My friend who lives about 400 miles away from me is stating that her car (2000 Chevy Cavalier) doesn't have a radiator cap. I've only owned cars from 94 and before, but I can't believe that there isn't a cap. How do you check the fluid lvls and do you just use the overflow to add or is she insane? I told her that it's gotta be on the top of the radiator but she says that it's not there. Is there a cover or something she needs to remove, or does it really not have a cap?

Thanks in advance.

The pressure cap is located on the fluid reservoir not on the radiator itself. This is a common practice on newer vehicles so a radiator cap is generally a thing of the past. Now they are called pressure caps and are located on the reservoir.

So then how would you check the fluid lvl in the radiator? Seems like newer cars are almost impossible to maintain yourself.
