I have a 1994 Mazda Protege with 234,000 miles.
It appeared to overheat today because temp gauge was close to the top of the heat range.
Details:
All cooling fans working, new thermostat, temp sensor, and new cap as well.
Outside temp was about 93 degrees and I was stuck in stop n go traffic for about 30 minutes.
Temp went back to normal once I got out of the traffic.
Any ideas as to why the temp gauge went so high?
Thanks.
