Car: 1996 SL2 with 163,000mi

Does anyone have any advise on an anti-freeze leak that is on the driver's side? I have replaced the top radiator hose already and the reservoir cap. It make about five puddles when parked. They are along the perimeter of the driver's side of engine bay and make an 'L' going towards the front center directly under the fan. There are no puddles under the passenger side of the engine bay. If it is a cracked radiator, than has anyone replaced one? What's the cost and the difficulty of it?

 

side tanks are plastic and usually crack by upper mount on drivers side -- do not neglect and do not let it overheat

put in a QUALITY replacement or you will end up doing it again in 2 years

 

Should they have them at a store like Autozone? Are they difficult to replace? Thanks for the help.
