I have an alumitech radiator with dual spal fans on it. We have it wired up to run with the engine and key off if it is still at above the sensor temp when shut off. Sometimes it runs for a little while before shutting off. Does anyone think this will be ok? We just figured it would be best to cool the motor and aluminum heads (ZZ383) off while sitting there not running rather than holding all the heat. What does anyone think about this? Thanks.
