Hi I just bought my c3 1 month ago and last week it started overheating, so I checked My levels and they were fine. So I checked the thromostat and the spring didn't go all the way out so I bought a new one and flushed the systems cause I didn't know what was in there previously, and then after that I ran fine but I noticed the thermostat housing leaked it was cracked so a little stream of water came out, I changed that one as well and welp its still overheating and I need to refill it again now, the lid of the tank is good doesn't leak air or anything, qnd when I flushed the system there wasn't any blocked anything, the pressure on the rubber pipes runing from the top of the radiator intro the thermostat and intro it agian are really filled and expanding a bit. The fan is working as well.
But yeah the overheating doesn't stop
Does anyone have any ideas?

Hi

You are unlucky. The test drive should have shown up cooling problems or at least - reported cooling problems.

With such an old engine, maybe 2002-2005, maybe 2006, but still old, I would do a quick head gasket check using one of those I linked to.

You have done all the other basics, so that leaves a faulty heater signal where it says it overheating and it isn't (you never said how you knew it was overheating) or the head gasket, which is not uncommon on the petrol engines of that era.
