99 sentra GXE with GA16de motors have timing chain I believe.
I have a 2001 Nissan Sentra SE and it was suggested I change it every 100,000 miles.
Depends on the year. On any Sentra made in the last 10 years change the spark plugs every 100,000 miles unless you have a misfire. In that case change them immediately. On an older Sentra change them every 75,000 miles.
I drive a 2000 Nissan Sentra GXE. Currently I have about 145,000 miles on it. I spoke to my mechanic regarding this and he said since its a chain, it never needs to be changed. No change is required.
every 20-25000 miles
My 2001 Nissan Sentra GXE gets right around 30 MPG.
