Re: Temp creep on 454 in my 69
That's a good brand of fan clutch, but how old is it? I've had clutches in the past that seemed to work and passed the newspaper test, but once they were changed the cooling problems went away. It's a $50-75 part. Not that expensive or time consuming to experiment, and it would likely fall under warranty for a return. Call around as Hayden makes their products under different names and one store will sell the same item for significantly more than another store. Also, I think Hayden makes three grades of clutches: Standard, Heavy Duty, and Severe Duty.
