2003 Cavalier maintenance schedule

Surely your not waiting for 90,000 miles
to do all sorts of things
By then you should have changed your transmission
& power steering fluids at least 2 times & flushed your
brake fluid every 2 years on all vehicles
I do Air,Cabin,Fuel Filter & Spark Plugs every 3 year
What your asking is Manufacture Recommended Service
Wait on that you will either break down or have a vehicle
that won't last much past 100,000
The question you ask is in your owners manual
You need a vehicle Log Book
You need to develop your own Preventative
Maintenance Schedule based on time as well
as mileage & forget the manufacturescheduled
maintenance,your schedule will include theirs
& much most based on your lifetime of knowledge
& experience & repairs
You treat ALL Vehicles the same
It's not a wait & see game
It is about education & preventing problem
down the road
No vehicle manufacture really care what you do
or they would tell you about power steering,brake
fluid & stop with the silly 100,000 spark plug & trans
fluid changed,by then the damage will be done

you must see your owner manual.and download in this you will see with many details how many miles, you will do it.

God bless you

Just to be clear, your maintenance light has illuminated and not the check engine light (CEL) . a CEL indicates that the car has detected a problem of some kind and depending on the severity of the fault it may be harmful to continue driving.

If it is the maintence light then that is easy. It is automatically set to come on at predetermined mileage marks to remind you to have the car serviced.

The maintenance required light is a reminder to bring the car in for scheduled maintenance (every 10,000 miles). The light will flash after start up for 10 seconds once you are 2000 miles from the car's scheduled maintenance. Once you pass the scheduled maintencance mark (every 10,000 miles) without having the maintenanced performed and/or the light reset by the dealer, it will remain on forever unless reset.

To reset it yourself
Hold down the trip meter button, turn the car to on, wait about 20 seconds, start the car, and let go of the button. Light is reset until the next mileage interval.

*make sure lo beam headlights are turned OFF during the procedure*

The 100K schedule repeats continually.
What needs to be done at 50K and 100K, then needs to be repeated at 150K for example.
The schedule only needs to go out to the longest delayed item.

It has a belt, and it is supposed to be done at 60,000 miles. It is a job but it can be done by a patient owner. You can't rush it, you will need the book, a Haynes manual or something like that. the shop will charge about 3 to $400 for it. I think the water pump gets done and the belt tensioner, not sure. Check it out, Hope this helps.

the next scheduled maintenance should be at 50,000 miles and the car should be under warranty still.

90000 MILES IS SCHEDULED MAINTENANCE INTERVALS.

The only other things would be to check the air & cabin filters to make sure they're still clean enough. The scheduled maintenance on those is 50,000 miles.

Did you try looking up something like "90,000 mile Envoy maintenance schedule" and see what the recommendations are? I know I would ask " How much is this going to cost me?" :0)
