External coolant tank

  1. #1
    I have made the swop to the 1.5D radiator for my Turbo setup and rejigging the engine bay slightly..

    I want to mount an external slim line tank (most likely alloy) by the passenger headlight.



    My question is would a 350ml 4 port tank be enough? or should I go larger 500ml / 1litre?

    Has anyone fitted one and can give their views etc?


    Or does anyone know of a fairly slim tank from another car (made of plastic etc so you can see the level easier) which could possibly fit? (Please note I don't want to relocate the ecu to fit the saxo/106 1.5d version)

    350ml would be fine as long as the tank is the highest part of the coolant system.

    The height part is far more important than the capacity.

    as martin says height is the most important thing not size and the top small hose must enter above the water level in tank or it will not allow air to escape from rad very easily and must be connected to the radiator --you can,t connect it to the heater hoses --
    so fitting on n/s will mean long hoses and will need to have top of tank above top of rad for best operation.
    I would move the ecu to inside the car - simple enough to cut open loom and separate ecu wiring from oil switch and alternator and then just put it in glove box and make small loom for those elec wires --should be no need to cut any wires
    also will give you the chance to solder the large crimps in the loom at back of engine --they are very prone to bad connections as they get old .even though they may look OK. and mus be at least 14 years+ old now .
