Engine roars. I think it is the fan

Hi,

If the fan clutch is engaged and won't release, it will make noise. Actually, it has been described as a jet engine.

Take a look through this link. It explains how it works.

Also, here is a link that explains common symptoms related to a bad fan clutch:

If you determine the fan clutch is bad, here is a link that shows in general how one is replaced. You can use this as a guide.

You will need special tools to remove the clutch, but most parts stores will lend you the tools. See pic 1 below for tools needed.

I hope this helps. Let me know if you have other questions.

Take care,

Joe
