Hello, I watched the Cougar video on upgrading the cooling system. I wished I would have seen it earlier. I have a 66 mustang, installed a 67-68 radiator support so I can install a 24 inch radiator. Unfortunately I have already purchased the radiator. The engine will be a 302 (306), AFR 185 cnc heads, 10:1 compression. Adding A/C. I live in the central valley in California, heat is an issue. After watching the video, I am interested in the big block fan with clutch. Do you think this would be the best option? The radiator I purchased is Scott Drake Replacement Radiator 338-2AL .
I will also be interested in a shroud and silicone black hoses. Can you help advise me?
I asked classic cougar and they asked me to post here.
Thank you for your time
Hey Norm,
Hayden fan clutch & a fan from Derale
https://www.npdlink.com/product/engine-cooling-fan-6-blade/141965?backurl=search%2Fproducts%3Fsearch_terms%3DFan%26top_parent%3D210001%26year%3D work quite well for your application. Ive installed 20+ with no issues. Always done after installation of A/C. Fan shroud a must!
So, set lower brackets in place, drill bolt hole, and your basically ready. Silicone hoses… I never liked them, maybe cause they were all blue? Hoses from Gates seem to be the better choice, or the “OE” ones avail in sets w/ old wire clamps & staples holding them.
Hope this helps.
Thank you! They wanted me to adk here because they were not sure about the clearance.
The clearance for the fan should not be an issue. The bigger problem will be adapting a 24" radiator. You will need to trim 2" from each side. The 1966 Mustang only came with a 20" radiator originally. The fan shroud for a 1967 - 68 will also fit the larger radiator and will be necessary.
We removed the 66 radiator support and installed a 67/68 support. Turned out really good, I wouldn’t have thought they were interchangeable. The fan link is for a 17.25 diameter fan. On the mustang sites most of the shrouds they have say the opening is 17. I did find one that is 19, would you recommend going with the 19? Or is there a different one?
Thank you for your help and patience
With the 67 - 68 core support I would use the reproduction C8 fan shroud that is available from any and all of the parts vendors. Not sure what the opening measures but that is the one I would use, along with the C8OEB (big block reproduction) fan.
