I have smelly smell coming out of the heater in the car. I think radiator coolant is not well bleed. How can I bleed the radiator?

Couldn't be simpler. Take the cap off the expansion tank on the side of the radiator and run the engine with the bonnet up for about 10 minutes. Let it cool and top up the coolant if you need too. If it doen't work try it another couple of times and if it still doesn't work looks like a different problem I'm afarid...
