    Magnetic sump plug and engine warm up gadget

    Magnetic sump plug.
    Ten Neodymium magnets measuring 5 mm diameter by 4 mm long just arrived all the way from China. Cost less than 10p each inclusive of air mail shipment. http://www.ebay.co.uk/itm/3209688022...84.m1439.l2649

    I centre bored my sump plug to 2.0 mm depth. Glued magnet to plug with standard epoxy two component glue.


    Neodymium magnets are extremely strong but start loosing their strength when exposed to temperatures above 150 Centigrade. My plastic sump would melt at that temperature so I assume I'll be OK with this magnet.

    Engine warm up gadget.
    This gadget fits in seconds. Mine is calibrated to increase engine speed to 2000 or 2400 RPM on the 450 Cdi depending on where on the pedal it is fitted. Stores flat in drawer near car radio.



    Above gadget is made from 1.6 mm diameter ESAB 316L Tigrod. Can also be made from stiff haywire or coat hanger wire etc.

    The gadget is ideal for getting engine quickly up towards operating temperature whilst you clean ice and snow off your Smart.

    Here is an improved version of the gadget:

    Dimensions are in millimetres. Inside or moulded measurements, i.e. air gap from inside edge to inside edge of steel rod.

    The purpose of the 100 degrees angle is to make it easier to remove the gadget. Lower hook will spring loose when pedal is pushed down.

    Drives a Smart Cdi - 65 to 85 MPG

    I particularly like the engine warm up device, I've never found anything quite the right length to wedge on the accelerator to rev the engine gently.

    Mine consists of a suitable length of timber installed between the front of the driver's seat and the accelerator pedal - approx 5000 rpm between seat adjuster notches!

    5000?!?!!?
    I have "nought" to add to this, except....

    You must have similar notches on your headboard too I guess (and those are the "naughty" ones....)

    It doubles as a cruise control.

    It would, if you used a servo from a model plane to push/pull the wire....
    Simple feedback from a propeller mounted on the roof to measure speed.
    Avoids all the cost of getting a code for the official one at least!

    It's not good for the engine to let it tick over or run when cold and stationary.
    Cold starts are when you get the most engine wear so you want the car to heat up as quickly as possible.
    When you drive the car normally, you load the engine which creates more heat and brings the temperature up quicker.
