First... how much current does the pump draw??
Im thinking itll be a LOT.
Because of this, the light bulb idea and LM317 idea probably wont work.
Using resistors would, but they would be huge and would need to be bolted to the chassis or radiator to act like a heatsink so they dont cook.
PWM is the best idea, but you may have problems with this too.
There is a good chance the motor will need above 60% power to startup, after this you can then slow it back down.
Unless your tricky with electronics, youll need to do this with somthing like that Jaycar PWM Controller kit with a knob on the dash you rotate to full when you start the car and then back off.
I could see this being rather annoying, and you also actually wouldnt know how fast the pump was turning until your engine heats up.
You could also forget to turn it up later and cook the engine.
So i think you should just use it the stock way, or find someone that can build a controller for you that will do it properly.
