1. Pull the bottom hose off the radiator

2. Will say on the bottle

3. Any coolant, nothing special

4. Mix the coolant with the water first
Engine switched off, make sure bleed screw is out, pour coolant into
bottle until it come's out of the bleed screw hole.

Once this is done, start engine and coolant will fall to the level poured
into engine, top up and let it settle (getting rid of any air), once settled
put the bleed screw in and you may have to rev the engine for the
water to come out of the filler and drop to the level on the side of the
bottle on the side of the rad.

Hope that help's
