It seems that I have a coolant leak somewhere but I don't see the leak. After changing my oil I noticed my coolant tank was a little low so I poured in some coolant to a bit above the "MAX" line. I figured this shouldn't matter. Then after driving around doing errands I noticed that my temp was near max and the car was struggling. When I got home I saw that it was bone dry. The next morning I added coolant and idled the engine with no leaks anywhere. After another day of driving around the resevoir was bone dry again after noticing high heat. I was about to add some water I had in the trunk when all the coolant just gushed back in from the tubes on top of the resevoir when I opened the cap. It was full again. Now I'm confused. I left the car alone for a week and noticed it was nearly dry again when I looked before I drove off. I am really confused. Does anyone have any idea what's going on? Should I just go replace all my hoses? I have a roadtrip coming up and I can't deal with this the entire way.
