Instruction Manual

1. Using threaded adapters if necessary (included), screw the sensor into the desired
location using Teflon tape to seal the threads. Use Flex-a-lite part no. 32082 (1½” diameter)
or 32084 (1¾” diameter) to mount sensor inline with radiator hose (Preferred location - see
Detail A). Alternatively, the sensor can be mounted in the intake manifold (see Detail
B) or cylinder head or block (see Detail C). Do NOT overtighten.
2. Carefully strip the ends of the wires. Fold the wire back on itself to effectively double
the thickness (
see Detail D). Using a quality crimping tool, crimp the female connectors
provided on the ends. Attach the wires to terminals 10 & 11 on the VSC (it doesn’t matter
which wire goes to which spade, but both wires must be connected). Make sure the temp.
sensor wires are at least 2-3” away from exhaust manifolds or other extreme heat
sources.
3. Start the vehicle and check for leaks. When the engine has reached desired operating
temperature, adjust the VSC to turn the fan(s) on (see page 2).

Detail B
Important:
Before beginning, be sure that the Variable Speed Control unit (VSC) is mounted close enough
to the temperature sensor so that the wires will reach the control unit. The lead on the sensor is
approximately 4 feet.
