INSPECTION AFTER INSTALLATION

• Before starting engine, check the levels of engine coolant, engine oil and working fluid. If less than required quantity, fill to the specified level.

• Use procedure below to check for fuel leakage.

• Turn ignition switch ON (with engine stopped). With fuel pressure applied to fuel piping, check for fuel leakage at connection points.

• Start engine. With engine speed increased, check again for fuel leakage at connection points.

• Run engine to check for unusual noise and vibration.

• Warm up engine thoroughly to make sure there is no leakage of engine coolant, engine oil, working fluid, fuel and exhaust gas.

• Bleed air from passages in pipes and tubes of applicable lines, such as in cooling system.

• After cooling down engine, again check amounts of engine coolant, engine oil and working fluid. Refill to specified level, if necessary.
