Changed oil and filter on my 92 Olds yesterday, and during my underneath inspection I found that the radiator drain petcock was leaking. Went to tighten it up, and it just started leaking more. It would not tighten because the stem was broke.
I ended up taking a a small flat head screwdriver, and pried the sides of the petcock housing toward the broken stem center, and then it fell inside the radiator. Don't think it will hurt anything.
The radiator is only two years old this past July, and the petcock stem just broke all by itself I reckon. I installed a new Dorman petcock. Here is the petcock I am talking about that is common for plastic tank radiators.
