Hello, my name is ***** ***** I'm here to help get your problem solved.

Ask Your Own Ford Question

This most likely means the fan clutch has failed. If the fan is turning as fast as engine speed even when engine is cold this would mean the fan clutch has failed. This is about a $400 job to have repaired at a shop but it will not cause any problems to keep driving as is. My goal is to provide 5 star service so please let me know if you have any questions, thanks.

what is the cost of the fan ?

The fan clutch itself is around $150-$200 then 2 hours labor to replace. Let me know if you have questions, thanks.

What Customers are Saying:

AlvinC answered a question about my Ford truck that only someone with an in-depth knowledge of his subject would have known what was going on.

Rich DUSA

Because of your expertise, you armed me with enough ammunition to win the battle with the dealer. They are installing a fuel filter and fuel pump at no charge to me.

MollyUSA

I needed help with my car on Saturday morning....got a response in 5 minutes, and it was the perfect solution. Thanks again to your service.

Jason V.Kirkland, WA

I do know, after going though this with JustAnswer, that I can somewhat trust my mechanic but I will always contact you prior to going there.

BRNew Jersey

I would (and have) recommend your site to others I was quite satisfied with the quality of the information received, the professional with whom I interacted, and the quick response time. Thanks, and be sure that I'll be back whenever I need a question answered in a hurry.
