2014 E350 4-Matic Coolant Leak

Hello all,

This morning, I went to go start my car this morning and I saw a pool of coolant on the ground. I decided to go under and find the source of the leak and I took an image of what I saw.

This is from the driver’s side of the radiator near the petcock to drain the coolant.

Do I need a new radiator? I couldn’t find any leaks coming from the hoses anywhere else.

I have about 90k mi on the car so I wouldn’t be surprised if the radiator was starting to go.

Thank you for any help!

you probably need a radiator, the water pump gasket starts to blow out too so check the weep hole to see if its losing coolant.

RockAuto has the excellent Denso and CSF ones which I've used extensively specifically with W212's
