Might be able to tap in some pipe threads and screw a 1/4 " nipple in there, pretty easily

 

X2 easiest and cleanest way in my opinion. Made it through the PA winter with no issues I noticed no difference with all the cold we have had.

 

Putting two bolts in the hose side what do you do about the throttle body side? Leave them open or plug those as well? What's the best size bolts to use to plug the hoses? I just noticed my TB is seeping

 

Left the TB side wide open, the only thing circulating through that thing now is air. The bolts I found in my junk pile, they are about an inch long and they fit tight inside the hose before the clamp is applied. I think that's all that matters. This method hasn't leaked a single drop of anti-freeze.

 

I'm glad you said that. I used bolts and as I read the thread I was wondering WTH have I done?!
