    Timer for pusher fan

    Hi
    I have fitted an electric pusher/blower fan with a on/off switch for when I am in slow traffic and for when I turn the engine off. Is it possible to fit some kind of 12v timer into the circuit so that when I park up and walk away from the car the fan will switch off after a preset time? Any one know of a suitable timer?
    Thanks
    Steve

    Derale #16759 Adjustable Fan Controller. A good one. Available @ Amazon, Summit Racing etc. Works like a charm. I replaced 3 or 4 cheapos until this one.

    Give Merlin Motor Sport a ring over at Castle Combe they seem to have a range of product that may suite.

    Steve,

    My TR7 had Air Conditioning with a heave York compressor. Seeing little use for this old system, I removed all the air conditioning components as well as the puller engine-mounted fan from under the hood and left the 2 auxiliary fans. These auxiliary fans were mounted on an upward angle in front and below the radiator so as not to block air movement through the radiator when the car is moving forward. Additionally, and specific to your objective, these fans are thermostatically controlled (on and off) with a sensor on the upper tank of the radiator.

    As I remember, there is a plug on the bottom of the top tank of the Healey's radiator. If you can get an adjustible thermostatic switch that can be made to fit into that opening, you can adjust the control to start by a set temperature or manual switch and automatically turn off when the engine temperature drops to a set temperature.

    Just a thought,
    Ray(64BJ8P1)
