How can i remove all air pockets from radiator cooling system on my 406 coupe v6?

Question

I have recently changed the coolant in my peugeot 406 after series of overheating issues due to the radiator cap being damaged.I done the mixture 50/50 as adviced but the temperature of the car seems to be between 90 and 110 degrees cent. which i think is still quite high and since then the heating in the car seems to be cool rather than warm.after reading various related answers on here.i believe its got something to do with air trapped in the cooling system and apparently need to bleed it somehow.anyone knows how best to do this.Also,after allowing the car cool off for bout hour and half.i opened up the radiator cap and the coolant came pouring out.any ideas or suggestions

Answer 1

Hi mate, take a look at your other question on this one, I've given you a thing on how to bleed the system, I did it when I changed my radiator and even in extreme traffic doesn't pass 90oC, normal operating temp is 75-80oC.

Answer 3

Try parking it on very steep hill with the radiator pointing up hill. Then remove the radiator cap (cold) and warm up the engine with the inside car heater on full hot. Hopefully when your engine is hot enough and it's thermostat opens fully, all the trapped air will be burped out of the radiator mouth. Top off the coolant and replace the radiator cap.

Answer 4

Have the heater on so the air wont trap there you can let it idle with cap off till air escapes some time this wont work > So heat up shut of it will perg it self if you put the correct cap back on>>Have anti freeze in the over flow tank and keep checking it>

Open the water filler, start the engine and leave the heater on full heat (no a/c). Then when is it warm, squeeze all of the water hoses. Have someone rev it to get the waterpump pumping quicker and it will be okay.
