You know about the PHH, but do you know about the EBB (Easily Broken Barb)? Yep that silly little plastic barb right on top of your radiator that'll snap off when you up in your engine working on it. Well, don't replace your expensive radiator, do this instead...
Order a new barb. This is the one I used: ttps://www.amazon.com/gp/product/B07DXR725M/ref=ppx_yo_dt_b_asin_title_o04_s00?ie=UTF8&psc=1
You can add the little washer it comes with to your scrap hardware coffee can, we won't be using it.
Here is the situation at hand...
Now take a flush cut saw and cut off all the topography like this...
There is still some left due to the curvature of the radiator top...
So take some sandpaper and sand it flush...
Now drill the hole larger. You were going to replace the whole radiator anyway, right? Got nothing to loose. I can't recall, I think i used a 13/32 bit for this. When in doubt, start smaller and work up until hole is big enough for the next step.
