We have a used 2002 Quest with approx. 93000 miles on it, when is it time to replace timing belt or does it have a timing chain? And when should it have a tune up, new spark plugs, anything else?
Timing belt or chain on 2002 Nissan Quest
IT has a timing belt. If you e-mail me I can email you a preventive maintenance plan. firstname.lastname@example.org
The timing belt must be replaced at least every 105,000 miles, this is an interference engine serious internal engine damage occurs if the belt breaks.
