how do i bleed the water system on my 1998 vauxhall astra the radiator is warm on the top and the rad is cold on the bottom so i assume the system is filled with air

providing the radiator is not blocked u can bleed it using the heater hoses attached to the bulk head find the one that returns water to the engine and undo the hose clip just enough for the air to escape run the engine until there is no more air in the system keep an eye on the temp and the water level
