For several weeks, my temperature gauge would spike after the car would run for about 5 or 6 minutes. Sometimes, the "Check Gauge" light would illuminate on the dashboard, but the light would go out after a short time and the temperature gauge would return back to its normal operating range.
Today, once the temperature gauge spiked, it stayed up and the "Check Gauge" light stayed on. I pulled the car off the road and the engine was indeed overheated. Steam coming out from on top the engine block near the firewall. I could also hear a hissing sound from the same area.
I changed the thermostat this evening, but the situation is still the same. No problems seem to be coming from around the water pump area.
