The Pacet electric cooling fan is available in two sizes; which you need depends on the size of your engine. The smaller fan (A) comes ready assembled with the motor in its support bracket. The larger fan (B), has first to be assembled, using support brackets (C) and motor (D). Both kits are supplied with a thermal sensor and switch with mounting bracket (E). To secure the fan to the radiator you use the special ties, washers, sponge pads and nuts (F). Extra wiring and terminal connectors with an in-line fuse (G) are supplied to wire the fan up.
