, excessive wear and damage. If defects are found, replace with a new one.
- 2. Check the drive belt for excessive wear. If necessary, replace with a new one.
- 3. Check the pulleys for vibration during rotation. If necessary, replace the pulley with a new one.

Install the timing chain cover.
- - Using a gasket clip, remove the old material from the surface of the gaskets.
- - The places where sealant is applied to the chain cover, cylinder head, cylinder block and ladder frame must not come into contact with oil and ETC.
- - Before assembling the chain cover, liquid sealant must be applied to the gap between the head and the cylinder block.
- - parts must be assembled no more than 5 minutes after applying the sealant. Band width 3 mm.
- - The timing pin of the cylinder block and the timing chain cover hole must be used according to the chain cover assembly order to be in the correct position. Tightening torque: M6 : 7.8 - 9.8 Nm, M8 : 18.6 - 22.5 Nm.
- - Crimping and blowing the timing chain cover must be carried out no later than 30 minutes after assembly
Install the oil pan.
- - Using a gasket scraper, remove the old material from the surface of the gaskets.
- - Before assembling the oil pan, a liquid sealant must be applied between the cylinder block and pan joint surfaces.
When applying the sealant, be careful not to let the sealant get inside the oil pan.
- - After assembly, wait at least 30 minutes before adding oil to the engine.
Install the compressor mounting bracket (A). Tightening torque: 19.6 - 23.5 Nm
Tighten the lower compressor mounting bolts. Tightening torque: 19.6 - 24.5 Nm.
Install the cylinder head cover.
- - Excess sealant extruded from the top surface of the chain cover and cylinder head must be removed prior to installing the cylinder head cover.
- - After applying the sealant, assembly must be completed within 5 minutes. Band width 2.5 mm.
- - Firing and blowing the cylinder head must be carried out no later than 30 minutes after assembly.
- Tighten the cylinder head cover bolts as follows:
- Step 1: tightening torque 3.9 - 5.95 Nm
- Step 2: Tightening torque 7.8 - 9.8 Nm
