Hi, recently my car overheated and their was a loud grinding sound from the engine. We have now flushed out the system, found one hose completely blocked and flushed the radiator. Prior to all this the heater was constantly blowing hot, once we flushed the sytem for a brief moment there was hot and cold air, but now I'm back to only having hot air again.

I have watched your video on how to fit a new cooling valve but could you clarify something.....can I change this without having to drain the whole coolant system again?

Thank you for the great vids and for your help.

no need to drain the cooling system,just make sure engine is cold.
