So my 650 decided to puke out the blue gatorade last night. It gave me the low coolant light and I was driving so I couldn't stop to check the level as I was not far from home. Next thing I see is the oil temp creeping to 250 and then the temperature warning light came on for a few seconds, I was already on the side streets and had the A/C off since it was nice outside. Speed up a little to get more air, light went away, which again it was on for a few seconds only and I was able to pull into a gas station quickly and shut it down. looks like the expansion tank cap failed from the pictures. Thankfully nothing else blew or got hot enough to do any real damage but already ordered the new parts. AAA membership saved my ass too.
