rule of thumb on cars after 1970. heat rises(water coming out top of engine is hot). so disconnect the top and bottom hose from the engine and let the coolant run out (either into a container or into the gutter) the put a garden hose on full up to the top (not the cap) of the radiator and run through the whole thing for about two minutes. then put on the bottom and repeat. then reconnect the bottom hose and run through the top (not the cap) of the radiator so that water passes through the radiator and the block (engine) for about 10 minutes, or about 3 minutes after the engine reaches running temperature. when done with a quality radiator flush product the radiator clean enough for a coolant change.
how do I bleed water system on the 806 peugeot
Sounds very much like the cylinder head gasket is leaking allowing compression into the water system. with the radiator cap off bulles will be seen in the water when revving the engine. A garage workshop normally use a sniffer to check for this, not too expensive to have checked.
You don't bleed the water pump, you bleed the cooling system. Just jack up the front of the car or park it on an uphill incline and remove the radiator cap. Start the engine and let it run until no more air bubbles are escaping from the radiator. If it has bleeder valves use them to bleed the system. The water pump will bleed right along with the rest of the system.

Most likely is that a gasket or seal has blown, or a crack in the engine block is letting water in from the cooling system.
Find the highest heater hose joint on the dash under the hood, turn the heater water control on, run the car so the water is circulating and loosen the clamp and loosen the joint at the hose to let the air out. When only coolant flows tighten the connection and your done.
on hot water heat with a boiler you should pressurize the system then open the bleeders
To bleed the cooling system on a 1996 Olds Cutlass, locate the bleed valve, which is on the front of the engine above the water pump. After making sure the cooling system is not under pressure, open the valve by turning it counterclockwise. Fill the radiator with coolant until no air comes out the bleed valve, and a stream of coolant begins to flow from there instead. Tighten the valve and close the system to finish the job.
