I heard that your aluminum radiator does't like chemicals. If I were you I'd pull the radiator to flush. I'ts not that hard, plus you won't be spreading that s**t to the rest of the cooling system.

the radiator has had it, i got a new one coming tomorrow! ive flushed the rest of the system with water (pressure hose) but no sure if that good enough?

Which car of yours are we talking about and how long have you had it? If the PO was having cooling problems I'd also replace the radiator cap & thermostat. If you're getting coolant level messages, you might want to replace the level sensor while you're at it.

Did you drain the block? Did you flush the Heater Core?

Yeah I remember now.

In draining the block, there are 2 (I think) drain plugs.

Since you did overheat I would definately recommed replacing the radiator cap and probably the thermostat and you should be good to go.

The Bentley doesn't seem to cover the 520i? Anyway it says the drain plug is towards the rear of the block, on the exhaust side of the engine, below cylinder #6
