Had the oil changed the other day in my wife's Outback and as we were running errands I noticed the temp gauge running hot, pulled over to check and it immediately went back to normal. Made it home without overheating and checked the coolant resovoir, which was low, so I filled her up. Drove about 120 miles the next day no issues. Checked yesterday and the level was at Min, topped it off to the Max. Ran it last night and when I cranked it up I smelled coolant smell. Checked the fluid again this morning, it's at the Min. Started the car and did not smell the smell. She just called and said when she started it she did.
It has NOT overheated since last week. There are no obvious signs of leakage (no puddles or drips that I can see). Everything feels/runs normal, heat works, etc. I'm keeping a close eye on it, but now I'm beginning to wonder if it's something serious.
Any ideas? I'm hoping something minor, like a leaky hose to the heater box or something.
Thanks,
Ed
