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 and 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.
