[DeTomaso] cooling fans

[Mike Thomas]

I have a set of the Meriah fans I'd be happy to pass along.  $50+ shipping
and they're yours.

Hit the EASY button.   Several of the vendors sell Meriah fans which fit in 
the stock location.   (Some of them will even sell used ones, cheaply, as 
they are busy selling high-powered sucker fans, the latest fad).

The Meriah pushers move plenty of air and are a great improvement over the 
stock fans.   They work better (spin faster) if the fan circuit is modified 
to provide a clearer current path, including grounding the fans at the body
with diodes (rather than using the stock ground wires which loop all the way
back under the dash).

Here are some links to some new fans.   They're expensive new!

You find them on E-bay from time to time; my girlfriend got a used set from
Wilkinson for a song, $80 or something like that I think.

Another alternative is the Flex-A-Lite dual sucker fan package.

By happy coincidence this setup fits perfectly behind a stock Pantera 
radiator.   However, the stock radiator inlet and outlet pipes have a
90-degree 
angle so the hoses sit right against the back side of the radiator; they
have to be modified with straight necks so that 90-degree rubber hoses can
be 
used.   I think the Fluidyne radiator has straight necks however?

You'd have to ensure that the fan shroud was mounted properly, meaning NOT
with the included zip ties which just pass through the fins of the radiator,

and act like little saws to cut holes in the tubes and ruin it.   You'd 
want to fabricate brackets to mount the fan shroud to the back of the
radiator. 
  You'd also want to re-wire the circuit as per the above.

An article on rewiring the fans (and headlights) can be found at 
www.panteraplace.com.   Although I'm credited with writing it, I did NOT
come up with 
the idea; instead I packaged other people's (great) ideas into a single
article.

Both my girlfriend and I have the Meriah pusher fans in our Panteras, and
both of them resolutely refuse to overheat--and that's with no BS hood vents

or any other tricks.   Just a good, solid radiator, Meriah fans, properly 
tuned engines, decent water pumps, and (most important) thorough bleeding to
eliminate all trapped air from the system.

Good luck!

Mike
