When engine temp gauge peaked, i popped the hood & engine did not seem overly warm or over heating?
when I had a air blockage due to a throttle repair inadvertently loosing rad fluid the radiator was cool to the touch.
This was due to lack of circulation through it and low level within it.
I could see temps spiking up on the obdiicc gauge with warning alarm sounding for a few secs then temps were back to normal while the stock gauge was normal. P&G'd home and air bled and no issues with spiking temps..
I changed out the thermostat this weekend. Car heat spiked again around 55 mph twice today then went down to close to normal when i pulled over and was at 25 mph. At idle, car is running at normal temp - not over heating. Took car home & parked it. Heater hoses are hot & was getting heat this morning. Previously i was not. One thing i did notice, my radiator fans are not on/working? Think this might be the issue now. Might of had a sticking thermostat also. Known issue w/ fans or relays going on these?
If you have "air" in the system, the radiator fan WILL NOT work. It is controlled by the sensor that only reads coolant temperatures, not air temperatures.......Period.

How does your coolant overflow container look?
That's the way to top up level if required normally; coolant backflows to radiator via suction when cooling down . A small amount of air can get burped out via the overflow container as well, then just top up again.
Wow! how much time you took to do this video?
Thanks! It took about 10 or 12 hours est. time over a week in several sessions. Most of the time spent was adding the annotations overlaying the screen.
The production was a learning curve and fun to make using mac's iMovie application; 'Gimp' graphics for still images etc; then some editing within YouTube for the annotations.
Glad you enjoyed it and I hope it helps!
Update: I burped the cooling system & ya it works! Drove it after the first burping/bleeding & the temp went just a bar or 2 above normal. Went back home and bled again & it's running at normal temp all the way to work! Thanks Williford! Plus my heat works normal again! So issue seems it was a sticking thermostat in either position at times causing no heat or the temp to spike every so often in the morning after starting out. This sounding board here on this site is great. You guys know what you are talking about. appreciate the help & the time that AbCAred00 took to create the burping video & Williford to help diagnose. I love my car again.
