Petcock Leak
As you know, there's a petcock at the bottom of the radiator on the passenger side,
and the coolant is slowly leaking there on my car.
I've searched about petcock leak, and all I've found are:
1. replacing the petcock is not easy because it's not a normal screw and in the worst case a part of it is left inside the radiator when pulled out.
2. there's no replacement seal available (especially when you cannot take it off)
What do you think is the best way to stop the leak there?
Do you think a liquid type anti-coolant sealant works?
and the coolant is slowly leaking there on my car.

Re: Petcock Leak
What is the safest way to replace the petcock?
I know there's a replacement petcock, but to replace that I need to take out the whole petcock parts safely, with nothing left in the radiator...

Re: Petcock Leak
Why is it snapped off ? It has plastic threads and unscrews . Unless its so brittle the ears snap off it will unscrew you can catch all your coolant and now would be a good time to change it I'm sure. Or remove it quickly and install a new one. tie a rag around your arm or be quick lol

Re: Petcock Leak
If replacing the petcock is an easy work, that will be the best choice.
Has anyone ever tried replacing it? Has anyone had any trouble doing that?

Re: Petcock Leak
the only option is to replace the petcock. just unscrew the old one and install the new one. the biggest issue here is not the petcock, but the bung in the radiator that it screws into. once it gets stripped, the petcock will no longer seat properly and won't seal. if that's the case you need a new radiator anyway.

Re: Petcock Leak
It looks like I cannot take the whole out once it goes into place.

Edit: never mind it wasn't one piece.
