Stock cooling fan cracked on 5.0 – what to replace it with? Reply #15 – February 22, 2017, 04:30:47 PM Quote from: V8Demon;459382The full open temp will vary depending on Manufacturer and style.The 180 in my Cougar is fully open by 185... I tested it before I installed it. It's a Mr. Gasket. I've always had good luck with their t-stats.That being said, I'll agree with Haystack. If you're still running stock heads and cam, you do not need a 180 degree thermostat in a Windsor motor. Side note:. The S197 4.6 3v comes with a 180 degree thermostat from the factory.I've got a 180* Super Stant. Starts to open at 180*, fully open at 190*. I agree at stock SO/HO 5.0 should run a 190* thermostat. With aluminum heads/cam/intake and 3.73 gears the 180* thermostat works well in my application. Quote Selected

I returned it to O’Rielly’s but do you think they just have the wrong part fitment in their catalog? If I was smart I would have not thrown the bad clutch out, so I could see if the holes line up with the new one. Quote Selected

I’m assuming the parts store gave me the wrong one, since they do not seem to have their shiznit together. Before I buy another from a different chain, I was wondering if there could be something I missed. Given the fan blade holes are aligned on the old and new fans, I think not. Quote Selected
