So…just finished installation of the Daniel Carpenter repo fan shroud on 1970 Cougar with 24" radiator. 5 blade flex fan, no clutch - has about a 3" spacer on the fan. Fan is about 1 1/2" off the face of the radiator, nearly completely enshrouded - blades rub on the bottom.
Anybody use one of these shrouds before? Does it actually “fit” (fits to radiator fine) - Do I have to change the fan set-up? A/C has been removed. Any feedback appreciated.
I’m using the same shroud on my 70, and my 7 blade thermostat fan is centered in the opening. Is your radiator sitting all the way down in the mounts? Some of the repro radiators have a fatter tank that won’t slide all the way down in the mounting saddles.
I believe so; my radiator is a FoMoCo unit. I will check that though. I’m thinking the easiest way out is to buy a “different” spacer. How far is your fan from the radiator? (Thanks for the quick response – for now I have “just walk(ed) away…”)
Yep, it’s tight to the bottom mount.
My fan is also 1 1/2” from the radiator core. The round shroud fan opening at the bottom is about even with where the bottom tank solders to the core, but the opening at the top is about 2” above where the top tank solders to the core. Sounds like maybe my shroud is mounted higher than yours.
I appreciate the data Craig. Do you know the diameter of your fan? Mine is something in the vicinity of 17 1/2".
Yup, my fan also measures 17 1/2” diameter. The center of the fan shaft measures 10” below the top of the shroud.
…but mine is a convertible, and I believe the motor mounts are a bit different than in a hardtop.
Thanks for the help Craig. I’ve got the shroud unbolted again, but it looks to sit just like yours does, about 2" above, nearly even at the bottom (to tank welds).
Another option as you pointed out is to shim up the motor mounts…nah.
I could gain about 1/4" to 3/8" by modifying the shroud mounting points, but it is practically laying on the cooling lines and petcock as it is. I’m thinking the issue might be the spacer (2 1/4"), if I go to a 2 3/4" it will move me to about an 1" from the radiator and still approximate 1/2 in 1/2 out on the fan relative to the shroud opening. It’s either that or looking for a 16 1/2" fan.
Ugh, it never fails to amaze me how quick even the simplest task can get complicated. For what it’s worth, my fan clutch puts the rear fan mounting surface out 1 5/8” from the pulley. My shroud bottom is also sitting right on top of the trans cooler lines.
That is beneficial as well, thanks. I was going to ask what the distance was from the face of the fan back to the mount, this figure will get me there. 100% correct on “simplest task complications” - I’ve come to expect it (which might be part of the problem). Replaced a toilet bowl yesterday and turn the supply line back on and I get water leaking out of three places; par.
I’ll get back to the shroud with a fresh mind tomorrow. There’s going to be a solution.
Is your 70 a convertible? I had that problem with the one I used to have. The mounts were collapsing and needed to be replaced. It was fixed by replacing the frame brackets and using coupe mounts.
No convertible; standard coupe. Indications would be my radiator is sitting to high, or my block is sitting too low - motor mounts have been replaced. Thanks for the insight.
I may try to make some “extenders” for the shroud mounts, possible make reliefs in the shroud to accommodate the cooling line fittings and petcock (if necessary). Before that though I will have a good long look at the situation, I believe the car had a front end collision at one time and that may have “modified” the radiator mount…
Some combination of both those things could certainly explain the issue.
The NPD 8146-5 Fan shroud (shows to be a Daniels Carpenter) bolted right in on my 70 351C-4V and clears a somewhat larger 7 blade “big block” fan with a thermo clutch. A failed motor mount took out its predecessor. Replacement OEM style radiator. Not a convertible.
Yep, that’s the one. Thanks for the confirmation. I am minus the clutch, but under the circumstances shouldn’t be an issue. Thanks for the confirmation - it rained pretty much all day today so I have not returned to the project (even though it’s under cover, rainy days make me lazy…)
