The cooling system is still way down the line as far
as putting one on the vehicles are concerned.
Initial plans
were to run the FE's, which would require larger radiators than the
small block ones. With original big block radiators fetching a
premium, this was not the ideal way to go. The thought was maybe
to run electric Mark VIII fans on the cars with the BB radiators, but
electrical issues become a concern there and it gets complicated and
expensive fast.
Since the plan is to use a modern powertrain,
why not use a cooling module that was designed for them. The
plan is to use a stock 2003/2004 Cobra unit as they have different
cores to handle the heat generated by the supercharging system. Likewise, a Mustang 2-speed electric fan will be used as well, since this controlled
by the ECU. This should provide more than enough cooling
capacity for our application.
Quick Tips:
- 2003/2004 Cobra and Mach 1 models have a 36mm thick aluminum core,
while the other SN95 units have a 26mm core. They also have
aluminum end tanks, where the others are plastic. The Cobra
and Mach 1 radiators have stamped steel mounting brackets since
mounts can't be moulded into the aluminum like with the plastic end
tanks.
- A V8 Mustangs use the same 2-speed electric
fan. All V6 Mustangs have a single speed fan. The easy
way to tell the difference is to look for the drop resistor which is
located on the fan housing (there is a wire going to it, and from
one side it looks like a small wire coil). The fans are
controlled by the CCRM (Constant Control Relay Module), which is
also different between V6 and V8 models. This
is located under the passenger side fender well on a Mustang.
