Coolant change - radiator now foaming!

[rossyl]

Hi

I put some Wynn's Rad Flush in with the old coolant.
Ran the engine then drained it.

I then stuck a hose in the rad and ran it till Clearwater was coming out of the rad.

The car was parked on a sloped road. The nose down the boot higher.

I then put in the new Anti Freeze. I was only able to get in about 4 litres. I know it should take 6.

I ran the engine with the radiator cap off heater on full. Foam then started appearing out of the radiator cap.

I figured this was just air escaping. But I couldn't get more antifreeze into the system.

I then moved the car around, parked it with the nose higher. Ran it again with the radiator cap off with heat on full. Foam still appearing.

I took it for a drive, temperature was fine. Now just waiting for it to cool down. Again it's parked on a sloped road with its nose higher.

Have I just got a massive air lock?
Or did I not drain out all of the rad flush?
Or is it all fine?

Thanks

I suggest that you park on a flat road next time.

I would keep checking the temperature and the levels. If the temperature stays as normal and the level does not drop then its okay. If not its just a case of putting it on a level area and making sure that you drain the system of all the water and top up after with good mix.
