Overheating 308

First check to see if your fans are comming on. If not it could be something as simple as a Relay.
Or the fan could have burned up.

Overheating in traffic is usually a fan not helping the cooling.

But it could be something else

 

check the cap on the expansion tank
could be bad

Check the relay and it also could be a faulty fan temp sensor at the bottom of the radiator that tells the fans to kick on. You can jump the wiring to see if the fans are working and determine if it is the radiator fan sensor.

That part is cheap and is cross referenced to a VW rabbit part from the 80's.

Here is a thread on the subject.

I wouldn't worry about the headgasket just yet, If you were able to get it turned off quickly I think you will be fine. But we were not there.

I know my fans craped out on me and I over heated it once the car was Blowing through the overflow tube and just waited for it to cool.

Added coolant and limped it home I then found that the fans were not running and it was the damn $20 relay I also changed my expansion tank cap to a new one.

 

Fill and bleed correctly. Replace expansion cap, and make sure the fans are coming on.

Thought I'd add to this thread.
The car was running fine after sorting an overheating issues like 2 years ago.
Did a full fluid change very early Spring & installed the petcock drain under the front radiator (mental note - check - I think I heard it rattling against the floor pan)
Ran the car, she was fine.
The other day, some bad accident/incident on Rt 80 shut down 4 lanes of an 8 lane highway & traffic was backed up for 2 miles with nowhere to get off.
I noticed the car was running hot (235ish) It was 85 and high humidity. But normally she doesn't run that hot. radiator recored 2 years ago, Aladdin radiator autobleeders have been working flawlessly, but I turned on the blower & heater to full as I inched forward in a parking lot of cars praying to the Ferrari gods I didn't have to pull over to let her cool down. Besides emergency vehicles were running up & down the shoulder so nowhere to pull over.

I did make it home and since the fluid change was the last thing I did, I figured check the system for air. Sure enough, she had that bloated feeling. Lots of air out of the front radiator. The auto-air bleeder didn't work for some reason.
First time I've had trouble with it. Perhaps the system sucked in air when I removed it (when cool). but I re-bled it, let it idle & she didn't go above 210 where she should be with both fans running full-tilt. I'll have to check the engine elbow for air & then take her out to see how she is.
Those valves are good for 3 years. Perhaps they are tired.

 

Auto bled valves can get stuck to the seat- soak it in vinegar to see if it cleans it. Or try the liquid cleaner they use to de scale an iron.
