Yep,time to replace it before it locks up or possibly comes loose. Try looking up your specs through Rockauto for the right #

If you are running anything but a stock engine, and on the street, do yourself a favor, and switch to a thermostatic type clutch.They are way better at controlling the water temp. And mine is well over 12 years old and still working. They are only a few dollars more, but to me, well worth it.I'm never going back.
I took my 7-blade fan and pulley down to the jobber, and found a Ford truck one that fit both, and just bolted it in with the correct spacer in a shroud.Some might chuckle at the big fan, but I'm not made of cash.I don't have lot's of loot for a rebuild if my engine cooks. My engine has accumulated more than 100,000 miles, in 15 summers.
