INSPECTION AFTER INSTALLATION

Inspection for Leaks

• 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-59, "Fluids and Lubricants"

• Use procedure below to check for fuel leakage.
- 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 check 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.
• After cooling down engine, again check oil/fluid levels including engine oil and engine coolant. Refill to the

specified level, if necessary.

Summary of the inspection items:

* Transmission/transaxle/CVT fluid, power steering fluid, brake fluid, etc.
