clutch in your clutch fan is seized, so it's constantly engaged. Not a huge issue. my 76C10 had a constant fan (just ran off the engine RPM's) it's annoying, but it'll be fine. Just get a new clutch assembly for the fan, if it bothers you that much.

I just did my whole cooling system though, new fan clutch and everything though. Why would it make that noise if its new?

[Brian.]

no idea then.

Anyone

[Jeff]

does not meant it is good

[Jeff]

is it oem? the clutch fas should engage when first started then release. it shouldn't engage until it reaches a temperature. does it feel like it is binding up? should have a little tension when its cold but not too much.

Have we thought it could be the VANOS....

?

[e36mpwr]

It's not vanos I otta adjust them because they are ticking or it could be low on oil but ever since I did my cooling system it started making that noise it gets annoying.

[Jeff]

Vanos rattles when its bad. If vanos made that noise i would run its going to blow!

[e36mpwr]

Shop said vanos or you may be low on oil and my check coolant came on so that's probably it.
