I replaced the spark plugs around 115k miles. I do the oil change every 5k miles or so.

The car isn't giving me any major issues currently--- knock on wood that it never does. It does need the catalytic converter replaced soon enough, though.

I want this car to continue running for years and years, miles and miles, boosts and boosts to come.

What preventative steps should I take now that it's hit 120k miles?

Note: I bought the car used and it didn't have the owner's manual.

 

Well i would say the normal spark plugs, oil, coolant, etc not much other than the regular maintenance to do remember that everything inside the engine is a wear part so eventually something has to give. The less abuse you give and the best you can take care of it the better. Maybe not going into boost at low rpms could help

 

Fuel filter
LCA bushings
Ball joints
Strut tops
Tie rod ends
Get the intake valves cleaned up gm has a top engine clean that's real good to use.
I'd replace all the engine an trans mounts also

 

Don't forget about transmission oil. Doesn't matter how good the engine is no transmission no go lol

 

I dont think you can change the fuel filter in a lnf if i remember correctly. Yeah cleaning the valve would be a good idea

 

pretty much keep doing what your doing and put a bigger turbo on it.

like others said clean valves, change fluids, to do the fuel filter you need to drop the tank as the filter is built into the pump.

 

So you would have to change the actual pump to change the filter huh

 

Y would u even have to change the fuel filter in the first place? "If it ain't broke, don't fix it"?

 

Lol i think the lsj had the filter outside the tank and its easy to get to

 

All filters need changing if they're functioning properly.

 

I guess you've never seen a dirty fuel filter

 

in that case why change the oil and filter if its still working, why change anything if its still working?

its called preventative maintenance

 

I am pretty sure the transmission fluid doesn't need to be changed for the life of the transmission from what I've read from GM

 

There''s so much aftermarket parts support for these cars that as long as the body shell doesn't rust out I'll have by Cobalt for a long long time.

 

Lol ok you think that and see what happens

 

100k is about as long as I would let it go. It makes the shifts smooth again.

 

you need to drain out bits of 3rd gear every once in a while

 

 

First of all, if u read my post correctly I wasn't talking about the oil change or oil filter. I obviously understand preventative maintenance but when it comes to the actual fuel filter I legitimately don't know why it would need to be replaced if there's no issues with it. That's all I'm saying... N yes, I have not seen a dirty fuel filter before hence why I'm asking.

 

You really make no sense ^^
Read your own post

 

On the LNF its in the fuel tank so no one is going to be replacing it

If you own a car with a serviceable fuel filter, you should be. Hanging it. Usually every 30-50k miles. My LS was disgusting t 50k. Very easy to service too

 

Maybe u don't understand the difference between oil filter and fuel filter?

 

Good to know, thanks brotha...

 

sell it, buy a Honda

 

Yeah man, something about Chevys and their fuel pumps. The filters always kill the pump in time.
