Derale Flex Fan

When I decide to buy this fan I didn't think it will work. I have a 1982 Mercedes SD200 my problem was that I can't use the air conditioner because the temperature raise to 110 degree in seconds. I install the fan not thinking it will work bat to my surprise it works very good now the temperature doesn't over 100 when I run the air conditioner the only problem I have now is MPG I lost 3 miles per gallon but I can live with that performence.

Good price but center hole too small

Blades look good but the center hole was a tad too small for both water pumps I tried it on. Had to ream out the hole. Good price.

Question about note section on part # 910156-17 Derale Flex Fan The notes section on the website shows Depth from water pump mount towards engine is .94" which is close to 15/16". Is the number suppose to be .094" which is about 3/32". If its the smaller measurement, I think this will work for me, and I will order one. Please let me know. Thanks. Deano
