Ok I have 120000 miles and still going I bought the car with 0 miles and the only problems I've had was a bad fuel pump have not had anything else go wrong I'm surprised this car has lasted me this long with no problems at all. One of the best daily driver I've had 34mpg ftw, now with that being said I'm wanting to put my LS balt down for some serious maintence and daily drive my ss for a while. So what are some things I need to do to my LS at 120k to keep it in good condition. I had noticed that it burns a little bit of oil now but I'm guessing cause the motor is getting older. Here are some things I think I need to change please add to the list

Coolant flush ( same coolant since I bought the car new in 05 have never added coolent ever.)
Water pump
Termostat
Rear drums (never replaced or messed with ever since buying car in 05)
Timing chain?

What's else guys?

 

You mentioned both miles and km so I'm going to assume miles since your from the US... And wow im surprised you have never touched the rear drums and they are still working.. Coolant yes, what about your tranny fluid? If it's the same as coolant and hasn't been touched in awile some suggest leaving it in. Timing chain they recommend around 160k, But my previous 2.2 ecotec is rocking 270km with original chain so they def can go longer. Might think about a higher mileage oil that's thicker. Serpentine belt, Control arm bushing, motor/tranny mounts, brake fluid, power steering fluid.

 

Lol power steering its electric power steering, ya I've never changed the tranny fliud either its a 5 speed

 

I've never heard anyone have problems with the water pump so I'd leve it alone unless something is wrong with it. Not the most easily accessible thing on this car

 

Ok I was just asking because I've notice higher coolant temps now.

 

Well that could be a couple of things. Could be the coolant since yours has never been changed, or it could be the tstat not opening properly.


Edit: And give your car a good seafoam treatment.

 

^What he said. Never had to replace the water pump on this car but I've been working around it before and I know it would be a bitch to get out. Coolant change should help and maybe t stat. You could also get a tune to have your fan on all the time or more often to help cooling.
