Hello,

Yesterday i travelled on motorway for approximately 400km and the next day i checked the coolant level it was full but my radiator cap was broken from inside. as i lifted it out the spring was resting in the upper tank which i took it out with a tweezer, but the little plastic thing in the inside of the cap is still inside the cap. what should i do?
I have replaced the cap with a new one. Can i drive my car to the mechanic with that small part of the previous radiator cap in my tank or not?
What should I do? Need help.

You should be able to remove the seal part of the old cap, I would not drive it because the system could overheat. Use a pair of needle nose pliers and a small flat blade screwdriver should do the trick. Let us know what happens and please upload pictures or videos of the problem so we can see what's going on.

Okay, then it sounds like you can just get a new cap, can you take an image of where the radiator cap goes?
