Would like to know if this model has a timing chain / belt. And what is the time frame to get this replaced ? The cost information would also be great.
Timing chain / belt on 1999 Nissan Altima
All Nissan Altimas have a timing chain, not a timing belt. The chain does not require servicing unless there is a problem. You can find an estimate for the chain replacement here: http://repairpal.com/estimator?car_type_id=2632
