for the AST removal? They say they are meant for unused water pump, engine, underhood uses but they seem awfully flimsy.

Please let me know - thanks!

 

nobody????

 

They may have changed the design, but I used some 3/8" ones when I first removed my AST. They worked fine for a while, but both of them popped after a few months. It's ugly, but I think a short section of hose with a bolt in the end of it and hose clamps on both sides is a much more robust way to plug the lines. I am sure there is something better out there, but the HELP! caps just aren't beefy enough.

Thanks Max! That's what I figured. I may have to search for something better. The bolt/rig came to mind as I searched four stores for the 1/2" caps and finally found 'em. You said 3/8's inch? Seems like the lower radiator and coolant neck are 1/2". Tried 3/8's on the upper and it wasn't going to work...
