Anyone ever successfully remove inverter radiator?

Good afternoon! I just joined this forum because everyone has a ton of insightful and useful information and I could use some help.

I am looking for advice from anyone who has successfully removed the gen 3 inverter radiator/cooler. A rock got into my inverter radiator through the front grill and it’s not really repairable. I’d like to attempt replacing it at home to save myself several hundred dollars. Also doesn’t help that this happened on my birthday -.- so I’m trying to make the best of a bad situation!

Is it a difficult job, and can I access what I need from the top? Does the entire radiator need to be removed? Any advice would be greatly appreciated

Thanks
