Parts Requiring Angular Tightening

1. Use an angle wrench for the final tightening of the following engine parts: Cylinder head bolts Main bearing cap bolts Connecting rod cap nuts 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 old liquid gasket using Tool. Tool number: KV10111100 (J-37228) CAUTION: Do not damage the mating surfaces.
2. In areas where the Tool is difficult to use, use a plastic hammer to lightly tap (1) the Tool where the liquid gasket is applied. Use a plastic hammer to slide (2) the Tool by tapping on the side.

Scheme 4

1. Using suitable tool (A), remove old liquid gasket from the application surface and the mating surface. Remove liquid gasket completely from the groove of the liquid gasket application surface, mounting bolts, and bolt holes.
2. Wipe the liquid gasket application surface and the mating surface with white gasoline (lighting and heating use) to remove moisture, grease and foreign materials.
3. Attach the liquid gasket tube to the suitable tool. Use Genuine RTV Silicone Sealant or equivalent. Refer to " «RECOMMENDED CHEMICAL PRODUCTS AND SEALANTS»(ref-657649-S00980510722014092100000) ".
4. Apply the liquid gasket without gaps to the specified location with the specified dimensions. If there is a groove for the liquid gasket application, apply the liquid gasket to the groove. Normally apply the liquid gasket on the inside edge of the bolt holes. Also apply to the outside edge of the bolt holes when specified in the procedure. Within five minutes of liquid gasket application, install the mating component. If the liquid gasket protrudes, wipe it off immediately. Do not retighten mounting bolts after the installation. Wait 30 minutes or more after installation before refilling the engine with engine oil or engine coolant.
