REMOVAL SERVICE POINT
 
 
<<A>> ENGINE OIL PRESSURE SWITCH REMOVAL
cautionThe sealant is applied to the bolt. Remove the bolt with care not to break it.
Use special tool MB992118 to remove the engine oil pressure switch.
 
 
 
 
INSTALLATION SERVICE POINTS
 
 
>>A<< ENGINE OIL PRESSURE SWITCH INSTALLATION
1. Completely remove sealant adhering to the engine oil pressure switch and cylinder block threaded holes.
2.
cautionDo not allow sealant to squeeze out to the screw tip.
Apply sealant to the engine oil pressure switch thread.
Specified sealant: ThreeBond 1141J or equivalent
noteInstall the engine oil pressure switch immediately after applying sealant.
3.
cautionAfter the installation, until a sufficient period of time (one hour or more) elapses, do not apply the engine oil or water to the sealant application area or start the engine.
In the same manner as removal, use special tool MB992118 to tighten the engine oil pressure switch to the specified torque.
Tightening torque: 10 ± 2 N·m (89 ± 17 in-lb)
 

 
 
>>B<< KNOCK SENSOR INSTALLATION
Set the connector of the knock sensor to the area shown in the figure, and tighten the knock sensor to the specified torque.
Tightening torque: 20 ± 2 N·m (15 ± 1 ft-lb)
 

 
 
>>C<< INTAKE MANIFOLD INSTALLATION
cautionTemporarily tighten the intake manifold because there is a bolt tightening procedure for the intake manifold, fuel rail and injector protector.
Install the intake manifold and temporarily tighten bolts.

 
 
>>D<< INTAKE MANIFOLD STAY INSTALLATION
Make sure that the intake manifold stay is in intimate contact with the intake manifold and cylinder block boss before tightening it to the specified torque.
Tightening torque: 20 ± 2 N·m (15 ± 1 ft-lb)
 

 
 
>>E<< O-RING INSTALLATION
cautionDo not allow engine oil to enter the fuel rail.
When inserting an O-ring into the injector on the injection nozzle side, use special tool MB992106 to gradually expand the O-ring, and fit it in place.
 

 
 
>>F<< INJECTOR/INJECTOR SUPPORT INSTALLATION
1. Apply gasoline to the O-ring of the injector.
2. Insert the injector into the fuel rail while rotating the injector from side to side, taking care not to damage the O-ring.
3. Check that the injector rotates smoothly. If it does not rotate smoothly, the O-ring may be caught. Remove the injector and check the O-ring for damage. Then, insert it again into the fuel rail and check.
4. Make sure that the protrusion of the injector is at the center as shown in the illustration.
5. Securely assemble the injector to the injector groove and fuel rail collar.
 

 
 
>>G<< FUEL RAIL ASSEMBLY/BRACKET/INJECTOR PROTECTOR REAR INSTALLATION
1. Install the fuel rail assembly, bracket and injector protector on the cylinder head.
2. Tighten mounting bolts together with temporarily tightened intake manifold mounting bolts in the order shown in the illustration.
3. Tighten the fuel rail assembly, bracket, injector protector rear and intake manifold in the order shown in the illustration.
  • Temporarily torque: 3.5 ± 1.5 N·m (31 ± 13 in-lb)
  • Specified torque: 20 ± 2 N·m (15 ± 1 ft-lb)
