Default Radiator Removal Impossible to Reach Bolt?

Anyone replace their radiator on a 2013-2017 LS? I can't get these bottom bolts



, that hold the radiator to the condenser, out either from above or below. My flexible socket nor my offset 10mm wrench can get on the bolts right. The pics make it look there there's plenty of space but that frame is in the way of making it easy.

From the looks of the dents that must be the condenser, the rad is behind it.

Yes, that's correct. The view is in front of the condenser and the radiator is directly behind it, held together by these and two more bolts above. I'm hoping someone has been able to remove these without taking off the entire bumper. There is a video on Youtube but it's an '07 and the front grille can be removed which is much easier than removing the entire bumper.

1/4" drive ratchet and socket won't fit? Grind down the socket if necessary. What about a ratcheting wrench.

Have you removed the fans/ shroud and the upper rad support yet?

My ¼" ratchet didn't fit but I appreciate your suggestions. Just ordered a bunch more tools on Amazon. I think a bigger offset wrench might do it.

If you have removed the upper rad support you can lift up on and shift the radiator/condensor assembly to get clearance. Remove upper hose as needed.

The upper radiator support is off. I left the fans on and will slide that out together with the radiator once it's free.

This started with just replacing a leaking thermostat but it's evolved into doing the water pump, drive belt, belt tensioner and pulleys, and radiator since the Denso part wasn't much. I have just over 200k on my 2014 LS.
