    I have been always interested in this with the idea of setting it up on a thermo switch to run when the car gets switched off and the coolant is over a certain temperature to pump the water around until it cools sufficiently. Thought of doing that in conjuction with running the two ac fans for a short period of time.

    I am not really a big fan of Davies Craig stuff these days. I suggest you look for a Mercedes one at a wrecker (or eBay) the quality should be better.



    see eBay:

    "When you car is stilling at a stop light there is not enough circulation in the engine coolant to get hot water moving through the heater core. This little electric motor helps to "push" a consistent water flow through the core. When it fails it kinda creates another problem as well. Not only does it not help push hot water through, but it will actually create a blockage in your heating system. If you heat is dropping off while the car is idling, then this could be the culprit. It is located in the engine compartment between the two firewalls on the 126 in line the the heater hoses going into the fire wall. Find it and with the engine running put your hand on it. You can usually feel the vibration if it is running. It will also leak over time and you will notice coolant loss on longer trips. This item is not difficult to install yourself. "

    Nearly every Merc from mid 1980s will have one 190e's for example
    So many projects - so little time.

    Default Re: bosch/merc pump

    Nope, it wont work. Its a small booster pump only(designed to cut in when stationary in traffic - therefore engine idling) and will not provide the capacity to be to only pump

    [QUOTE=Jack Daniel]Davies Craig Electric Coolant Pump?

    Has anyone tried one of these?

    QUOTE]

    Yes, I have one in one of my race/rally cars (not a french car tho')

    It and the thermo fan stay on even after I have turned off the
    engine/ignition so that when I come into the pits aftera race, or
    have to stop at the end of a stage, I no longer get to listen to
    the coolant boiling in the head after I turn the engine off (heat soak,
    cast iron head/block).

    I have had it on the car for a couple of years now but it is *not*
    a car that has lots of miles of usage (just very hard usage when it
    does get used).

    I am somewhat paranoid so I left the std water pump in place and
    carry the pully, fanbelt etc so that I can convert back if it fails far
    away from a service area.

    It hasn't failed on me yet.

    Would I use it on a car that gets used every day? I'm not ready to
    make that jump just yet.
