Review on GM Genuine Parts Engine Cooling Fan Clutch 15-40133 - Improved SEO-friendly product name by Ronnie Staver

Bought for my outrider in the market which my mechanic installed for $350. It was every 4 days and less than 100 miles before we noticed a strange vibration in the engine area. When the hood was opened with the engine running, I saw the fan hover between 1/2 and 3/4 inches. The fan and water pump were new AC Delco parts with an aftermarket cover. I took it back to the mechanic, he said the clutch fan was junk and I had to use the AC Delco for the first time. After another $150 and an AC Delco clutch fan, all is well. It got a 3 for the barrel as it was just installed but didn't wobble or vibrate. Don't skimp on this part!
