Our type 20 radiator is now available. It's the first kit for owners
of 4 cylinders who would like to upgrade the quality and appearance of
their cooling systems. However, the Type 20 is not limited
to 4 cylinder applications. The core size is spec for European
E36 6 cylinders. This configuration allows for additional clearance,
which is required by many aftermarket forced induction kits, while
retaining the 16" fan.
Designed around a high efficiency European core, this
radiator will improve both cooling capacity and safety for
years to come. The type 20 includes a 16" Spal fan that is
rated at 1300 CFM, which is mounted on an alloy shroud. The
purge tank uses our own neck design, permitting a discreet
vent and high performance cap. By running a tube from the
vent port to the exterior of the car, vented gases can
be seen by the driver immediately warning of engine
problems. NASCAR fans will recognize the virtue of this
little trick.
Also, the purge tank is plumbed for a petcock and level
sensor. Note the engine fill line is canted toward the rail
reducing space requirements and smoothing out the flow of
the line. The right tank is fitted with a bung for the
fan control switch.
Finally, this kit replaces the factory plastic shroud,
which increases front engine access--especially in 4 cylinder
applications. The mechanical engine fan and clutch are
also removed, freeing up horse power and reducing stress on the water pump.

Wiring Options
Auxiliary Fan Delete I ( + $62.00 )
This is the recommended approach. With this option, the SPAL electric fan is wired into the existing car harness and
operates on the auxiliary fan circuit. However, to remove the factory auxiliary fan, one must dismantle the front end of the car.
It's a lot of extra work, but the results are worth it.
This package includes the necessary wiring components for
single (high) speed operation.
Auxiliary Fan Delete II ( + $110.00 )
Same as above, but this version includes additional components
for two (low-high) speed operation.
Single Speed Fan Kit ( + $89.95 )
This option includes one wiring kit. The factory auxiliary fan is retained. The SPAL fan operates at a single speed
on its own circuit.
Two Speed Fan Kit ( + $149.95 )
This option includes two wiring kits and a resistor. The factory auxiliary fan is retained. The SPAL fan operates at two speeds
on its own circuit.
