PRECAUTIONS
EM-2prose procedureParts Requiring Angular Tightening
Some important engine parts are tightened using an angular-tightening method rather than a torque setting method.
If these parts are tightened using a torque setting method, dispersal of the tightening force (axial bolt force) will be two or three times that of the dispersal produced by using the correct angular-tightening method.
To assure the satisfactory maintenance of the engine, bolts and nuts must be tightened using an angular tightening method.
IMPORTANT
Before tightening the bolts and nuts, ensure that the thread and seating surfaces are clean and then coated with engine oil.
The bolts and nuts which require the angular-tightening method are as follows: (1) Cylinder head bolts; (2) Main bearing cap bolts; (3) Connecting rod cap nuts.
Liquid Gasket Application Procedure
Liquid Gasket Application
- aBefore applying liquid gasket, use a scraper to remove all traces of old liquid gasket from mating surface.
SEM371C - bApply a continuous bead of liquid gasket to mating surfaces. (Use Genuine Liquid Gasket or equivalent.)Be sure liquid gasket is 3.5 to 4.5 mm (0.138 to 0.177 in) wide (for oil pan).Be sure liquid gasket is 2.0 to 3.0 mm (0.079 to 0.118 in) wide (in areas except oil pan).
- cApply liquid gasket to inner surface around hole perimeter area.Assembly should be done within 5 minutes after coating.
- dWait at least 30 minutes before refilling engine oil and engine coolant.
