I recently replaced the water pump and it was a pain in the as* job to say the least.
I topped off the coolant, and then did it again. It's about 1/2" over the yellow "MAX" float. After running for a few minutes it leaks out of the hole pictured. I assume this is because it's a tiny bit "over full".
That's what this hole is, right? It's for when coolant expands too much and it needs to relieve?
My thought was to evac a small amount of coolant out and and run it again to check if it still leaks.
Any reason not to do this?
