Need support. Just found out my radiator is leaking

Wish I could see under the rad without removing it

looks like residual water, give it a couple days to dry out

Doesn't look a lot like coolant to me, but you could pressure test the system to see if it's actually losing pressure.

The drip on the cardboard looks like transmission fluid, or maybe weak Dexcool.

There was some trans fluid. Not seeing any anymore. I’ll keep an eye on the level I suppose tho. As well as my coolant reservoir. I think I should take it into the shop and have my guy double over my work

I was gonna try using an air compressor to blow the pan underneath the radiator. Whatever that metal thing is. That’s where it is coming from. Like the first photos I showed yall when I found the leak.

Definitely coolant.

Definitely coolant.

probably still residual, like I said with those bumper brackets coolant can pool up in places you can't see or reach

Like Wes said, when you pull the lower hose off the old coolant goes everywhere and can drip for awhile afterwards. Wait a few days and then try the cardboard under there. If you hosed it off in that area it will be water mixed with coolant dripping otherwise it can be straight coolant. I never used any cardboard to check because I knew things would probably drip a few drops for awhile. That stuff seems to go everywhere and there’s lots of places for it to hide and slowly drip until it’s gone.

I got under and took of the shield and it looks like it’s leaking in the same spots.
This isn’t a current image, this is before I changed radiators. A couple days ago But it’s the same area kinda, there’s little drops forming on the harness there. And even
After I lightly sprayed down the area with a wide nozzle.

It is an OSC radiator ‍ hopefully not a pinhole leak …
