No tools mate, Go to any auto store and get yourself a 355ml bottle of LUCAS Power Steering Stop Leak, about $12, then just top up your P/S Pump reservoir, do not over fill, it has a dip stick attached to the lid which gives you the correct level, if it has been leaking for a while, you will find that you may get half the bottle in which is great, otherwise, you can try to remove some of the existing fluid by removing a hose, or scooping it out with something.... as it leaks, you will find it will need to be topped up and this gives you the oportunity to get some more in. It is known to be a little hard on worn out Pumps due to it's viscosity, but if your pump seems fine, then it should be OK.....
It's a white plastic bottle with a little blue cap, easy to find.
