    Question Header tank

    Can anybody tell me if the header tanks on all Astra G's are the same or is the Z20LET header tank different? Also best place to get one from? How much brand new from VX?

    Providing u get a one from an Astra G with the sensor in - it will fit

    (early 98-00 1.6 8v tanks are different [only 1 small spout on top] but just had to mention this in case sum1 reads this in future)

    Zafira A use a different shape tank so must be for an Astra.

    £20 or so will get u a brand new tank from Vauxhall under part number 9117438

    Question Header tank

    What is MFD? So if i'm on the lookout for a 2nd hand header tank, does it HAVE to come from another Z20LET or can i use any model that has a sensor in it? And in that case how do i know which models had a sensor in the tank???? There are a few on ebay for around £8 but want to make sure i'm buying the right thing. Also what will happen if i fit a tank without the sensor?

    if youve got a gsi then you will have a mfd (multi function display),its the digital read out in the middle of your center console that tells you your average mpg,speed etc. the reason you need the one with the sensor is if your coolent level gets low this sensor in question realises that and send you a message on your mfd that says coolent level warning
    God bless turbos!!!!
