1999 challenger 1800 cooling system question

[hivoltage98]

2nd trip went well today but as I was flushing the engines I noticed one engine was spraying water out of a hole more than the other. Check out the picture. What’s this hole do and what should I be looking for?

Thanks

During flushing... dont' read anything into how much water is coming out where. The reason is... your garden hose isn't supplying the same pressure as the jet up will... and it putting water into a different location.

As long as the water is flowing out (nothing plugged) then you are ok.

The engine drain was clogged. We blew it out with air and now she drains fine. Clogs can be deadly.
