But Bob wrote in his first post that he had already ruined the radiator
completely with the pressure washer.

Aside from the questions being debated about the radiator flowing in one
direction and not the other or if the radiator was even defective or
not. I think it was inappropriate for Fluidyne to do destructive
testing on the radiator Bob sent them with out clearing it with Bob
first. By destroying the radiator they forced him to replace it and
prevented anyone else from testing it in the future. If your supposed to
be doing an investigation you don't destroy the evidence!. Now Bob has
no way to prove his ( and his mechanics) claims. It seems to me that
Fluidyne could test whether their radiator was working as it should with
out cutting it in half. If they found that it wasn't cooling then they
could have asked for permission to do a forensic examination to
determining the reason it wasn't cooling to specs. They had no right to
destroy Bob's radiator with out getting Bob's permission. They owe him a
new radiator just for doing that!

Hmmm? I dunno about this. But I'll let the expert mechanics
duke it out.
But I bought my 1974 Pantera in 2000, it was completely stock,
with 38,000 mi. I always ran a perfect 190deg
(at least that's what the temp gauge said) in traffic or open
road. Even all trips to Las Vegas for POCA every year
with AC full blast with NO overheating. When one of the
original fans gave out I replace both with 5 or 6 blade
(can't remember which) fans and again. never an overheating
problem. Dunno, maybe it's just luck.

Hello All,
Many of you go thru high heat issues with the Pantera.
When I purchased my car in 2008 the previous owner told me if I
was in traffic to just pull over . I was determined to cure this car
from high heat exposure.
The first things I attached on the car was the following:
Replaced Water Pump with Hi Flow Water Pump
Replaced Thermostat ( many times)
Replaced the old brass radiator with an new Aluminum radiator
from Summit.
Replaced Meriah fans with new sucker fans
Replaced antifreeze and purged air from system (many times)
Did complete Tune Up. ( many times)
Now it was time for the big test. I got on the highway and the
car was holding temp at a steady 180. The minute I got off the highway
the temp started rising to the point of boil over. I could hear my
pressure bottle perculating.
This went on for years. I drove the car across the USA in the
Gumball Rally.As long as the car was moving I knew we would be ok and we
made it from Santa Monica California to Miami Beach safely.
The car was still running hot so I tracked down an NOS Pressure
tank and overflow bottle from a place in Modena Italy. I thought maybe
there was something wrong with my pressure and overflow bottles.
My local mechanic replaced the pressure and overflow bottles and
the car started to overheat immediately. The only part to look at now
was the FLUIDYNE Radiator that I had replaced 4 years ago when I
purchased the car.
We let the car cool a little and then restarted the car. My
mechanic said he was going to run water over the front of the radiator
when I started the car. I was in the car while it was running to see if
the water temp would lower as he ran the hose on the front of the
FLUIDYNE radiator. The temp was lowering! . Then he said shut the car.
My Mechanic said that since I had sucker fans my car should have been
sprayed with water when he ran the water on the front of the radiator.
Instead the car was DRY . This meant that the radiator was now allowing
the water to flow through and thus no air could flow through either.
Next step was to reverse the fans to blow out the front of the
car and leave it idling in place . The car ran at a steady 180 for 30
minutes and the temp did not rise. This told us that the radiator was
fault and only flowed ONE WAY .
I could not believe that the radiator could be faulty. I drove
home and cleaned the radiator with a pressure washer and ruined every
fin on the radiator.
Then I contacted the owner of Fluidyne. I explained what we had
done and in summary we felt we had a one way radiator that could only
flow air one way . I also admitted that I had pressure washed the
radiator and ruined the outside fins. Hard to believe but TRUE.
He asked me to send the radiator to him and if they faund any
defect in workmanship he would replace the radiator at no charge. He
came up with every excuse possible. He cut the radiator in half to look
at the internals of the radiator.
Here is FLUIDYNES actual response:
Good Morning Robert,
Further to our investigation:
· Your radiator was inspected upon receipt and found to
be 'bloated' . swollen in the middle of the core, consistent with
symptoms of over-pressurization.
· The fans were tested while installed on the core and
operation was verified. They seemed to pull a reasonable amount of air.
· The fans were then removed and inspected. The fans are
"pusher" fans. not "puller" fans as you were told. [See pic 3 to see
arrow markings]
o They most likely were wired to work as "pullers" but the
performance would be significantly hampered considering the pitch of the
blade is backwards
· The Inlet/Outlet water tank was removed to inspect the
core. Debris was found near the top & bottom [see pic 1 and 2] which
had plugged several tubes.
o This is not a significant blockage but we noted that foreign
debris was indeed inside the core.
· The Return water tank was then removed [pic 4] which
showed a significant amount of engine oil has passed thru the core.
o We suspect this oil was introduced to the radiator by
failure of a cylinder head gasket.
o I appears the oil remained in the core for some time as it
would not wipe off.
o We also assume this failure created the high pressure event
that caused the core to be over-pressurized.
· The Core shows no internal structural damage and the
outside structure [air fin] was heavily damaged as you know and has
rendered the core useless.
Conclusion:
The outside air fin has sustained significant damage and 90% of
the louvers have been bent shut in both directions. The radiator core
appears to be sound. We noted no failures of our Materials or
Workmanship nor evidence of Electrolysis erosion. The
over-pressurization event, while it likely created the 'bloated' shape
of the unit, does not appear to have affected the core's performance.
The only anomaly we discovered was the fact that as installed,
the pusher fans were likely wired to run backwards as puller fans. This
