POSSIBLE

CAUSE

Squeal, click or chirp noise:

• Improper engine oil level

• Improper drive belt tension

Rattle sound noise:

• Loose parts

Hiss sound noise:

• Vacuum leakage
• Loose spark plug

•

Air leakage from intake-air system

Rumble or grind noise:

• Improper drive belt tension

Rap or roar sound noise:

• Exhaust system looseness

Other noise:

• Camshaft friction gear noise or MLA noise

Diagnostic Procedure

STEP

INSPECTION

RESULTS

ACTION

Is squeal, click or chirp sound present?

Yes

Inspect engine oil level or drive belts.

Go to next step.

Is rumble or grind sound present?

Yes

Inspect drive belt.

Go to next step.

Is rattle sound present?

Yes

Inspect location of rattle for loose parts.

Go to next step.

Is hiss sound present?

Yes

Inspect for following:

•   Vacuum leakage
•   Spark plug looseness
•   intake-air system leakage

Go to next step.

Is rap or roar sound present?

Yes
