i have an idea as to what i may need to do, but i will ask the expert panel on here if my "cheat" will work.
i recently replaced my radiator as it developed a good sized hole in it. when i was at the junk yard, i accidentally broke off the barb part that the overflow connects to. thinking i could make it work without trucking all the way back to the yard two hours away, i took an old tire stem with the valve removed and cut it down to size and pounded it in. i also applied some sealant to keep it from leaking. radiator seems to be fine. but i notice when i go for a hot restart, the engine chugs a bit until i give it gas. i also notice that the temperature gauge falls back down to cold even though its full and burped of air. my suspicion is that the sealant is not holding pressure, and the chugging is caused by the ect thinking its cold when it actually is hot.
could i remove the sealant and replace it with epoxy to help the radiator hold pressure? or do i need to bite the bullet and get a new radiator? also, (and i know this has been a hot topic on here) will a 13lb radiator cap really cause air to leak into the system? i have seen many people comment that and that a 16lb is the right one to use.
