The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.
Condition / Concern
A whine noise from the front of the engine may be experienced if the balance shaft tensioner has ratcheted out, causing the balance
shaft chain to be too tight. In rare instances the balance shaft tensioner will ratchet out during service of the cylinder head, timing
chain or if the water pump is replaced without using the water pump sprocket holding tool (J43651 / EN-43651). This will cause the
balance shaft chain to be too tight, which can cause a whine noise from the front of the engine.
Recommendations / Instructions
Before attempting repairs, ensure that the noise is definitely abnormal by comparing the noise to other known good vehicles. If the
noise is abnormal and the noise was not present previously, the balance shaft chain tensioner may need to be reset or replaced.
Follow eSI repair procedures and reset/replace the balance shaft chain tensioner as needed.
Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved
without completing every step, the remaining steps do not need to be performed.
