    water pump question

    hi all...had a cambelt kit fitted about 6month ago(belt and all other parts) and now ive got a noise from the cambelt area which i think might be the water pump.ive heard somthing about new belts causing water pump wear due to them been new and a bit tighter.

    1st question.the noise seems to be in time with the cambelt and goes somthing like this......brrrr....brrrrr......brrrr....brrrr..... brrrrr
    if u get me. does this sound like the water pump

    2nd question. how hard is it to fit.ive done a cambelt before but never done a water pump,do i need any special tools

    3rd qeustion.will this fit my car. http://cgi.ebay.co.uk/WATER-PUMP-VAU...QQcmdZViewItem

    car is a y plate 2001 mk4 astra cabby Z18XE

    THANKS ALL

    could well be your water pump mine recent went.

    the noise i got was a sort of scrapy/bearing wiring noise (very difficult to discribe)

    as for fitting the new water pump its not that difficult.

    the tools you will need are
    axel stand
    trolly jack
    a camlocking tool
    a set of inverted torx sockets
    standard socket set
    screw drivers
    and a torque wrench

    a haynes manual may also be of use.

    to make the job easyier tho the haynes manual states that the cam pullys need to be reomved in order to remove the rear camblt cover so that the water pump can be removed.
    this is not nessary if you wedge a large screw driver behind the rear cover you will be able to remove/replace the water pump bolts but before you remove the water pump draw an alignment mark on the rear cover and the old water pump as the alingment mark on the block is not visable with the rear cambelt cover on then transfer the alingment mark to the new water pump and bobs your uncle no need to remove the cam pullys.

    as for a new water pump try www.autovaux.co.uk i got mine for £20ish

    i would also recomend getting a new cambelt although the old one can be refitted just make sure you put it back on the same way round.

    yeah i was a bit nervious myself as i have never attempted any thing like this before. Normally an oil change was about as technical as i got but i couldn't afford the £500 that vauxhall wanted for a full service and replace the water pump so i did it myself at the cost of around £100 in parts.
    well with the help of a freind but even so was a quite a nervious moment when i turned the key to see if the engine would start made even more nerve rackking by the fact that i replaced the fuel filter so had to wait for the fuel pump to pull the fuel through the system.

    needless to say the car has run like a dream since

    i used a friend impact gun.

    was on and off in seconds.

    then torqued it up the last little bit with a torgue wrench.

    no need to lock the crankpully just make sure it is correcly aligned before refitting the timing belt. there are alignment marks on both the sprocket and the block

    there are infact two pullys the large one which the althernator belt runs around which is visable without reomving anything on the car and then the inner one which is behind the lower cambelt cover which drives the timming belt.

    remove the large pully
    the engine shouldn't move it didn't with me anyway.
    once removed remove the lower cambelt cover
    then the alignment of the engine needs to take place and this is when the cams are locked in place.
    there isn't anything holding the crank in place but it shouldn't move but if on the off change is does move then realign it before refitting the timing belt once the water pump has be refitted.

    once the timing belt is back on reffit the lower cambelt cover
    then the large crank pully
    when refitting the large crank pully then timming belt will be back in place therefore everything will move togerther if the crank does move when refitted
