    So the about a week ago now I cleaned my cooling system with a flush, and upon refilling and a small drive I noticed I was losing fluid, got home had a small crack in side of radiator plastic (drivers side) so I pulled it all out and replaced it. I had been having troubles with keeping water so I ended up replacing the lot, radiator, hoses, water pump and thermostat, filled it up with coolant and bleed the system, all seemed to be fine until earlier today.
    It seemed as if my ac cut out and then it started to overheat, ac come back on and it went back down, but after a few moments started to go back up again.
    Just wondering if anyone has any idea what could be causing this
