Removal and Installation


CAUTION:
- After removing timing chain, do not turn the crankshaft and camshaft separately, or the valves will strike the pistons.
- Before removing the upper oil pan, remove the crankshaft position sensor (POS).
- Be careful not to damage sensor edges.

REMOVAL
1. Remove oil pan (lower) and (upper). Removal And Installation.
2. Remove front timing chain case. Front Timing Chain Case.
3. Remove timing chains and related components. Removal And Installation.
4. Remove water pump, if necessary. Exploded View.
5. Remove rear timing chain case as follows:





a. Loosen and remove bolts using power tool in reverse order as shown.
b. Cut liquid gasket using Tool and remove rear timing chain case.

Tool number : KV10111100 (J-37228)






CAUTION:
- Do not remove plate metal cover of oil passage.
- After removal, handle rear timing chain case carefully so it does not twist, bend, or warp under a load.





6. Remove O-rings from cylinder head and camshaft bracket (No.
1).





7. Remove O-rings from cylinder block.





8. Use scraper to remove all traces of old liquid gasket from rear timing chain case, and opposite mating surfaces.





- Remove old liquid gasket from bolt hole and thread.

INSTALLATION
1. Install rear timing chain case as follows:





a. Install new O-rings onto cylinder block.





b. Install new O-rings to cylinder head and camshaft bracket
(No. 1).
c. Apply liquid gasket using Tool to rear timing chain case back side as shown.

Tool number : WS39930000 ( - )

Use Genuine RTV Silicone Sealant or equivalent. Fluid Type Specifications.

CAUTION:
- For "A", completely wipe off liquid gasket covering the area shown.
- Apply liquid gasket on installation position of water pump and cylinder head very completely.





d. Align rear timing chain case with dowel pins (right and left) on cylinder block and install rear timing chain case.
- Make sure O-rings stay in place during installation to cylinder block, cylinder head and camshaft bracket
(No. 1).





e. Tighten bolts in numerical order as shown.
- There are two type of bolts with different torque specifications. Refer to the following for installing bolts.






f. After all bolts are tightened, retighten them to the specified torque in numerical order as shown.
- If liquid gasket protrudes, wipe it off immediately.





g. After installing rear timing chain case, check the surface height difference between following parts on oil pan (upper) mounting surface.






- If not within the standard, repeat the installation procedure.
2. Install water pump with new O-rings, if removed. Removal and Replacement.
3. Install timing chains and related components. Removal And Installation.
4. Install front timing chain case. Front Timing Chain Case.
5. Install oil pan (upper) and (lower). Removal And Installation.

INSPECTION AFTER INSTALLATION

Inspection for Leaks
The following are procedures for checking fluid leaks, lubricant leaks and exhaust gases leaks.
- Before starting engine, check oil/fluid levels including engine coolant and engine oil. If less than required quantity, fill to the specified level.
- Run engine to check for unusual noise and vibration.

NOTE:
If hydraulic pressure inside timing chain tensioner drops after removal/installation, slack in the guide may generate a pounding noise during and just after engine start. However, this is normal. Noise will stop after hydraulic pressure rises.
- Warm up engine thoroughly to make sure there is no leakage of fuel, exhaust gases, or any oil/fluids including engine oil and engine coolant.
- Bleed air from lines and hoses of applicable lines, such as in cooling system.
- After cooling down engine, again check oil/fluid levels including engine oil and engine coolant. Refill to the specified level, if necessary.
