First off I will apologize for my long post but I’m having some issues that I need assistance with. I have had the headgasket looked at and tested all came back perfect.

Firstly I did replace the radiator it was falling apart. But more issues came up afterwards, my fans weren’t coming on so I replaced the engine coolant temp sensor and replaced my radiator fan motor because it was bad. They worked! But then I noticed that after putting coolant in, that it was overfilling my reservoir. I thought it would change as I drove it since there was no coolant in the system until I put it in. But here recently it has tried to overheat and it’s actually pushing the excess from the overfilled radiator out everywhere. So I took it off emptied it to a normal level and it did great, but I still find myself having to put coolant in the radiator every 2 weeks which concerns me. There’s no coolant loss (except the reservoir incident) so my next step is to “burp” the system and hope that maybe it had air in it that had no way to escape? I don’t know I need some ideas
