Yeah what he said sorry i didnt explain as well as i should of. Basically tqake both hoses off that go to the heaer matrix on the bulk head put your hose pipe on one and put some rages near the other to help clear the water, turn hose on and loads of gunk will come out. and to bleed the car let it get up to temp with the rad cap off and fans on full inside. Keep squeezing the pipes until no air bubble come out. Take it work a short drive to shake any air around the system, let it cool down, take the rad cap off start it up again and check for air bubble and top up as required.
