    I want to change the glow plugs. 1- Do I need to disconnect the battery? 2- Does the engine need to be hot/warm to ease the thread? 3- Is it wise to use a penetrating oil to release the thread?
    Is it necessary to also replace the control unit?
    Only just having issues starting car in very cold weather.
    Please advise.
    Thanks

    On my car when replacing glow plugs I removed the terminal from the battery, the replacement was made not on a hot but on a warm engine, I used penetrating oil but I do not know whether it was correct or not.
