Inspection for Leaks
The following are procedures for checking fluids leak, lubricates leak and exhaust gases leak.
●
Before starting engine, check oil/fluid levels including engine coolant and engine oil. If less than required
quantity, fill to the specified level. Refer to
MA-10, "RECOMMENDED FLUIDS AND LUBRICANTS"
●
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 fuel, exhaust gases, or any oil/fluids
including engine oil and engine coolant.
●
Bleed air from lines and hoses of applicable lines, such as in cooling system.

Insert clip into clip mounting groove on fuel injector.
●
Insert clip so that protrusion “A” of fuel injector matches cutout
“A” of clip.
CAUTION:
●
Do not reuse clip. Replace it with new one.
●
Be careful to keep clip from interfering with O-ring. If
interference occurs, replace O-ring.
b.
Insert fuel injector into fuel tube with clip attached.
