radiator overheating, please advice

[LRDHSE2003]

took a 600 mile trip this weekend. checked fluids before take off everything looked good. on arriving back home radiator arrow started to gradually work its way to the red area. i turned off ac immediately. when i parked the red light turned on and the arrow fell from red to the bottom and stayed on like that when i restarted the engine. noticed fluid leakage aroung the cap area. any suggestions or comments, i am totally clueless.

Sounds like the resevoir has cracked. If it is black buy a new one. The white ones are the better version and newer.
