What will I be looking at, repair wise, when I have reached 200,000 kms

Not much left at 200,000 Km & your asking
about a 17 or 18 year old vehicle

Is that what you want to work on for the forseeable
future,sort of old

go to www.automecanico. com and translate this amazing website with your browser and fix it.
God bless you

Hi !
200,000 kms is a lot ...
all you need to do is put new piston rings.. this will increase the compression resulting in better performance.

Hi
Wisely speaking you could go for a lower milage OR lower price.....
This deal doesn't look very comforting to me..
But as I have not seen the car ...you could be the best judge..

First try replacing air filter if not done recently $30, next consider bad fuel put in fuel from major oil company from station with many patrons.Then you need to look at fuel delivery system including fuel filter and furl pump. But first try the 2 things mentioned.

Take to a autoparts store, they can run the code on the engine diagnostics (autozone will do for free) and point you in a direction. If it is not self-evident, then report back here with the description of the code.

if its been serviced regularly and had all its fluids changed you can get 200,000 plus out of them easily,in melbourne Austraila(where I live)and old guy has a 94 with 345,000 klms seriously and its only had 2 clutches,but its always been serviced properly.Abuse and lack of service they can last 80,000,you must see service history mever take someones word for it,MOST IMPORTANT,i know as ive had 3 or the same car and i love them

its probably your injectors, does it have over 200,000 kms or been poorly serviced at some time? have you replaced your airfilter? diesel cars also loose compression when their oil is old, and will idle differently and smoke more..

How long the Alero lasts depends entirely on its service history. I assume you mean it has 195,000 kms which is around 121,000 miles and not 195 kms?

You can use this converter to make conversion comparisons between miles and kilometers.

On any car showing this amount of mileage it is absolutely vital that it has a fully recorded and verifiable service history. If not - walk away plain and simple.

if it doesnt keep running then its something else not a fuel filter,i have a car 15yrs old and never changed a fuel filter ,200,000+kms on the original
