Hi
So last week my MGF overheated on a fast moving road. This happened after driving for a bit, stopped at services, then carried on with my journey when the temp gauge shot up and it started boiling over.
RAC man come out and topped up the coolant, and it all seemed fine. He couldn't spot any leaks etc. and the car seemed to be running ok. I was able to carry on driving without it overheating again.
I suspected the expansion tank cap was faulty so I bought a new one.
Had to go out this morning, and I was travelling at about 50mph, and the engine management light started flashing. It stopped when I slowed down. Is this likely to be connected to the overheating?
Also after I got back I wanted to check the coolant level. After letting the car cool down (about 3 hours), when I took the cap off the expansion tank it seemed like it was pressurised. I'd never really known that before on a cold engine.
