What if it Snows?

Unless that one insert starts spinning...

 

That plastic is really tough, I think you'll make it fine without touching it. On mine I had to take a soldering iron and melt the plastic from a portion in front of the metal insert so I could pry it off leaving the bolt in.

 

I just had to remove it to get to the fan clutch. I'm sure I looked at the insert once the tank was removed and decided that replacing the radiator was the only real remedy.

 

Another possibility, is that, I accomplished what I had set out to do and figured, meh; it still works. Seriously, I can't remember exactly what I was thinking (2 years ago.)

 

It was an easy job on mine 1 to 2 hrs including beer breaks

 

Remove and replace on the coolant tank is fairly easy. Big problem is finding a way to catch the coolant.
A siphon hose and a few empty coolant jugs could work. I think you could do the job. Think about the OM and how you saved them some cash. They’ll be bragging on it.
