INSPECTION AFTER INSTALLATION
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

●

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.
