2002 Infiniti QX4 Q&A

2002 Infiniti QX4 Question: approx. how many miles will a timing belt last for 2002 and 2003 QX4s?

have 2002 and 2003 QX4s. 2002 has 133,000 miles, 2003 has 85,000 miles neither auto has had timing belts replaced. Will a warning light appear on the dashboard to tell me when it needs to be replaced? -
Answer 1
No there is no light that tells you. Usually you will hear the belt make noise but inspect it for cuts and wear because if a belt breaks it could instantly ruin your engine. I recommend replacing both. It cost around $20 bucks for a new belt. -

Answer 2
Both of these have timing chains, So no maintenance is needed unless they get noisy or affect the timing -
Answer 3
you do not have a belt, you have a chain, does not need to be replaced as normal maintenance -
