My Radiator and Fans Replacement.........

And then I also acquired a pair of "optional factory 8-blade" fans/cowlings/motors/mounts, with 1 motor needing replacement with destroyed end bearings.
Has anyone here ever seen/heard of/had/been equipped with/used these orange 8s?

The inside bore of the (unobtainable) fan hub was mauled and over size and spinning on the motor shaft, (probably the cause of the other motor's failure) and that made it necessary to drill/tap/double set screw the hub to the new motor's shaft, using the nylock nut to just set the hub level and centered on the shaft.

The cavity was laboriously and completely refurbished/repainted/readied for the install........

And only slight trimming of the side air deflectors was necessary to accommodate the additional core depth of the new radiator during the easy install.

All hoses are extra length and quadruple clamped, and both tubes were cleaned and repainted.
The refill went as expected (4 gallons came out) and since the nose was up anyway, I put 3 gallons of mix in until the upper petcock indicated full, then drop/run/open thermostat/shut off/cool off/add a quart/repeat until it was happy/full/cool.

Really apparent here is the added depth of the radiator core, as well as the deeper fan cowlings for those orange 8-blades.

The fans are quieter, faster, and pump much more air than the stock units, here unsuccessfully hiding behind the newly refurbished/repainted front grille and valance.

It's a shame to have to cover up those new parts, although I did spend a lot of time getting the repaint/patina just right on the upper air deflector.

A much cooler running yellow/black cat is now back to continue prowling the "Valley of the Moon"

Nice work, looks great! And hopefully no cooling issues. Do you know if those temp sensors are set at the same temps as the originals?

Piney:"Do you know if those temp sensors are set at the same temps as the originals?"
Hall now sends 2 75/70c sensors with their radiators and my next task is to revert my wiring back to the stock sensor/relay usage instead of the over riding/overheating/frequently failing/on/off fan switch on the dash.

Thanks!

Thanks for the photos and the narrative of your work.

Do you plan to use both thermal switches, that is the upper tank location controlling one fan and the lower tank location controlling the other (like the stock wiring)?

while you are rewiring, have you considered using an "Aux Run" relay to reduce the current through the ignition swtich?

Looks great!!

That looks really great!

You did a terrific job!

Rocky

PS. I would suspect that using two thermal switches with the same setpoint would in effect switch the two fans on at different times.

The input side would switch the first fan on at 70 Deg C, and then when the system gets hotter, the output side would kick on the second fan as the OUTPUT coolant temp gets to 70 Deg C.

my #6174 came with those 8 blade Fans from new. That was also one of the clues that let me to start an Investigation if it was a factory built GR.3 car ;-) I don't have any photos on file though and the Fans and Motors are in a box somewhere in my storage now. They were in a bad condition and I replaced them with more modern Fans. Perhaps one day I will (inspired by you) bring them back to life.

Great Job

Your new radiator and fans seem to work better than the old setup for sure.

Your car is SO clean in front there, you must have spent some time cleaning things up prior to the radiator/fan R&R.

Nice job. I also had the same fans when I first bought my car. Although I seem to recall mine were yellow not orange. They may have been an early batch.

Good installation Ron, I really appreciate the time spent adding pics & text. Thank you.

The Pantera uses two fans simply because of the shape of the radiator, its wider than it is tall. If the radiator were square in shape the Pantera would use just one large fan. If you look at the situation that way, there's no reason to turn the two fans on at different settings (in stages). It was common in the Euro auto industry back in the days of simpler controls (i.e. when the Pantera was new) to turn dual radiator fans on & off simultaneously. Its easy enough to rewire the relay controls so that one temp switch mounted in the inlet tank controls both fans (relays). The icing on the cake is utilizing a M22 switch with settings complementing the settings of the thermostat in your car. The fan shall actually turn-off during cruising at highway speed, and turn back on during stop & go driving! Straight forward, simple engineering that works like a "normal" car, like it should have 45 years ago.

Hey Ron, Those aren't "optional factory 8-blade fans," They're Ford Cortina fan blades retrofitted to the stock Lucas motors; a popular upgrade in the 70's for the Pantera. I think Hall Pantera used to sell these in the 70's and 80's.

Interesting Goodroc. I hadn't heard of a car coming from the factory with those fan blades. Although I imagine the factory race cars had many minor improvements/upgrades over the street cars.


Anyway, I have the Cortina fan blades on my car and they work well. Here's my radiator replacement and refinishing of the radiator cavity.

Garth, I beleive it was amongst others mentioned in an old Article from POCA Profiles written by Mike Drew.

Mine are also more of an Orange color if I remember correctly. I see you also have those Fairings in the front on either side of the Radiator? On mine they were long gone but do you by any chance have a good photo or could someone draw up a Sketch of them on Paper? I really would like to replicate them as that is one thing missing on my Car.

Garth,
That's a lot of nice work on your install too.
I'm hoping that others will chime in with information about these 8-blade fans/cowlings, for instance, does the difference in color relate to the difference in source? There's lots of other Cortina dna in there already, but could the orange blades mean a DT factory source, and the yellow from Cortinas/Hall?

There's a set of 8 and 10 blade fans on Craigslist right now for the Pantera SF North Bay auto parts section.

The 10-blade on that add is made by SPAL if I recall correctly. It's the blades Hall Pantera had on the Meriah Fans they used to sell. I still have one laying around somewhere.

Ron - Thanks for sharing that page from Wilkinson's catalog. I didn't know the "8-blade optional fan" was a DeTomaso optional part. I learn something new all the time on this forum.

I'll see if I can get a decent pic of them tomorrow.

I think the eight blade fans were standard on the "L" Pantera? My car had them when I got it. Still do.

The entire system works fine.

This is part of the "L" having the cooling "issues" corrected.

The Hall radiator is nice isn't it? It doesn't have all the glitz of the aluminum radiators but it is repairable where as the aluminum is worth $.23 a pound in scrap.

My 74 "L" had the tiny 4 blade fans.

Pantera's are like a box of chocolates. You never know what you're going to get.

The Hall replacement radiator DID look very nice. VERY nice.

The Cortina 8-blade fans and their steel adapters were listed in the Gr-3 & Gr-4 Supplemental Parts Lists for Europe. NOT delivered stock on U.S- spec Panteras sold by Ford but may be on private import Euro cars. Some Cortina fans were yellow, others were orangish. Used as pushers and mounted in the correct direction on Panteras, they may help a little. They were suckers on Cortinas. The fan motors were apparently Lucas for Jaguar & other Brit-cars of the era- if you need parts- possibly on windshield-wiper motors meant for intermittent duty .

No indications on mine that the car was imported. Seems to be a US spec car.

These fans are orange. Strange?

The guy I bought the car from was a plumber. He had shipping tape wrapped around the heater hose in the cabin, which smelled from anti-freeze.

The hose must have been leaking for a while because the floor pan was rusty.

I wouldn't think a guy like that would NOT be smart enough to know to change the fan blades?

Garth, that would be highly appreciated

I have a pair of 10 blade fans I will sell, make offer. I will give away a pair of old OEM fan motors.

A hood tip I'll pass on.........
When reinstalling my hood I found that by only lightly finger tightening the 3 mount bolts and then closing the hood completely into the latch I could then move the hood around to set side/back/front alignments and gaps much more precisely.
With the grille out and the top deflector off, the top bolt (only) can then be tightened from underneath, locking in the hood's position and then release/raise/tighten the other 2.
The other immediate benefit from this adjustment was that both the effort on the lever to release the latch is now greatly reduced, and now only one two handed CPR compression over the top of the hood pin is necessary to close/latch it on the first try, not 2-3 as it was adjusted before.
This may be old news for many here, but it worked for me!.........YMMV

Hey Goodroc, Sorry I haven't gotten that pic for you yet. I tried to take one today, but couldn't get a decent shot through the front grill. But here is a pair for sale on ebay pretty cheap. Jump on them!

thanks Garth, no worries I will definitely keep an eye on those two.
