Radiator Leak

[Rednel]

I am attaching a photo here. I noticed I was leaking some cooling fluid under the car and the plastic where the fluid is here has a small hairline crack in it that is weeping this fluid when it is under pressure. I have not lost that much fluid at the expansion bottle but its definitely an issue needing fixed.

Does anyone know if this is a complete new radiator that is required to fix this?

Thanks

Simple answer
YES, and please do not go and buy the cheapest out there as they are junk
May as well replace thermostat ( with MOPAR ONLY ) and hoses , plus flush and new HOAT coolant

Drat! I thought that might be the case. My KJ has been costing me some $$ lately.

Thanks for your help and advice.
