I have a 98 Chevy Silverado 1500 with a 350 and recently it lost antifreeze what could it be, it…

it sounded like before it leaked sounded like inside it was like a bubbling noise sometimes coming from the right of the dashboard.

pray it's not a leaking head gasket. Put some of this dye in and see where the dye comes out https://www.youtube.com/watch?v=rDuGeQnMOzk

I don't think the head gasket is bad though because it got to 230 then shut it off quickly.

it runs fine but I don't leave it on long because it will overheats and there are no misfires going on.

I found out it was manifold gaskets that are plastic and need to be replaced
