Celica Overheating

[MGZ930]

Hello,

I've recently bought a Celica and it's the T sport. It had a leakage in the radiator that solved the overheating for a while. After a month now the car is back to overheating and won't cool down. when I put the AC on it'll only blow cold air and no hot air will come out. It's something bothering me a lot and I am unsure what the problem seems to be. I'm not much of a Car expert but anyone experienced this same issue and can lead me to the solution to this problem. My doubts are that its the head gasket but I hope it's not that.

Kind regards,

Michael

When the leaky radiator was sorted, was the cooling system filled correctly?  Does the Celica's cooling system have to be bled when being refilled?

Have you checked the thermostat is working OK?

Can't answer about the air con.
