Thunderbird cooling fans…

I picked a SPAL Dual 11″ inch fan setup that had some really good reviews. I was gambling that I could make it fit by having the water pump pulley in between the two fan shrouds. Mistake!..

It turns out the setup is too wide for my radiator and to deep for my long nose waterpump. I had to come up with a plan to still use the dual setup as two singles. 

Separating the two wasn’t a problem for a small hacksaw blade. Even with the two pieces apart it was still too wide for the radiator. 

I ended up using a dremel tool to remove portions of the shroud near the inlet and outlet radiator ports. Once I had the pieces removed I was able to use a piece of flat metal to mount the two together and secure to the top of the radiator. That part of the  fabrication came out nicely. I then had to use the plastic”tie downs” commonly sold with radiator kids. Mine happened to be the DERALE brand. I’m not a big fan of these but under the circumstances I don’t have much of a choice until I can lift the car up and work from the bottom. 

My initial temperature test shows that at driving conditions no noticeable difference observed. At idle after driving around the temperature dropped a few degrees than normal. I won’t know the actual benefits until I’ve ridden during the hotter time of the day. All this was going on during the later afternoon hours towards the evening.
