This was the exact spacer needed for a Jeep Grand Cherokee with 4.7L V8. I used a Flex-a-Lite 1518 Fan with an 851 adapter and this spacer for a perfect fit. Very easy installation using a rental fan clutch removal tool and a 12″ adjustable wrench to remove the fan clutch. I did not follow the instructions per the manufacturer. It says to install the adapter and then the spacer then the fan. The bolts with the spacer are the exact length for the installation so I attached the fan, spacer, and bolts to the adapter and torqued the bolts per the manufacturer. The assembly fit easily between the shroud and the water pump and when all was done the position of the fan was exact. The only negative was the adapter is too large for any wrench that I had but because the engine rotation is opposite the adapter thread I tightened the fan assembly by hand and the engine did the rest. Don’t do that if you do not feel comfortable but it is the same principle as installing a saw blade on a table saw. Also, Amazon specifically showed this would not fit my Jeep, but the factory said it would work.The fan works great, really great! It is so much light than the stock fan and there is no big, heavy clutch robbing horsepower. My temp guage shows the engine running cooler and no change when pulling a 5′ x 8′ trailer with appliances.
