    I have a 99 Subaru Outback 2.2 L all wheel drive; the thermostat kept blowing out, so we left it out and
    just kept the fluids full. Then, it overheated. We replaced the thermostat again, and changed fluids, got it home and now it won't start. A friend said it was the fuel pump. My mother said it was probably a relay that overheated. How do I figure out what is wrong?

      It sounds like you may have a head gasket issue. This should be diagnosed by your mechanic. It is a hard one to give a definite diagnoses without actually seeing what is going on.
      Hope this helps

      If your A/C system was recently serviced it could have been over charged this could cause these symptoms.
      Or your A/C compressor could be starting to seize .

    Why is there smoke or steam coming from the back of the engine (close to the dash)?
    Whenever I go uphill for a prolonged period (1-2 miles), steam starts coming out from under the hood. It smells like burned rubber, and it seems to be coming from the center back area close to the dashboard.

      Most likely, the issue is a leaking heater core, or leaking heater hoses. Check on-line for the many parts supply sources, such as; or for the replacement parts.

    I have a knocking coming from the front end when making a left turn and giving it gas
    as soon as the wheel is straightened out, it seems to stop. I had a timing belt, air cleaner and oil filter replaced and the boots are ok. This has been going on for a least a year and is getting much worse. Just had 4 new tires put on.

      This sound would be related to the CV (constant velocity) joint of the axle shaft being worn out / excessive play. Time to replace the axle shaft with a new or rebuilt unit. With time and mileage - the sound will only get worse until correctly repaired.

      Try the many on-line auto parts sources, such as; or for the replacement parts. For example, they (Rock Auto) list the drive axle / halfshaft assembly (including the CV joint) for around $41.00 (right or left sides) for your vehicle.

    Why is my car burning mass amounts of oil?
    I have connected my IAC hose to the what i believe is the Valve bleeder hose (hose from drivers side valve cover to intake) on my 98 impreza 2.2. Now my car is burning a ton of oil. Did I break a seal or just draw oil from the valve cover into the engine?

      The 2005 Forester also runs the A/C when the controls are in the defrost position. This helps to dehumidify the heated defroster air for better windshield clearing. So, no matter what the temperture, the A/C compressor will engage with this system when defrosting.

      Confirms what my mechanic told me. The unit would cut out in extreme heat situations. Would shut off and after a while, would work again for a little while. Tried applying oil to the clutch, no difference. Ended up finding a short in the compressor. Replace that and filter. Works fine.

      Check the A/C clutch ass\y, take a screw driver approach the clutch flywheel to feel if magnetic force is there try to suck the screw driver closer. If magnetic force is presented then Google it in Subaru forum, there is a nice write up for how to remove the shim in the clutch ass'y. Good luck. May want to check the pressure switch too.
