My MC will be approaching 73,000 soon and I was wondering what are some things i should be doing as far as maintenance??? My MC didnt come with an owners manual so I was wondering what things should I do when it reaches a certain amount of miles because I want to get my car to at least 150,000

 

Not sure what people suggest based on miles but after winter I'm getting trans fluid and filter changed, radiator flush and new antifreeze, supercharger oil changed, new rotors, oil filter and change, plugs and wires, and a few other things. I know some of that is more than normal upkeep but thats what I had in mind.

 

Just don't drive it hard. Change the oil when you are supposed to. Check all your fluids frequently.

Etc. Etc.

Mine is over 180,000 miles, so 150k is easyyy

 

the 3100/3400/3800 engines GM put in many of their cars are pretty good. As Chibi said, the mileage you want should be a piece of cake.
Here's somethings to consider:
- Trans fluid and filter change depends on your climate AND driving terrain. Areas with lots of up hill climbs, this change should be sooner then later. I live in Ohio, lots of flat land. I change my fluid/filter every 100,000 miles (my '94 Grand Am got it's second change this spring, it has over 210,000 on it today).
- GM uses iridium plugs these days. Rated to last about 100,000-150,000. We bought an '05 Impala with 150,000 on the factory plugs, no problems, I changed them anyways (cheap insurance to keeping good MPG and performance). Do NOT use BOSCH plugs (BOSCH wires are OK, but plugs should NOT be put in a GM), they don't last like they should and have been known to begin having performance problems in 6 months. AC Delco or I recently tried NGK Platinums in the Impala (turns out the stock plugs where AC Delco branded NGKs).
- Air and Fuel Filters
- If you don't know when the coolant was last flushed, flush it.
- Not a bad time to get the MAF cleaner spray and clean it PER THE INSTRUCTIONS ON THE CAN.
- Inspect the serpentine belt (if it's original, change it)
- Get something like a turkey baster and suck out the brake fluid and power steering fluid from their reservoirs as lower as you can go and refill with clean fluid. Not the same as a full flush BUT better then leaving that old fluid in there.
- Change the upstream O2 sensor (stick with AC Delco or Delphi). I would not concern myself with the rear O2, as it does not affect the performance.

Should give you more then you wanted to do as we enter the winter season.

 

Agree with mike just normal maintance & check ur fluids

 

I have a chart of GM factory recommended maintenance somewhere that I'lll try to find. I got it from the software that my dad has from the shop, it's pretty freaking awesome to have. I'll post what it says on here once I find it

 

Ok thanx i hope you find it!

 

I found a PDF online of the entire owners manual and downloaded it. Also if you set up a profile on auto zone's site they have the my zone section. They have all the maintenance intervals and even send service reminders sent to your email.

 

The only thing that hasn't been said so far that I can think of is changing your fuel filter, and that's normally not a big deal.

 

As long as your fuel lines aren't rusty, it's a piece of cake.
