Hello all, I have a 67 mustang with a champion 4 core radiator. I am looking to replace the mechanical fan with a thermo setup in time for summer. I have been looking at el/au falcon sets but it appears they are too big for my radiator. As my radiator is 22" (550mm) wide, i might need to go with a single 16" fan setup unless there are any smaller stock dual setups around..

Would appreciate any feedback or advice from those who have installed thermos on their car.

Cheers,
Tony


Cheers, Tony.

I found a fella in VIC who made me up a shroud to the specs I gave him.
He was just selling aluminium sheet, but mentioned in the ad that he can make parts based on your own measurements.

I got two fans with my champion radiator and had this fellow make the shroud for me. I cut the holes myself with a jig saw.

I have heard the ford mondeo fans are a good fit for a mustang. Why not go for a stroll in one of you magnificient wrecking yards with tape measure in hand. I'm sure you'll find something suitable that will look good.

Yes the Mondeo fans are a very good fit for 67's. I just forget which model was the best.

Get a piece of alloy sheet & I'll make a shroud for you. Come in & have a look how I made mine with twin offset fans. My workshop is in Newcastle Street, West Perth. I have a small sheet metal folder in the workshop.

Where does one procure a decent sheet for a shroud?

Look up a steel supplier. They usually carry Al sheet. You will need it at least 1.6mm thick.

I do not like the shrouds like the one pictured or described as they restrict air flow. If you have to mount fans, then mount them on a frame & have a seal around the circumference of the fan to the core Rubber works best). That way it will pull air through the rad when the car is stationary & when the car is in motion, then the rest of the rad will get air flow.

Just my opinion

I used to do it that way... but the down side is that it doesn't use the entire core when you don't have a shroud.

If you have more space, you could make the shroud angled on the edges to flow better. Considering that the fans can pull enough air on their own to keep it cool, I suspect it should flow enough air when the car is moving too, but that's something I will find out.
It was also mentioned to me to use hinged "flaps" that will be pushed open by the air when the car is moving, but close and seal when the fans are running.
So that's another simple option if it does happen to overheat.

XJ jags have rubber flapps on the shroud, the air forced in from the grill pushes them open, and the fan pulls the closed.

Old mate is selling some on gumtree.

The larger one is from an AU and the smaller one is the jag one you guys mentioned. The flaps are a good idea.

I think for my application and given the fact my radiator is 4 core and not very wide, might just stick to having a fan without a shroud. A 16" fan would almost cover the entire core anyway since it is about 19" high x 20" wide.


Cheers, Tony.

400 HP , will idle all day long without getting hot. May not be the tidiest but everyone stands at the front of the car when they look under the hood.....

Sounds like you might as well give it a go... not a big job to change around later if it doesn't work anyway.

dont have ay pics but I did pretty much the same this as dono. Made up some brackets, no shroud. My rad is a X-Flow design but more than keeps things cool. The F100 will get the same treatment

Measured up the radiator last night, the core is 480H x 410W x 60D. A 16" fan will be the perfect size. Just bought a 3000cfm zirgo fan with relays, wiring, adjustable temp switch etc. off ebay for $250. This should be more than enough!


Cheers, Tony.
