i'm new to this site also but not to jeeps, i near the eldon/lake area. my daily driver is a red zj with 225,000 and counting and my toy is an 80 cj5. 4.0 in the zj and a 258 still sits in the cj5.
also if the bottom radiator hose is not fully sealed on the water pump coolant will run down it and it will look like the radiator is leaking. now for the bars leak, please take your jeep somewhere and have your coolant sys flushed.
