Overheating
Greetings forum,
On the way home from work last night my 97 C-5 water temp shot up to 250 degrees. I checked for radiator obstruction, antifreez level, etc. Antifreeze level was a little low so I topped it off. Went to work this am and it hit 250 again. Does this sound like a thermostat that just decided to quit opening? Hoses and cap appear to be fine.
Thanks in advance for any help.

Try turning on the air......that will cause the fans to kick on. If that lowers the temp, time to change & flush the system. I don't know why but some cars need flushed a lot sooner than others. Just a guess....

I had this happen once, I turned on the HEATER to 90, yes it got hot in the car, but it did lower the temp real fast as the coolant travels throught the heater, after a few mins I turned off the heater and things were fine, a trick I learned from my Dad a long time ago
