How often should a '93 Nissan Sentra with 210K miles have a tune-up?

Answer 1

NowIf you just bought it, NOW and every 24K miles thereafter. Oil change at 4K miles. Timing belt every 60K miles. You should change it NOW if you just bought it. All this is assuming you DONT know the cars maintainance record for certain. if its a 9393 Sentra has a timing chain - no need to change every 60k.

Most Sentra's

Has timing chains as opposed to belts on some cars. You might not need to changed the chains but for an engine with 210k miles, changing it might be a good idea.

From personal experience, timing chain should last for a long time, They use an adjuster that works very well so stretching is not a problem. I had one with 345,000 on it and it ran perfectly. I used Synthetic 5w-20 and changed it every 5000 miles. Platinum plugs changed every 100,000 miles and wires every 50,000.
