Engine Mechanical: Specifications Nissan Pathfinder III

Parts Requiring Angle Tightening

1. For the final tightening of the following engine parts use Tool: Tool number : KV10112100 (BT-8653-A) Cylinder head bolts Lower cylinder block bolts Connecting rod cap bolts Crankshaft pulley bolt (No angle wrench is required as bolt flange is provided with notches for angle 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 nuts and bolts, separate the mating surface and remove old liquid gasket sealing using Tool. Tool number: KV10111100 (J-37228) CAUTION: Be careful not to damage the mating surfaces.
2. Tap seal cutter to insert it, and then slide it by tapping on the side as shown.
3. In areas where Tool is difficult to use, use plastic hammer to lightly tap the parts, to remove it. CAUTION: If for some unavoidable reason tool such as screwdriver is used, be careful not to damage the mating surfaces. (Scheme 1): Identifying Tool

Scheme 3

Scheme 4

1. Using scraper, remove old liquid gasket adhering to the gasket application surface and the mating surface. Remove liquid gasket completely from the groove of the gasket application surface, bolts, and bolt holes. (Scheme 2): Identifying Scraper
2. Thoroughly clean the mating surfaces and remove adhering moisture, grease and foreign materials.
3. Attach liquid gasket tube to Tool. Tool number: WS39930000 ( - ) Use Genuine RTV Silicone Sealant or equivalent. Refer to " «RECOMMENDED CHEMICAL PRODUCTS AND SEALANTS»(ref-272531-S39642641642007112100000) ".
4. Apply liquid gasket without breaks to the specified location with the specified dimensions. If there is a groove for liquid gasket application, apply liquid gasket to the groove. (Scheme 3): Applying Genuine RTV Silicone Sealant As for bolt holes, normally apply liquid gasket inside the holes. Occasionally, it should be applied outside the holes. Make sure to read the text of this article. Within five minutes of liquid gasket application, install the mating component. If liquid gasket protrudes, wipe it off immediately. Do not retighten nuts or bolts after the installation. After 30 minutes or more have passed from the installation, fill engine oil and engine coolant. CAUTION: If there are specific instructions in this manual, observe them. (Scheme 4): Applying Bead Of Sealant To Bolt Holes
