    Default Electric Water Pump

    Another spring mod is converting from the ugly mechanical water pump to a hidden Davies Craig electric pump. No more worries about the shift cable rubbing on the pulley! The pump neatly replaces one of the elbows up front. It comes with a controller that varies pump speed with coolant temp, obviating the thermostat.

    The only tricky bit is that I need a tee with 1 1/4", 1 1/2", and 5/8" legs. My fabricator buddy is coming to the rescue, so I hope to post a pic of the completed installation Monday.

    Here is a pic showing where the pump will live (to the right of the fan in this pic).

    Out with the ugly, in with the cool new stuff. Yer always plowing new ground, Jeff.

    I know it's not finished yet, but your picture looks almost like the pump might be sucking water from down from below. Planning to use ground water, Jeff? I can hook you up with a drilling contractor if you need one.

    Hey with once-through cooling why not jettison the ugly radiator and fans too. (There just isn't enough variety in the smile icons in this new forum verion. The variety at PH is awesome.)

    Keep up with the good work!

    Corvetteforum has some good'uns, too. I don't remember if these are on PH.

    For the thread you know will not go well:

    ...overrun timer..I have fitted the DC unit in the past.I think you can get an overrun timer that will help cool a hot water cooled tubo, after engine shut down...

    Even better, make your own overrun timer.

    Et viola. Aluminum tube, same wall thickness as original, so quite light. Beaded on all ends.

    Since I hate rattles as much as the rest of you:



    The squishy foam padding and little square of rubber cost less than 1 ounce.

    Nice work on the new Al tube. Nicely finished and beautiful welds. Too bad it's only visible when you remove the radiator compartment barrier. You might need to replace the black barrier with lexan to show your handwork.

    Is the smaller diameter takeoff for the heater return?
