Radiator leak

I went to go to the garage to drive my truck today and noticed a small stain on the ground. When I inspected the front grille, there was a little liquid and some rust formed behind it. It’s bright green in color so I’m assuming it’s the radiator? It was changed two years ago and wondering if anyone can spot where it’s possibly leaking from. Thank you fam!

To be sure loan a cooling system pressure tester from your local auto parts store .

How much coolant have you needed to add every day?

 

I just noticed it today but the overflow tank is slightly below full and the main tank when removing the cap shows full. I will definitely try and rent the coolant pressure tester. Now that I look at it, the overflow tank does have another hose that points towards the ground and could have just overflowed out. I was idling it outside for 20 minutes trying to diagnose the AC, maybe that could be a reason?

 

Got to really inspect radiator on that driver side. Top to bottom
Typically, the aluminum crimping to the plastic ‘cap’ is a weak point. Check front and back of aluminum portion of rad for wetness
IF rad shows full(when cap removed)
Points to an upper leak on rad
If the radiator
As Bivouac stated, pressure tester will show if bad radiator if no visible damage/leaks found

please tell me you have never seen coolant reservoir fill to top and burp out liquid

 

Surprisingly I have never seen it but it seems like that is the culprit after inspecting the radiator. I will definitely rent the tool to confirm. Thank you so much for sharing your knowledge to this noob!
