Hi All,
I've got a 94 Disco w/108k on the clock. It runs good, but I have an intermittent (sp?) "whirring" sound coming from under the hood. If it's been sitting (long enough for it to cool down, for instance), it'll do it at startup. It's coming from under the hood.
If I up the rpms (still in the driveway), the revs will go up & the whirring sound goes away. That made me think that it was maybe a bearing issue somewhere. BUT, it will come back while I'm driving too.
It kinda sounds like the fan, but not really
Could the fan be my culprit?
I've done the screwdriver to the ear thing & it's not the alt (as I've seen suggested elswhere). What do you guys think? This thing just runs/sounds so smooth when it's not happening.
