Default My electric fan sounds like a shuttle re-entering

When the electric rad. fan kicks in (usually only when the A/C is on), it seems to serve its purpose but it is LOUD!

It's loud enough I sometimes shut the air off a few minutes before pulling up to friends to avoid embarrassment.

It doesn't sound like anything is rubbing, no funny smells, just sounds like a very loud fan.

Do I probably just need to replace it, clean it, or do they all sound that loud?

Default Pretty normal, I think

Is it hot where you are? I remember my 2.8 sounding like a 747 when I ran the AC.

Default It is hot (Florida)

and it sounds like a 747.

I may seek an aftermarket alternative.
Now, to find the stock CFM so I can find a quiet alternative that at least matches it so I don't have any cooling issues.

Default Is your auxilary fan working (the electric one on the engine side of the radiator)?...

This fan is commonly blocked by a piece of rubber shrouding. When it stops, it causes the eletric fan on the front of the radiator to work overtime - hence the air raid siren. If it is indeed blockage of the aux fan, it needs to be cleared quickly before the fan/modulator is damaged

Default You speaking of A/C belt behind glovebox? If so, this is normal, open up compartment

and apply belt dressing. Mine comes and goes, usually after running for long periods, I just turn it off when it squeels for a few minutes then kick it back on with no noise. Sooner or later I will open it up and semi cure it, there is alot of talk about this is the archives.

"Engine" side radiator fan is definitely operational.
