It's been a long time, but I have picked them up in junkyards. Look for a late-model full size GM car or truck with a thermostatic clutch unit. Be sure the bolt pattern, shaft length, and fan diameter are correct.

Price should be OK and quality is unbeatable.

well i went to -
NAPA= CHINA & NOTHING LIKE STOCK
ADVANCE AUTO= SAME DEAL
AUTOZONE= SAME DEAL
OREILLY'S= BINGO MADE IN USA, LOOKS JUST LIKE OEM, MADE BY HAYDEN & PART NUMBER HDN 2797
PRICE WAS $44.99 WHICH IS JOBBER AS I HAVE A COMERCIAL ACCOUNT.

HOPE THIS HELPS SOMEBODY OUT

find an ACDELCO supplier in your town. They sell the thermostatic type for our trucks. this type of fan clutch has a wound spring on the radiator side of the fan clutch. The thermocouple type ( I think ) are all junk. I just looked and saw where you tried Advance. Try them again, and find their commercial accounts parts guy. The guys on the retail counter are usually about a sharp as a marble. Advance in my area is starting to stock ACDELCO.

now it gets tough. IF you could get an ACDELCO catalog that has fan clutches in it, there will be a page that shows specifications. I think that there 2 bolt patterns where the fan clutch bolts to the water pump. maybe try and find a fan clutch with similar specs.

So is your new fan clutch for a 350 or 402 or are they all the same? and how can I tell if mine is bad? Thank you. Dave
