Well this was a fun day. On the way home car started over heating and I stop to cool and add coolant and water. Starts overheating again right away!
So I add more -- but I get to thinking. what if it's the water pump? Then it hit me! Head gasket? OMFG there's water in the oil dipstick! Any ideas on the cost to fix??
Edit: turns out to be a cracked head!
