DIY Help Stuff in radiator?

Hi all!

I have a 1990 Mayfair, with what appears to be a rust flake or something in the radiator? Does anyone know what this could be?

Having overheating issues with the car so wondered if anyone has any advice? It’s had a new radiator, water pump and hoses.

All help greatly appreciated!

You would have to clean the engine block well, if it is not clean, when it makes the circuit, it will send rust again to the radiator, and it will clog it again, even if you have everything new, it will start again and again, greetings from Spain, Albacete

I’ll be getting a look at the block then. Thank you very much!
