And this is where things turn dark.
I put the new radiator in and was having a helluva time fitting the existing small hoses over the new barbed fittings. The units went into place fine but the lower coolant hose didn't have a staisfying snap into place like before.
I got everything installed and filled the overflow reservoir with coolant. I decided not to start the engine and inspect for weeping fluid. After about ten minutes the new coolant began showering the front skid plate like a sounds of nature video.
I didn't want to tear the whole thing apart again so I removed the skid plate and the rest of the air box to watch in horror as coolant steadily streamed out of the lower coolant hose.
I got the pump back out and removed the rest of the coolant from the radiator. I then went over to the radiator box and cross referenced it with my confirmation email of the items purchased. I had bought the right radiator but received a radiator for an F150 V8 truck. Not a Raptor. These things are built like tanks with a Frankenstein of commercial duty Ford parts to handle the extreme temps and abuse that they were designed for and F150 parts everywhere else.
I was happy that the leak wasn't because of how I put it back together and pissed at the same time that I had spent all this time putting in the wrong radiator.
I spent the next 5 hours uninstalling the new one and reinstalling the old one.
