Hi my site name is Thoroughbred 323ic, real name Robin. I am a new BMW owner needless to say by my site name you have an idea of what BMW I'm driving; 323i convertible, 1999. I purchased car with 113,00 miles on it and the check engine light was on. Ran the codes and minor repairs (O2 sensors) corrected that problem. I got home last night and radiator has sprung a leak, I am in the process of removing it to replace it but I am having trouble trying to figure how the two plastic hold downs on the top two corners release, each has an arrow on the top pointing towards the front of the car (away from the engine). When yoy push it in that direction it lifts up (some) but does not come out so the radiator is free, so I'm stuck and do not want to break those fittings, is there someone on the site that can help me out. Thanks in advance.
