My level was ok but I had just picked it up from the collision shop and they replaced the center radiator so I attributed it to a possible air bubble in the system.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

This makes me nervous. Where do I start?

POST 3Original post

a Flashing Temp Light indicate coolant level is too low.. I suggest fixing this before using the car

POST 4Original post

This just happened to me yesterday as well. Gauge read 180 but the light flashed. Pulled over, shut it down, and quickly searched 986forum for 'flashing temp light' on the iPhone. Found that it is most likely a low coolant level or faulty temp sensor. My level was ok but I had just picked it up from the collision shop and they replaced the center radiator so I attributed it to a possible air bubble in the system. I pulled up the bleed valve and drove home 380 miles keeping a close eye on temps and the light never came on again so I ruled out a faulty sensor. After I got home, closed the valve. No issues today and coolant level is within limits.

POST 5Original post

One thing to keep in mind as we reach cooler fall temperatures is that even though the level has been okay all summer, if you go to start the car after a day or two of freezing temperatures, the light may flash. It only means the coolant is low. But, keep in mind this is very, very sensitive. When mine flashed last week I added about four tablespoons of coolant to the overflow tank and it's now perfectly happy. The other thing to note is that if it flashes when you start up, it will not stop until the next time you start the car. So, if it flashes, run the car until the temperature needle moves a little bit. Pull over, turn off the car and start it up again. Voila, no more flashing light. Add a bit of coolant when you get home.

POST 6 / ORIGINAL POSTEROriginal post

Thanks guys! It was a little low. I added about 8 ounces of Ozarka water to make it just a hair above the MIN level. Should I be worried where the original 8 ounces went?

POST 7Original post

Bahh.. you could hypotetically guess so many thing.. I would just keep an eye on it to make sure you don't loose another 8 ounces in the next few weeks..

POST 8Original post

Mine just did the same thing on the way home, found the post and am now off and running. Thanks all
