Parts Requiring Angle Tightening
- Use the angle wrench [SST: KV10112100 (BT8653-A)] for the final tightening of the following engine parts: Camshaft sprocket (INT) bolt Cylinder head bolts Main bearing cap bolts Connecting rod cap bolts Crankshaft pulley bolt (No the angle wrench is required as bolt flange is provided with notches for angle tightening)
- Do not use a torque value for final tightening.
- The torque value for these parts are for a preliminary step.
- Ensure thread and seat surfaces are clean and coated with engine oil.
Scheme 1
- After removing mounting nuts and bolts, separate the mating surface using the seal cutter [SST: KV10111100 (J-37228)] (A) and remove old liquid gasket sealing. CAUTION: Be careful not to damage the mating surfaces.
- Tap the seal cutter [SST: KV10111100 (J-37228)] to insert it (B), and then slide it (C) by tapping on the side as shown in the figure.
- In areas where the seal cutter [SST: KV10111100 (J-37228)] is difficult to use, lightly tap the parts using a plastic hammer to remove it. CAUTION: If for some unavoidable reason tool such as a screwdriver is used, be careful not to damage the mating surfaces.

- Using a scraper (A), remove old liquid gasket adhering to the liquid gasket application surface and the mating surface. Remove liquid gasket completely from the groove of the liquid gasket application surface, mounting bolts, and bolt holes.
- Wipe the liquid gasket application surface and the mating surface with white gasoline (lighting and heating use) to remove adhering moisture, grease and foreign materials.
- Attach liquid gasket tube to the tube presser (commercial service tool). Use Genuine RTV Silicone Sealant or equivalent. Refer to " «RECOMMENDED CHEMICAL PRODUCTS AND SEALANTS»(ref-516389-S27688368402012120600000) ".
- Apply liquid gasket without gaps to the specified location according to the specified dimensions. If there is a groove for liquid gasket application, apply liquid gasket to the groove. As for bolt holes (B), normally apply liquid gasket inside the holes. Occasionally, it should be applied outside the holes. Check to read the text of this manual. Within five minutes of liquid gasket application, install the mating component. If liquid gasket protrudes, wipe it off immediately. Do not retighten mounting bolts or nuts 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.
