Mk3 supra radiator fans

ok let me decipher... maybe

when you obtained your car you had a new aluminum rad put in.. you have two small fans that are not attached and are causing you concern. you also have a black rounded piece of plastic covering the radiator.. yes?

k.
those two small fans are auxiliary rad cooling fans.. there thermostat controlled (hence the wires.) and kick on when the car reaches a certain temp. are they needed..? They don't hurt.. its always good to have a cooled radiator.
The black piece of plastic covering your rad is called a fan shroud. It directs the air produced by the mechanical fan. (the one attached by pulleys. Hence mechanical (no wires) ) and this is needed to assure proper air flow in the engine bay.. DO you absolutely need it, no. but will see an increase in engine bay temp.

The reason the mechanic took it out is most likely fitting issues due to the new radiator. The increase in cooling you will see by installing them again might be marginal with your aluminum radiator. but if you got room to slide those puppys in there they connect to little connectors on the bottom someplace. give it a check, its been awhile since ive been under my supra.

hope this helped.

OH your shroud should either have one or two openings on the drive side.. those are were the small fans go in.
