    Hi, I'm thinking of putting on an electric Meziere water pump, 12V standard duty, and electric fans, Flex-a-Lite 295 dual fan setup, 16-28 amp draw.

    I have a new engine wiring harness, new stock alternator and pretty much new everything else on my car. Will I need to upgrade anything to run the new pump and fan combo or will my current setup be up to the task. Just want to make sure I know what I'm getting into before I find out I need a new alternator and God knows whatever else. Thanks.

    Phil,
    Why??? This is a street car right? Are you having overheating problems?

    No, just trying to free up some horsepower. More, more, more.

    Of course, running more alternator will steal some horsepower.:Brow: But, during most of your driving you don't really need a fan. I rarely turn mine on - my mechanical water pump loves me now that it doesn't have to turn a fan too. A bunch easier to work on the engine too.

    I put a 94 amp 1987 GM 12si alternator on the car this spring - you need the one clocked at 3. The three wire conversion is a milk run - you can do it in a half hour. I wouldn't reccomend a one wire setup since you loose the idiot light and voltage sensing. There is more detail about this conversion on the web site or see George's website for detailed instructions. www.buickperformance.com

    Phil, I just picked up this alternator 135 amp Great deal I thought, Nice deep chrome pulley and black metal fan looks sharp, Called them up for a couple questions they were very helpfull. Fast shipping also. I would also think twice about the electric pump, I had thought they were primarily for racing applications, I would hate to have one die and cook my engine.

    I've never heard of one dying before. I only drive the car 5-7K miles a year. So it should last a good long time.
