'95 240sx SE Tune up List

[base9se]

I have read some of the past forums and they mostly call out the following:

1.) Fuel Filter (91 NA 300zx) 2.) Spark Plugs 3.) Spark Plug Wires 4.) Air Filter (K & N filter cleaner) 5.) Distributor Cap & Rotor 6.) O2 sensor (mine goes bad about every 3 months, http://nicoclub.com/zerothread?id=83959) 7.) Transmission Fluid 8.) Differential Fluid 9.) Oil & Oil Filter (Mobil 1 5W-30) 10.) PCV Valve? 11.) Coolant (already changed) 12.) Brake Fluid (will be changed this weekend)

Am I missing anything else? What brand would you guys recommend? Where can I order some of the parts on the net (cause I really don't have time to find & buy the parts on weekdays)?

list looks good to me, if you want you could do the thermostadt and hoses when you do the coolant, as well as replace the belts, and i would also change the clutch fluid, just make sure no air gets in it, its a pain to get back out. and for parts from the net, check the sponsors on the right, you may have to order from more then one company to get all that stuff

Sounds good to me. For plugs run BKR6E-11 for NA and BKR7E-11 for boosted KA. Flush and fill you PS. Refill with ATF, don't ask why it says that in the FSM. Run Mobile 1 5w30 until 65K miles then run 10w 30 from then on. Also don't forget to flush and fill the radiator and the diff. That is all I can think of.

Run Mobile 1 5w30 until 65K miles then run 10w 30 from then on.

What's the big difference about running 5w-30 than 10w-30? Just viscosity right? Meaning better gas mileage using the 5w-30.

[98s14inaz]

One is thinner than the other. When the engine starts to get older you should use a little heavier oil especially if you drive it like you stole it. An ounce of prevention is worth a ton of cure. You won't even notice the gas milage difference.

[S14Swap240sx]

plus now that the winter is comming ur better off with a thicker oil.. but yea like everyone is saying for old engines dont use thin oils they will leak threw everything

I drive like in GTA... Nah, not really, but I'll change to thicker oil to get ready for the winter months ahead.

if you have a lot of miles a belt and water pump install might not be a bad idea, maybe a fan clutch while you are at it.

[98s14inaz]

Nismo thermostat is a good idea and definitely the belts.

Belts have been done 6 months ago. Water pump changed a month ago. Fan Clutch has not been changed yet. What tell tell signs that it's time for the clutch fan to be changed?

[98s14inaz]

If you can't spin it by hand it is probably shot. It has a viscous coupling that goes after a while.

[sanioll]

Aren't you supposed to switch to thinner oils in low temp during winter. Like 5Wx30 (petrolium)

You gotta use thicker oil in summer when temps rise. 10Wx30 should be fine.

EDUCATE ME if im wrong.

[BadMojo]

I always thought you'd use something like a 5w30 if you lived somewhere very cold. Something like a 10w30 would probably be too thick at cold startups if you live somewhere that can see temperatures too far down below zero. I always run a lighter eight oil in the winter.

As the other poster said, someone please correct me if I'm wrong.

[base9se]

Great now you guys are confusing me:squint . Someone who knows, please reply for a correct justification.

I was just saying as a rule of thumb that if your motor is over 65k miles you should use 10w30 instead of 5w30. The 5w30 is too thin and runs through older motors like prune juice.

Someone page Fred! He's our resident motor oil expert.

[navysnail]

i was just about to say that badmojo and i think 10w-40 is a good all around, but what fred says is what you should do.

inspect the brakes, inflate tires to spec., balance tires, rotate wheels, load test battery, check alternator max amps, flush brake fluid, check all lights, inspect suspention parts.

[base9se]

Brakes was installed today (Brembo Rotors, HPS pads, SPL brake lines, & ATE Fluid). Balanced & Rotated tires also today. As for the suspension, shocks are blown out and I'll be looking for some soon.
