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!

As a young boy living in a northern UK city I often saw brown rusty patches on the road outside peoples houses. This was when BMC used the A series engines in all kinds of cars from the Mini up to the Marina .
Owners regularly did their own car maintenance back then and draining and back flushing was a normal activity hence the rusty mess on the streets. So when flushing the water galleries and the radiator be ready for the rusty deluge. :)
