My truck has 135000k miles on it. A few days ago i noticed while sitting in rush hour traffic that the temperature would get way past the halfway mark, almost to the overheating mark. Once i got past the traffic the temp gage would show normal temp again up untill i caught a red light. Then the temp would rise again quickly. I checked the coolant level and it seems fine. I replaced the thermostat but that did not fix the problem either. Could the waterpump be causing the problem?
