Looked up the the tread on draining and flushing the radiator. I used a 1/4 drive ratchet to open and drain the Pink, ran "flush" fluid and drained, filled with water to rise and thats when the petcock no longer opened with a 1/4 turn. Petcock rotates clockwise to a stop, However the 1/4 turn counter will not allow fluid to drain. I tried to force compressor air up into the drain port while turning petcock to see if it was plugged, also tried the wire poke, no luck.
Now what.
i was able to drain radiator w/ siphon. Coolant and water 70/30 added and car runs fine.
what are my options in regard to this petcock trouble.
Thanks, J.
