noise V70-XC70 1998

posted by  someone claiming to be peter on  Tue Aug 5 10:59 CST 2003 [RELATED]

Upon starting the engine cold I hear a noise coming from the side of the engine opposite the timing belt and pulleys. It stops after a minute or so then it clicks back on as if it is thermostatically controlled. I have checked the fan but it is not comiong from there. It sounds like a bearing whine. It does not sound like the AC, what else is there on that side of the engine.

    It is probably the air pump. Good description here:

      indeed. i've replaced mine once in 184k mi and the used one i installed is going again. sounds a bit like a mini turbine. it usually runs for about 1-2 min after the car gets up to 10 or 12 mph. and then after medium to long runs at highway speeds when you slow or stop. btw, not a big deal to replace - it's bracket mounted right under the battery.
