what sensors do you guys recommend to be changed?

i have a 2000 Subaru Outback with 119k.

what sensors, do you think should be changed?

and should any parts be replaced?

also, what should i do to get better gas mileage, change/clean what?

 

They recommend new Oxygen Sensors every 100k.

All the other ones, replace when fail.

 

^~~~Agreed.... unless a sensor is throwing a code, let it be, sensors ain't cheap! O2 sensor is a good idea though. And plugs.....

Check all your fluids (brake, power steering, tranny, etc..etc..)

Should be about it!

 

How about filters?

 

oil, fuel, air. google is your friend. and you need to find out what the factory maint. guide recommends.

 

Says who? Not Subaru that's for sure, maybe your backyard mechanic recommends it.

OP- there is no need to replace any sensor on that car unless they go bad.

However, the common sensors that do go bad around this mileage are the A/F sensor, and the knock sensor. If you have any questions regarding the vehicle, pm me.

 

Fuel filter every 30,000 miles. It is located on the drivers side of the engine bay behind the power distribution box/washer resovior near the firewall.

Air filter- same things every 30,000 or as needed.

Spark plugs get changed every 30k and use NGK's and stay away from the junk champions.

Timing belt gets changed at 105k. This is an interference motor.

Also tires. If one needs to be replace, you need to measure the overall circumference of the new tire on the wheel with a tape measure. Then measure the older tires. If there is a difference of more than 1/4 inch, you should replace the other tires as well or damaged to the Transfer clutches/transfer duty solenoid will occur.

Also watch out for headgasket leaks as well as the older 2.5's are known for leaking headgaskets.
