Engine Mechanical (Hybrid): Specifications Nissan Altima L32

Parts Requiring Angular Tightening

1. Use an angle wrench for the final tightening of the following engine parts. Cylinder head bolts Lower cylinder block bolts Connecting rod cap bolts Crankshaft pulley bolt (No angle wrench is required as the bolt flange is provided with notches for angular tightening)
2. Do not use a torque value for final tightening.
3. The torque value for these parts are for a preliminary step.
4. Ensure thread and seat surfaces are clean and coated with engine oil.

Scheme 1

1. After removing the bolts and nuts, separate the mating surface and remove the sealant using Tool. Tool number: KV10111100 (J-37228) CAUTION: Be careful not to damage the mating surfaces.
2. In areas where the cutter is difficult to use, use a plastic hammer to lightly tap (1) the cutter where the RTV Silicone Sealant is applied. Use a plastic hammer to slide the cutter (2) by tapping on the side. (Scheme 1): Inserting Tap Seal Cutter CAUTION: If for some unavoidable reason a tool such as a flat-bladed screwdriver is used, be careful not to damage the mating surfaces.

Scheme 4

1. Using a scraper, remove the old Silicone RTV Sealant adhering to the gasket application surface and the mating surface. Remove the sealant completely from the groove of the gasket application surface, mounting bolts, and bolt holes.
2. Thoroughly clean the gasket application surface and the mating surface and remove adhering moisture, grease and foreign materials.
3. Attach the sealant tube to the tube presser. Use Genuine Silicone RTV Sealant or equivalent. Refer to " «RECOMMENDED CHEMICAL PRODUCTS AND SEALANTS»(ref-278349-S23031461272008012700000) ". (Scheme 2): Identifying Scraper
4. Apply the sealant using Tool without breaks to the specified location. Tube presser WS39930000 ( - ) If there is a groove for the sealant application, apply the sealant to the groove. As for the bolt holes, normally apply the sealant inside the holes. If specified, it should be applied outside the holes. Make sure to read the text of this information. Within five minutes of the sealant application, install the mating component. (Scheme 3): Applying Sealant If the sealant protrudes, wipe it off immediately. Do not retighten after the installation. After 30 minutes or more have passed from the installation, fill the engine with the specified oil and coolant. Refer to " «FLUIDS AND LUBRICANTS»(ref-278355-S32154069652008012700000) ". (Scheme 4): Applying Bead Of Sealant To Bolt Holes CAUTION: Follow all specific instructions in this article.

Tightening Intake Manifold Bolts and Nuts

1. Tighten in numerical order as shown.

Identifying Intake Manifold Gasket. Scheme 5

Installation of Electronic Throttle Control Actuator

1. Tighten the bolts of electronic throttle control actuator equally and diagonally in several steps.
2. After installation perform procedure in "INSPECTION AFTER INSTALLATION".

Scheme 6

Scheme 7

1. Make sure no foreign substances are deposited in and around the fuel tube and quick connector, and there is no damage to them.
2. Thinly apply new engine oil around the fuel tube tip end.
3. Align center to insert quick connector straight into fuel tube. Insert fuel tube into quick connector until the top spool on fuel tubes is inserted completely and the second level spool is positioned slightly below the quick connector bottom end. CAUTION: Hold at position "A" as shown, when inserting the fuel tube into the quick connector. Carefully align to center to avoid inclined insertion to prevent damage to the O-ring inside the quick connector. Insert the fuel tube until you hear a "click" sound and actually feel the engagement. To avoid misidentification of engagement with a similar sound, be sure to perform the next step. see scheme 29: Inserting Fuel Tube Into Quick Connector
4. Before clamping the fuel hose with the hose clamp, pull the quick connector hard by hand, holding at the "A" position, as shown. Make sure it is completely engaged (connected) so that it does not come off of the fuel tube. NOTE: Recommended pulling force is 50 N (5.1 kg, 11.2 lb).
5. Install quick connector cap on quick connector joint. Direct arrow mark on quick connector cap to upper side (fuel hose side).
6. Install fuel hose to hose clamp. see scheme 30: Identifying Arrow Mark On Quick Connector Cap

Scheme 8

1. Make sure no foreign substances are deposited in and around the fuel tube and quick connector, and there is no damage to them.
2. Align center to insert quick connector straight into fuel tube. Insert fuel tube until a click is heard. Install quick connector cap on quick connector joint. Direct arrow mark on quick connector cap upper side. Install fuel hose to hose clamp. see scheme 31: Inserting Quick Connector Straight Into Fuel Tube

Tightening Exhaust Manifold Nuts

1. Tighten the nuts in the numerical order shown, to specification. see scheme 35: Identifying Exhaust Manifold Nuts Tightening Sequence
