It's the radiator fan, its sticking. Had it out and took it off the bracket, gave it a quick spray of grease, and took it out for a spin to see if it had helped. But now its just came back on as I'm parked up. The fan itself felt like not really tight on the motor, and is throwing the whole thing off balance, causing the vibrating of the fan and motor, and the scraping of the blades.
Is it new fan time?
Any ideas?
Ta,
