Look at the radiator, at the bottom will be a pipe that runs from the rad and across the front of the engine block. Bit of fiddling with some mole grips to get the spring clip off and that's it, iirc it's the lowest part of the coolant system so ideal to drain it.

There's three bleed screws. One on the heater matrix pipes that go into the bulkhead, just to the right of the master cylinder. One is on top of the thermostat housing on the engine block. Follow the big pipe from the top right of the rad to the engine and you'll see a brass allen headed bolt sitting on top of the housing. Finally there is a screw on top of the rad where the big pipe joins the top of the rad

As for a header tank, take the rad cap off. Cut the bottom of a coke bottle off and turn the bottle upside down, then wrap insulation tape over the neck of the bottle until it fits snugly into the top of the rad where you took the cap off. Bleeds by gravity so you need to keep the header tank topped up, helps if you park the car facing uphill to keep the water level in the header tank higher than the highest bleed screw, the one on the heater matrix/

Job jobbed.

nice one cheers mate so do i have to adjust these bleed screws? And the pipe on radiator is the one just by alternator? Unfortunately by sounds of things some one has changed the clip to a jubilee one i had ago @ it earlier with no luck!

Given the lack of space down there i'd prefer having a jubilee clip!

I always use that pipe because you can blast water back through the rad and back flush it as opposed to just draining it.

Its not there on all aftermarket rads + its easier to whip a pipe off

Maybe I just never bothered looking just always pulled the lower pipe off the rad

You'll know if you're drained it right, as you'll have a big wet shiny driveway

That's correct, to refill you'll need to make yourself up a header tank so the reservoir is above all the other points in the system, then fill it up with all the bleed screws open (not removed if you have the butterfly type) until the water comes out of each, then close the valves.

I then tend to run the engine for a bit (best done with a cold engine so you don't burn your hands when the coolant instantly heats up) - this'll start the water pump and will displace any air bubbles around the system. Then I go about the bleed screws one by one and bleed them like you would any radiator, until the bubbling stops and you just get a steady stream of water out.

Header tank, if done professionally, looks something like this:



Edit: And the matrix pipe bleed screw is the bit marked in blue here:

No you won't have to remove the heat shield, that'll be fine.

Without a header tank only the two you mention will bleed properly, if the matrix one isn't p*ssing water then it's still got air in it, hence needing a header tank to make sure that happens. It's the matrix one that's the highest, so it's important to get that one bled.
