Hi everyone,

I wanted to ask your input, I do not know anything about cars.

My car is Toyota Corolla GLI Automatic. I had to replace my stock radiator with 2-rows radiator.

After then, I am starting to hear extensive vibration and rattle noise when the AC is turned on. I do not experience this before, just like right after my radiator was replaced. When I turned off the AC, the noise/vibration will go off.

Is there any connection when I replaced it with 2-rows radiator? Should I directly go to a mechanic or a Car-aircon specialist?
