Take it to the dealer! It's not a job for the timid or any shop that doesn't know what they are doing. Make sure you get the idler pulleys and automatic tensioner replace along with the timing belt. If the bearings seize in those idler pulleys it will ruin the belt and in turn take out your engine.
with your hands...
its a good idea yes..
Replacing the timing belt is a complicated procedure that is impossible to describe in this small space. The engine in your Subaru is an INTERFERENCE engine. As such if they belt is installed incorrectly and you start the engine you will do damage. I suggest you purchase Haynes or Chiltons repair manual for your car. It will describe in detail with photos how to replace the cam belt.
in with the timing belt change them at the same time
2 plus the timing belt
there is no such thing as timing belt bearings...... are you posibly thinking of an idler pulley? or cam bearings?
Every 60,000 miles is recommended!
105,000 miles
On a 2.5 liter engine it is located behind the timing belt cover.My advise, replace the timing belt when you replace the timing belt. It will have to come off anyway.
It goes by mileage ....100,000 miles is recommended
Yes of course it has a EJ25 Interference engine, if the timing belt brakes the pistons and valves will hit each other.
If you change the timing belt, I would replace water pump as well. Unless it's not working I would not replace it....
