    If your P-gasket hasn't been replaced before, you'll probably find it's perished... Looking from the nearside wing down behind the alternator you may see something like this...

    Firstly dump the coolant from the engine, then remove all coolant hoses and the top intercooler hose from the top of the engine and thermostat housing, this gives you plenty of space to get at the rest of the job

    Before removing the serpentine belt, try and crack the bolts holding the waterpump and steering pump pulleys


    [​IMG]

    I couldn't get the steering pump bolts to crack without the belt slipping, so I used a strap wrench to hold the pulley while I cracked the bolts.


    [​IMG]


    Completely remove the pulleys and you can now access all bolts holding the waterpump on, then remove waterpump


    [​IMG]


    Remove the four bolts marked with arrows and the power steering pump will be liberated

    Pull the pump out of the way, and you can then turn your attention to the last three studs holding the waterpump housing to the engine.
    A – is a nut
    B – is a bolt
    C – is a nut, attached to a bolt which you'll need to hold from underneath the alternator


    [​IMG]


    Once these are undone you can pull the entire lot forwards to access the p-gasket, be careful not to strain the cables to the alternator

    Clean off the old gasket then fit the new one with a smear of grease to hold it in place, you may wish to use gasket sealant – but I hate the stuff so I didn't!


    [​IMG]


    Slide the waterpump housing back onto the studs and quickly insert one of the long waterpump bolts to hold the gasket in place
    Refit the bolts and nuts to the housing and then refit the steering pump and waterpump (with new gasket)

    Refit belt and all hoses and refill the coolant and t'jobs a fish!

    Other Advice from the original thread:

    > Buy a metal type gasket not a paper one (I got mine from paddocks)
    > You can actually leave the water pump attached - just remove the long bolts at the bottom of the pump and the rest can stay together.
