I am currently using the SPAL 16" Slimline. The flex fan would not work with the Northern Radiator that JSS uses. The fan clutch that JSS suggests in his BOM was 2 close to the radiator. I used a 2013 VVT Truck engine.
where did you put the coolant bottle? Do you have a 5.7 or a 6.4? Did you use Jeep Speed Shop kit or someone elses?
What is the deal with uploading photos? I tried I upload some of mine by dragging them to the upload place it opens the file and then goes away.
