I have a 1990 Chevy S10 Blazer, It has 101k miles on it and drives good. I just got the truck last week and just the other day the "Check Gauges" light started blinking and the "Temperature Gauge" started bouncing up and down it's been doing it for two days now. I've checked all the fluids and there all full. I looked and asked many questions and have gotten different answers. Coolant Temperature Sensor, Thermostat, Head Gasket. Please help, I have no idea when it comes to cars.
