2002 Nissan Sentra SER Tune Up?
Tune-Ups Are Very Simple. Change the Oil, I use Castrol Syntec
10W-30. Flush and change your engine coolant if it hasn't been one
in 5 years(take it to a shop, you really dont save much money doing
it yourself). Also, change the fuel filter if you need to(generally
at 100k mi). Also the air filter if needed. Transmission/Clutch
fluid needs to be done as well. Ensure they are flushed. Many ppl
dont realize how much metal shavings from wear on gears and gunk
build up you'd get in your transission. As long as the transmission
isn't slipping, you dont have to rush it. Also check belts and
pulleys for wear and cracking. The most important thing is spark
plugs. Never trust the igniter gap, even the pre-gapped ones,
they're just a universal estimate. Buy a igniter gap gauge if you
have to. They're usually like $1. Use titanium plugs, like NGK, if
you want optimum performance. Its the little things you do that can
make a big difference in performance.
