I ordered a new radiator and it fit like a glove. The issue just turned out that the old unit didnt fit. All in all, the procedure was pretty easy. The biggest hassle was a cold garage in 0deg Chicago temps! Here are the steps to replace the radiator.
1. Remove belly pan. Most of my 10mm were rusted and gone so I couldnt tell you how many are there but there are videos on the internet for this. Heres a reference video : https://d2n97g4vasjwsk.cloudfront.net/2 ... 20480p.mp4
2. Drain coolant. On the bottom end tank near the lower radiator hose connection, there is a drain plug with a plastic phillips screw. Unscrew that and the coolant will come out of that hole. Heres a video for reference: https://d2n97g4vasjwsk.cloudfront.net/2 ... 20480p.mp4
3. Once all drained (pull off the radiator cap also), disconnect the lower and upper radiator hoses.
4. Remove trans cooler lines (I previously installed a dedicated trans cooler to prevent getting the strawberry milkshake so I skipped this step). There are two lines at the bottom of the radiator.. take them off and plug them up.
5. Remove snorkel and airbox. Heres a video from the internet : https://d2n97g4vasjwsk.cloudfront.net/2 ... 20480p.mp4
6. Remove fan shroud. This part is two pieces. On the bottom half, there are two clips on each side (red). Squeeze them and pop them out towards the engine. The lower shroud can be now removed from the bottom of the car. The upper shroud is held onto the radiator by two screws at the top (yellow) and slides into 2 grooves at the bottom (green). This can be lifted out of the car from the top. https://imgur.com/AbKOAMP
7. The radiator is the only thing left, unlock the clips holding the top mounting points by spinning them. When they are lined up, pull them up and out. The radiator is completely free now. Tilt the top back towards the engine and pull it up and out of the car. In my case, it was hard to pull up. I went under the car and pried it out of the bottom mounting holes to make it easier to remove.
8. Pull the upper and lower rubber bushings off the old radiator and use them for the new one. Follow this in reverse order and youre all done. Add coolant, burp and go.
